Legacy apps weren't designed to run in a modern distributed platform like Docker. They have their own ideas about logging, configuration and health which don't translate to the world of containers and make transformation projects hard. This session shows you how to bring your old apps into the modern world, and integrate them with Docker - without changing code. We'll cover patterns for all the core application concerns: * logging * configuration * monitoring * health * dependency management The sample apps will be in .NET and Java, and will show you how to turn your existing apps into good Docker citizens.

Demystifying container connectivity with kubernetes in docker
The addition of Kubernetes support to Docker Enterprise Platform presents deployments with interesting new abstractions for application connectivity. Users and Operators are often challenged with rationalizing how pod networking (with CNI plugins like Calico or Flannel), Services (via kube-proxy) and Ingress work in concert to enable application connectivity within and outside a cluster. Similarly, given the dynamic and transient nature of containerized microservice workloads, how to leverage scalable and declarative approaches like network policies to express segmentation and security primitives.
This session provides an illustrative walkthrough of these core concepts by going through common deployment architectures providing design, operations, and scale considerations based on experience from numerous production deployments. The session will also showcase how to complement application and operations workflows with policy-driven business, compliance and security controls typically required in enterprise production deployments.
Windows container security
"The majority of the container security discussion revolves around containers on Linux while the security of containers in Windows is left as a mystical black box. In this talk we'll peel back the curtain and dive in to how Windows containers are secured.
Does Windows have namespaces? How does it compose the layers of a container's filesystem? How does it limit resource usage of containers? I heard there's a Hyper-V isolation thing, what's that about?
We'll answer all these questions and more!"
Building your production tech stack for docker container platform
This session will focus on the practicals of building a fully-functional stack of container cluster tools, with different options for stacking those tools from the OS-up.
We’ve all seen examples of common technologies stacks, like the good ol’ LAMP and MEAN stacks for apps, but what about lower-level infrastructure? And can we get it without cloud vendor lock in please? Oh and pure containers and infrastructure-as-code too?
With Docker, sure thing! This session will cover:
Which OS/Distro and Kernel to use
VM’s or Bare Metal
Recommended Swarm architectures
Tool stacks for “pure open source”, “cloud-service based”, and “Docker EE” scenarios
Demos of these tools working together including InfraKit, Docker, Swarm, Flow-Proxy, ELK, Prometheus, REX-Ray, and more.
Networking in Docker EE 2.0 with Kubernetes and Swarm
The presentation is about the operator goal from networking perspective and how it is influenced by both swarm and kubernetes on the Docker EE platform
A vision of persistence
Pull, push, clone, it is all in your daily workflow. But what if this wasn't your source code or your container, but the state of your whole computer? Push your production database over to another machine? No problem!
This talk shows how you can use Dotmesh with LinuxKit to work with persistent data on your server as simply as you work with git. This workflow helps unleash new ways of working with servers and data. Immutable infrastructure from LinuxKit meets controlled and manageable data storage from Dotmesh. Combining these two open source projects allows new possibilities in how to manage your infrastructure.
Building a Secure Supply Chain with Docker
Creating a Secure Supply Chain of images is vitally important. Every organization needs to weigh ALL options available and understand the security risks. With so many options for images, it is tough to pick the right ones or even to create your own. Ultimately, every organization needs to know the provenance of all the images. Then once the images are imported into the infrastructure, a vulnerability scan is vital. Docker Trusted Registry with Image Scanning will give organizations insight into any vulnerabilities. Better yet, its automated with a succinct audit trail, so you can still take that vacation you had planned and make your security team happy.

When you have to say ""YES"" to everything, what does that really mean?
The Boston Consulting Group (BCG) is a global management consulting firm that advises industry leading companies on value creation strategies, innovation, transformation, supply chain management and much more. BCG provides recommendations and analytics that are custom tailored to the needs of each client. To do this BCG is transforming what used to be presentations and manual models into software that is prototyped and distributed to their client to run on their infrastructure - in effect changing the way BCG delivers value.
However the productization process poses unique challenges and opportunities. Their clients have every type of infrastructure and application stack within their IT environments, how can BCG ensure that the custom built analytics applications will operate well at scale in their client's production environment - especially when it is an environment that they don't control? The bespoke nature of the BCG business led the team to embark on an engineering led journey to containerization with Docker. Attend this session to learn more about the approach, challenges and how BCG is enabling transformation with Docker Enterprise Edition.

Java in a world of containers
"Container technologies such as Docker are rapidly becoming the de-facto way to deploy cloud applications, and Java is committed to being a good container citizen. This session will explain how OpenJDK fits into the world of containers, specifically how it fits with Docker images and containers.
The session will focus on the production of optimized Docker images containing a JDK. We will introduce technologies such as jlink, that can be used to reduce the size of the created image. The session will explain Alpine/musl support for an effective image and runtime. The session will also talk about and the inclusion of Class Data Sharing (CDS) archives and Ahead of Time (AOT) shared object libraries for improving startup time.
The attendees will learn about the recent work that has gone into OpenJDK for interacting with container resource limitations."

Ask better questions & identify the real problems you want to solve
Use command line tools to inspect internal Swarm and Kubernetes components
Debug and troubleshoot interactions between Enterprise Edition components
Troubleshoot Docker Enterprise Edition Windows nodes
Apply these skills to troubleshooting Docker Enterprise Edition
Accessible hpc for everyone with docker and containers
This session will introduce High Performance Computing and outline the challenges when trying to fit those workloads into containers. Afterwards the community solutions are touched on before an approach based on proper Docker is shown. The talk will wrap-up with an outlook how containers can foster scientific discoveries by allowing HPC to be used by everyone.
DockerCon EU 2015: Placing a container on a train at 200mph
Presented by Casper S. Jensen, Software Engineer, Uber
At Uber, we've been introducing Docker to give service owners more control over their environments. However, everything at Uber is moving very fast so we have had to do it a way such that Docker fitted into the existing infrastructure and services could be migrated seamlessly to Docker without any service interruptions. In this talk we will talk about the challenges we faced while doing this, such as handling both non-Docker and Docker builds, image replication, integration with our deployment systems and other challenges when deploying Docker at scale.
Production sec ops with kubernetes in docker
In this talk, Scott Coulton will walk through how to build a container as a service platform with Docker EE. Starting from scratch he will help you figure out what orchestrator to choose by deep diving into the technical differences between swarm and kubernetes on the EE platform as well as cover some of the practical considerations that could influence your decision. He will also share various automation solutions to deploy your cluster into production. Once the cluster is up and and running, Scott will delve into sec ops and discuss security best practices - including signing images in DTR (Docker Trusted Registry) and CVE scanning to provide a secure supply chain into production. You’ll leave this talk with the knowledge needed to build your own container platform in production. And did I mention it will all be done live, step-by-step?
Containerizing Hardware Accelerated Applications
Many applications allow you to use hardware such as GPUs and FPGAs for acceleration. Common examples include media processing and offloading highly parallel work to a GPU. Applications that use accelerators are resource heavy and have stacks spanning kernel and user space; accelerators often have their own requirements for operating system support and kernel versions. While it may not seem intuitive to containerize this type of application, the use of containers provides benefits such as reduced setup time from container reuse, reduction in dependency conflicts and dependency on a specific operating system, and easier updates.
In this session I show a media processing stack, making use of containers alongside a GPU. Specifically, I explain the kernel and user space divide of a hardware-accelerated transcode application using a device exposed to the container. This specific stack is an interesting case because of its dependency on hardware, use of a custom kernel and libraries, and operating system requirements. Our investigations have shown the use of containers has minimal performance overhead compared to running natively. Furthermore, we can quickly deploy on other machines with reduced configuration effort. There are some aspects of the application not suited to containerization, however. Since the application relies on a custom kernel, the use of containers does not necessarily increase portability. Improvement in this area would require rethinking how the applications are developed and distributed. Other areas of innovation include things such as Docker plugins to check for compatibility between the container software and host kernel.
Why I wish I'd Heard of Docker when I was 12 - Finnian Anderson
It’s almost exactly five years since I powered up my first Raspberry Pi - a baffling 12th birthday present! In this talk I’ll share my 5 year coding journey from HTML & PHP via Node.js to (No)SQL and Docker. Along the way I’ll show some atrocious git commits, some awful hacks and some awesome projects. These include a containerised URL shortener, an instant food calorie calculator and an exam revision app that all really should have used Docker. I’ll go into detail on my latest Docker-based RPi cluster (inspired by Captain @AlexEllisUK) with it’s PiGlow load monitor and servo-based physical load detector. I’ll explain how Alex’s support and advocacy got me invited to DockerCon and give a demo of a Raspberry Pi-driven hardware gauge to monitor a Docker Swarm in real time.
Proactive ops for container orchestration environments
Break -> inspect -> fix is the Ops workflow for infrastructure stacks of the past. Distributed infrastructure and applications claim to be the new generation, but why is it so much more painful to maintain and troubleshoot them? Much of the pain comes from outdated operational models relying on reactive or, worse yet, manual monitoring and Ops.
This talk lays out a proactive Ops model for container infrastructure. By focusing on event monitoring, infrastructure state monitoring, trend analysis, and distributed log collection, a proactive Ops model delivers observability for distributed apps that was not possible before. Using real-world examples from Swarm and Kubernetes, we'll demonstrate the tools used and how we relieve Ops pain in container orchestration.
DCSF 19 Building Your Development Pipeline
Oliver Pomeroy, Docker & Laura Tacho, Cloudbees
Enterprises often want to provide automation and standardisation on top of their container platform, using a pipeline to build and deploy their containerized applications. However this opens up new challenges; Do I have to build a new CI/CD Stack? Can I build my CI/CD pipeline with Kubernetes orchestration? What should my build agents look like? How do I integrate my pipeline into my enterprise container registry? In this session full of examples and how-to's, Olly and Laura will guide you through common situations and decisions related to your pipelines. We'll cover building minimal images, scanning and signing images, and give examples on how to enforce compliance standards and best practices across your teams.
Considerations for operating docker at scale
"Scale" happens along 3 different aspects: (1) applications and their services scale up and down leading to (2) the infrastructure scaling up to meet the needs of the applications, and finally (3) sites scale across multiple locations, including movement to public cloud. In this session, we will talk about how Docker EE scales along all three of these dimensions to give you a consistent platform for running your applications:
1. At the application level: how do you manage application state & health along with resource and security constraints to scale containers up and down up in a controlled fashion?
2. The infrastructure level: as your application estate grows on the Docker EE platform you will need to scale across more nodes. How do automate the provisioning of these new nodes and how do you integrate the Docker EE platform layer with your existing infrastructure systems and tools.
3. Finally, we'll talk about distributed scale: how do you take what works for applications in one data center and spread it across multiple sites, in an integrated fashion so you can operate seamlessly?

DCEU 18: Docker Containers in a Serverless World
Jules Testard - Software Engineer, Docker Inc
Since the advent of AWS Lambda in 2014, the Function as a Service (FaaS) programming paradigm has gained a lot of traction in the cloud community. Since then, interest has increased for developers and entreprises to build their own open source solutions on top of Kubernetes. A number of competing frameworks in this space have been developed. In this talk, we will look at three specific frameworks (OpenFaas, Nuclio and FN) and for each framework we will: Show how to create, deploy, and invoke a function using that framework Show how Docker images and containers are used by each framework under the hood Investigate how the frameworks leverage KNative to build, ship and run applications on Kubernetes
Activision's Skypilot: Delivering Amazing Game Experiences Through Containeri...
"Technologies that are going to affect our lives in the next decade are being tested and developed in the video game sphere." In January 2016 Activision approved a pilot project to build a containerised continuous delivery pipeline using Docker. This project spanned multiple devops teams and would culminate in launching a production title "Skylanders Imaginators" in October 2016. The Mission Statement : “Our mission is to deliver an amazing build, test and deploy pipeline that aims to be so reliable, effective and easy to use that our product and title departments will end up writing high value gaming services all day long without giving a second thought to how they may reliably deliver these in record time.” This talk will discuss the cultural and technical challenges faced throughout the pilot. Spoiler alert: Not everyone was happy with the decision to use Docker. The talk will cover the concerns and how we handled them. It will cover why it is important, especially in the games industry, to be evaluating and integrating technologies like Docker in order to remain relevant. For the first time in Demonware history developers were responsible for the launch and support of a title. We are also the first studio under Activision to be running Docker in Production.

We will cover the CD process for Docker, Docker swarm, Docker networking and service discovery. The audience will leave with a solid foundation of how to build a production ready swarm cluster (A github repo with code will be given). They will also have the knowledge of how to implement a CD framework using Docker.
DockerCon SF 2015: Docker in the New York Times Newsroom
Eric Buth's Presentation at DockerCon SF 2015:
Talk Description: In the New York Times newsroom you’ll find a deeply heterogeneous technology environment that exists – by necessity – outside of the larger, more well-defined development pipelines of the rest of the organization. On the Interactive News team, part of our mission is providing a reliable path to production for designers/developers/reporters who need to be able to make their own technology choices on what can be extremely tight deadlines.
Containerization is becoming increasingly important to these efforts, and we’re ready to share our experience working with Docker and crafting complementary orchestration, communication, and organization solutions.
DockerCon EU 2015: Cultural Revolution - How to Mange the Change Docker Brings
Presentation by Ian Miell, author of 'Docker in Practice'
The adoption of Docker brings with it many challenges, not all of themtechnical. There is a clear vision of Docker regularly articulated thatencompasses microservices, decoupled applications, agile and continuous deliveryand integration, and DevOps. But the application of this vision often flounders when confronted by the legacy structures of working and successful businesses.
This talk draws on the experienced gained from several attempts to lead changewithin technical organisations. The speaker experienced both failure to effectchange (through productization of a bespoke software stack, and the introduction of Erlang), and success (moving to a Continuous Improvement modelof complex software maintenance). These experiences informed a successful drive to Docker as the build and delivery system of a 700-strong software company,with significant efficiency improvements.
As with most historical revolutions, the integration of the vision with realityresulted in corners cut and principles compromised in order to effect change.This talk is a discussion of the lessons learned from these experiences in an effort to help the listener clarify and overcome the unique challenges their own organisation brings to making change happen.
How to build your containerization strategy
The Docker Enterprise Edition platform helps customers deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the Docker EE container platform, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together.
In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data, ...), how your org chart can influence whether you deploy a CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying Docker in your enterprise.
DCSF 19 Microservices API: Routing Across Any Infrastructure
Alex Hokanson + Brett Inman, Docker
Microservice architectures can be difficult to implement. Specifically how to route to the a service correctly and ensure that traffic is spread across all instances of that service. What happens in a cloud environment where it is normal to lose and gain service instances as a part of daily operations? How do you configure something to be able to consistently route to your service when you don’t even know where your service is running!? At Docker, we developed our own highly available and automated API server on top of HAProxy with deep integration with Consul. Our API server acts as a service discovery and load balancing service to ensure availability in a highly dynamic environment. In addition to running such a complex application, we need to support thousands of requests per second while being able to monitor every request that comes through--that is no small feat!
In addition to running a highly available API server, we also recently migrated it from running natively on Ubuntu 14.04 to run all components inside of containers by using Kubernetes with Docker Enterprise. With the containerization journey came some benefits along with new challenges that were not foreseen.

It will cover why it is important, especially in the games industry, to be evaluating and integrating technologies like Docker in order to remain relevant. For the first time in Demonware history developers were responsible for the launch and support of a title. We are also the first studio under Activision to be running Docker in Production.

We will cover the CD process for Docker, Docker swarm, Docker networking and service discovery. The audience will leave with a solid foundation of how to build a production ready swarm cluster (A github repo with code will be given). They will also have the knowledge of how to implement a CD framework using Docker.
DockerCon SF 2015: Docker in the New York Times Newsroom
Eric Buth's Presentation at DockerCon SF 2015:
Talk Description: In the New York Times newsroom you’ll find a deeply heterogeneous technology environment that exists – by necessity – outside of the larger, more well-defined development pipelines of the rest of the organization. On the Interactive News team, part of our mission is providing a reliable path to production for designers/developers/reporters who need to be able to make their own technology choices on what can be extremely tight deadlines.
Containerization is becoming increasingly important to these efforts, and we’re ready to share our experience working with Docker and crafting complementary orchestration, communication, and organization solutions.
DockerCon EU 2015: Cultural Revolution - How to Mange the Change Docker Brings
Presentation by Ian Miell, author of 'Docker in Practice'
The adoption of Docker brings with it many challenges, not all of themtechnical. There is a clear vision of Docker regularly articulated thatencompasses microservices, decoupled applications, agile and continuous deliveryand integration, and DevOps. But the application of this vision often flounders when confronted by the legacy structures of working and successful businesses.
This talk draws on the experienced gained from several attempts to lead changewithin technical organisations. The speaker experienced both failure to effectchange (through productization of a bespoke software stack, and the introduction of Erlang), and success (moving to a Continuous Improvement modelof complex software maintenance). These experiences informed a successful drive to Docker as the build and delivery system of a 700-strong software company,with significant efficiency improvements.
As with most historical revolutions, the integration of the vision with realityresulted in corners cut and principles compromised in order to effect change.This talk is a discussion of the lessons learned from these experiences in an effort to help the listener clarify and overcome the unique challenges their own organisation brings to making change happen.
How to build your containerization strategy
The Docker Enterprise Edition platform helps customers deploy and manage applications faster and it secures the application pipeline at a lower cost than traditional application delivery models. But it takes more than just great technology to achieve the desired results. The organization and culture of your enterprise directly impacts what you transform, how it’s done, and who does it. Success requires a strategy for how you will govern the Docker EE container platform, how to assess your application estate, what your delivery pipeline will look like, and how to ensure developers, operators, security teams and others play nicely together.
In this talk I will cover topics such as different types of workloads (legacy, microservices, FaaS, big data, ...), how your org chart can influence whether you deploy a CaaS (Containers as a Service) vs CLaaS (Clusters as a Service), how "shifting left" can determine if you can outsource, centralized vs distributed CI/CD and how containers play a role, transforming your pets into cattle, how giant whale balloons are used for onboarding, and a prescriptive and comprehensive methodology for successfully deploying Docker in your enterprise.
DCSF 19 Microservices API: Routing Across Any Infrastructure
Alex Hokanson + Brett Inman, Docker
Microservice architectures can be difficult to implement. Specifically how to route to the a service correctly and ensure that traffic is spread across all instances of that service. What happens in a cloud environment where it is normal to lose and gain service instances as a part of daily operations? How do you configure something to be able to consistently route to your service when you don’t even know where your service is running!? At Docker, we developed our own highly available and automated API server on top of HAProxy with deep integration with Consul. Our API server acts as a service discovery and load balancing service to ensure availability in a highly dynamic environment. In addition to running such a complex application, we need to support thousands of requests per second while being able to monitor every request that comes through--that is no small feat!
In addition to running a highly available API server, we also recently migrated it from running natively on Ubuntu 14.04 to run all components inside of containers by using Kubernetes with Docker Enterprise. With the containerization journey came some benefits along with new challenges that were not foreseen.

Training Bootcamp - MainframeDevOps.pptx
Cloud Migration services from your on-premise environment can sometimes be very simple and other times an extremely complicated project to implement. For either scenario, there are always considerations to bear in mind when doing so. This course has been designed to highlight these topics to help you ask the right questions to aid in a successful Cloud migration.
Within this course, we look at how timing plays an important part in your project's success and why phased deployments are important. Security is also examined where we focus on a number of key questions that you should have answers to from a business perspective before your Cloud migration. One of the biggest decisions is your chosen public cloud vendor, how do you make the decision between the available vendors, what should you look for when selecting you will host your architecture, this course dives into this question to help you finalize your choice.
Understanding the correct deployment model is essential, it affects how you architect your environment and each provides different benefits, so gaining the knowledge. I look at how you can break this question down to help you with your design considerations. We also cover service readiness from your on-premise environment and how to align these to the relevant Cloud services. Your design will certainly be different from your on-premise solution, I discuss the best approach when you start to think about your solution design, some of the dos and some of the don’ts.
Once you have your design, it’s important to understand how you are actually going to migrate your services ensuring optimum availability and minimal interruption to your customer base, for example looking at Blue/Green and Canary deployments. Cloud migration allows for some great advantages within your business continuity plans, as a result, I have included a lecture to discuss various models that work great within the Cloud.

Containerize Your Game Server for the Best Multiplayer Experience
Raymond Arifianto, AccelByte and
Mark Mandel, Google -
We have been deploying containerized micro-services for our Game Backend Services for a while. Now we are tackling the challenge to scale up fleets of game dedicated servers in multiple regions, multiple data centers and multiple providers - some in bare metal, some in Cloud. So we leverage docker containerization to deploy Game Servers to achieve Portability, Fast Deployment and Predictability, enabling us to scale up to thousands of servers, on demand, without a sweat.
How to Improve Your Image Builds Using Advance Docker Build
Nicholas Dille, Haufe-Lexware + Docker Captain -
Docker continues to be the standard tool for building container images. For more than a year Docker ships with BuildKit as an alternative image builder, providing advanced features for secret and cache management. These features help to make image builds faster and more secure. In this session, Docker Captain Nicholas Dille will teach you how to use Buildkit features to your advantage.
Build & Deploy Multi-Container Applications to AWS
Lukonde Mwila, Entelect -
As the cloud-native approach to development and deployment becomes more prevalent, it's an exciting time for software engineers to be equipped on how to dockerize multi-container applications and deploy them to the cloud.
In this talk, Lukonde Mwila, Software Engineer at Entelect, will cover the following topics:
- Docker Compose
- Containerizing an Nginx Server
- Containerizing an React App
- Containerizing an Node.JS App
- Containerizing anMongoDB App
- Runing Multi-Container App Locally
- Creating a CI/CD Pipeline
- Adding a build stage to test containers and push images to Docker Hub
- Deploying Multi-Container App to AWS Elastic Beanstalk
Lukonde will start by giving an overview of how Docker Compose works and how it makes it very easy and straightforward to startup multiple Docker containers at the same time and automatically connect them together with some form of networking.
After that, Lukonde will take a hands on approach to containerize an Nginx server, a React app, a NodeJS app and a MongoDB instance to demonstrate the power of Docker Compose. He'll demonstrate usage of two Docker files for an application, one production grade and the other for local development and running of tests. Lastly, he'll demonstrate creating a CI/CD pipeline in AWS to build and test our Docker images before pushing them to Docker Hub or AWS ECR, and finally deploying our multi-container application AWS Elastic Beanstalk.
Securing Your Containerized Applications with NGINX
Kevin Jones, NGNIX -
NGINX is one of the most popular images on Docker Hub and has been at the forefront of the web since the early 2000's. In this talk we will discuss how and why NGINX's lightweight and powerful architecture makes it a very popular choice for securing containerized applications as a sidecar reverse proxy within containers. We will highlight important aspects of application security that NGINX can help with, such as TLS, HTTP, AuthN, AuthZ and traffic control.
How To Build and Run Node Apps with Docker and Compose
Kathleen Juell, Digital Ocean -
Containers are an essential part of today's microservice ecosystem, as they allow developers and operators to maintain standards of reliability and reproducibility in fast-paced deployment scenarios. And while there are best practices that extend across stacks in containerized environments, there are also things that make each stack distinct, starting with the application image itself.
This talk will dive into some of these particularities, both at the image and service level, while also covering general best practices for building and running Node applications with database backends using Docker and Compose.
Hands-on Helm
Jessica Deen, Microsoft -
Helm 3 is here; let's go hands-on! In this demo-fueled session, I'll walk you through the differences between Helm 2 and Helm 3. I'll offer tips for a successful rollout or upgrade, go over how to easily use charts created for Helm 2 with Helm 3 (without changing your syntax), and review opportunities where you can participate in the project's future.
Distributed Deep Learning with Docker at Salesforce
Jeff Hajewski, Salesforce -
There is a wealth of information on building deep learning models with PyTorch or TensorFlow. Anyone interested in building a deep learning model is only a quick search away from a number of clear and well written tutorials that will take them from zero knowledge to having a working image classifier. But what happens when you need to deploy these models in a production setting? At Salesforce, we use TensorFlow models to help us provide customers with insights into their data, and we do this as close to real-time as possible. Designing these systems in a scalable manner requires overcoming a number of design challenges, but the core component is Docker. Docker enables us to design highly scalable systems by allowing us to focus on service interactions, rather than how our services will interact with the hardware. Docker is also at the core of our test infrastructure, allowing developers and data scientists to build and test the system in an end to end manner on their local machines. While some of this may sound complex, the core message is simplicity - Docker allows us to focus on the aspects of the system that matter, greatly simplifying our lives.
The First 10M Pulls: Building The Official Curl Image for Docker Hub
James Fuller, webcomposite s.r.o. -
Curl is the venerable (yet very modern) 'swiss army knife' command line tool and library for transferring data with URLs. Recently we (the Curl team) decided to build a release for Docker Hub. This talk will outline our current development workflow with respect to the docker image and provide insights on what it takes to build a docker image for mass public consumption. We are also keen to learn from users and other developers how we might improve and enhance the official curl docker image.
Monitoring in a Microservices World
Fabian Stäber, Instana -
In recent years, we saw a great paradigm shift in software engineering away from static monolithic applications towards dynamic distributed horizontally scalable architectures. Docker is one of the key technologies enabling this development. This shift poses a lot of new challenges for application monitoring, ranging from practical issues (need for automation) to technical challenges (Docker networking) to organizational topics (blurring line between software engineers and operations) to fundamental questions (define what is an application). In this talk we show how Docker changed the way we do monitoring, how modern application monitoring systems work, and what future developments we expect.
COVID-19 in Italy: How Docker is Helping the Biggest Italian IT Company Conti...
Clemente Biondo, Engineering Ingegneria Informatica -
When the COVID 19 pandemic started, Engineering Ingegneria Informatica Group (1.25 billion euros of revenues, 65 offices around the world, 12.000 employees) was forced to put their digital transformation to the test in order to maintain operational continuity. In this session, Clemente Biondo, the Tech Lead of the Information Systems Department, will share how his company is reacting to this unforeseeable scenario and how Docker-driven digital transformation had paved the path for work to continue remotely. Clemente will discuss learnings moving from colocated teams, manual approaches, email based-business processes, and a monolithic application to a mature DevOps culture characterized by a distributed autonomous workforce and a continuous deployment process that deploys backward-compatible Docker containerized microservices into hybrid multi cloud datacenters an average of twice a day with zero-downtime. He will detail how they use Docker to unify dev, test and production environments, and as an efficient and automated mechanism for deploying applications. Lastly, Clemente shares how, in our darkest hour, he and others are working to shine their brightest light.
Predicting Space Weather with Docker
Chris Lauer, NOAA Space Weather Prediction Center -
This is the story of how adopting a containerized workflow changed the way our small software team works at NOAA’s Space Weather Prediction Center. Our old architecture, a big ball of mud shared-database integration, just wasn’t cutting it - it was killing our agility. Over the past two years, our small team has adopted a microservice style architecture, using Docker with docker-compose and environment files as our deployment strategy for all new development. We’ve discovered the joys of using containers for identical dev, staging, and production environments. We work closely with scientists: much of the code we’re running has complicated and conflicting library dependencies. Docker captures these beautifully - we’ve even had some success teaching our scientists to use it! I’ll share what we’ve learned, some of the persistent challenges we face, and one place we really got it wrong. This talk builds off of a popular hallway track from DockerCon 2019.
Become a Docker Power User With Microsoft Visual Studio Code
Brian Christner, 56k + Docker Captain -
In this session, we will unlock the full potential of using Microsoft Visual Studio Code (VS Code) and Docker Desktop to turn you into a Docker Power User. When we expand and utilize the VS Code Docker plugin, we can take our projects and Docker skills to the next level. In addition to using VS Code, we streamline our Docker Desktop development workflow with less context switching and built-in shortcuts. You will learn how to bootstrap new projects, quickly write Dockerfiles utilizing templates, build, run, and interact with containers all from VS Code.
How to Use Mirroring and Caching to Optimize your Container Registry

Monolithic to Microservices + Docker = SDLC on Steroids!
Ashish Sharma, SS&C Eze -
SS&C Eze provides various products in the stock market domain. We spent the last couple of years building Eclipse which is an investment suite born in cloud. The journey so far has been very interesting. The very first version of the product were a bunch of monolithic windows services and deployed using Octopus tool. We successfully managed to bring all the monolithic problem to the cloud and created a nightmare for ourselves. We then started applying microservices architecture principles and started breaking the monolithic into small services. Very soon we realized that we need a better packaging/deployment tool. Docker looked like a magical solution to our problem. Since its adoption, It has not only solved the deployment problem for us but has made a deep impact on different aspects of SDLC. It allowed us to use heterogeneous technology stacks, simplified development environment setup, simplified our testing strategy, improved our speed of delivery, and made our developers more productive. In this talk I would like to share our experience of using Docker and its positive impact on our SDLC.
Kubernetes at Datadog Scale
Ara Pulido, Datadog -
Container technologies, although not new, have increased their popularity in the past few years, with container orchestrators allowing companies around the world to adopt these technologies to help them ship and scale microservices with precision and velocity. Kubernetes is currently the most popular container orchestration platform, and while many organizations are migrating their workloads to it, Kubernetes is still relatively immature. New corner cases, errors, and quirks are regularly discovered as users push the boundaries of size and scale. When Datadog adopted Kubernetes we discovered some of these boundaries the hard way, and we continuously challenge and modify our infrastructure decisions in order to fit our use case. Join me in this talk for our story on what we learned while we scaled our Kubernetes clusters, the contributions to Kubernetes we made along the way, and how you can apply those learnings when growing your Kubernetes clusters from a handful to hundreds or thousands of nodes.
Labels, Labels, Labels
Andy Clemenko, StackRox -
One underutilized, and amazing, thing about the docker image scheme is labels. Labels are a built in way to document all aspects about the image itself. Think about all the information that the tags inside your clothing carry. If you care to look you can find out everything about the garment. All that information can be very valuable. Now think about how we can leverage labels to carry similar information. We can even use the labels to contain Docker Compose or even Kubernetes Yaml. We can even include labels into the CI/CD process making things more secure and smoother. Come find out some fun techniques on how to leverage labels to do some fun and amazing things.
Using Docker Hub at Scale to Support Micro Focus' Delivery and Deployment Model
Patrick Deloulay, Micro Focus -
Micro Focus started their digital transformation 3 years ago, moving the entire portfolio into hundreds of container images. Leveraging Docker Hub as our primary registry service, we will cover how we ended up building a simple but secure push/pull model to publish and deliver our premium assets to our customers and partners to both meet the high agility of our DevOps teams while greatly simplifying the deployment of our applications.

From Fortran on the Desktop to Kubernetes in the Cloud: A Windows Migration S...
Elton Stoneman, Docker Captain + Container Consultant and Trainer
How do you provide a SaaS offering when your product is a 10-year old Fortran app, currently built to run on Windows 10? With Docker and Kubernetes of course - and you can do it in a week (... to prototype level at least).
In this session I'll walk through the processes and practicalities of taking an older Windows app, making it run in containers with Kubernetes, and then building a simple API wrapper to host the whole stack as a cloud-based SaaS product.
There's a lot of technology here from a real world case study, and I'll focus on:
- running Windows apps in Docker containers
- building a .NET Core API which can run in Linux or Windows containers
- running the stack in Kubernetes with Docker Desktop locally and AKS in the cloud
- configuring AKS workloads in Azure to burst out to Azure Container Instances
And there's a core theme to this session: Docker and Kubernetes are complex technologies, but they're the key to modern development. If you invest time learning them, they make projects like this simple, portable, fast and fun.
