Oscon 2017: Build your own container-based system with the Moby project
Build your own container-based system
with the Moby project
Docker Community Edition—an open source product that lets you build, ship, and run containers—is an assembly of modular components built from an upstream open source project called Moby. Moby provides a “Lego set” of dozens of components, the framework for assembling them into specialized container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.
Patrick Chanezon and Mindy Preston explain how you can leverage the Moby project to assemble your own specialized container-based system, whether for IoT, cloud, or bare-metal scenarios. Patrick and Mindy explore Moby’s framework, components, and tooling, focusing on two components: LinuxKit, a toolkit to build container-based Linux subsystems that are secure, lean, and portable, and InfraKit, a toolkit for creating and managing declarative, self-healing infrastructure. Along the way, they demo how to use Moby, LinuxKit, InfraKit, and other components to quickly assemble full-blown container-based systems for several use cases and deploy them on various infrastructures.

Practical Container Security by Mrunal Patel and Thomas Cameron, Red Hat
You can secure your containerized microservices without slowing down development. Through a combination of Linux kernel features and open source tools, you can isolate the host from the container and the containers from each other, as well as finding vulnerabilities and securing data. Two of Red Hat's Docker contributors will discuss the state of container security today, covering Linux namespaces, SElinux, cgroups, capabilities, scan, seccomp, and other tools you can use right now.
On-the-Fly Containerization of Enterprise Java & .NET Apps by Amjad Afanah
Dockerizing brownfield enterprise applications can often be a daunting task - involving changes to the application code/configuration and existing build processes. The DCHQ platform provides “on-the-fly” containerization of both Linux & Windows enterprise applications – including Java, Oracle, .NET and others. By doing so, DCHQ transforms non-cloud-native applications into completely portable applications that can take advantage of cloud scaling, storage redundancy and most importantly, deployment agility without introducing a single change to the application source control repository.
In this session, we will cover the deployment automation of an Enterprise Java application with PostgreSQL multi-host cluster set up for Master-Slave replication and automated storage management with redundant EBS volumes on AWS using DCHQ + EMC REX-Ray. We will also cover the deployment automation of an Enterprise .NET application demonstrating the application life-cycle management capabilities post-provision -- including monitoring, alerts, continuous delivery, application backups, scale in/out, in-browser terminal to access the containers, log streaming, and application updates.
DCEU 18: Docker Container Networking
Francisco Javier Ramírez Urea - IT Architect, Hoplasoftware
Guillaume Morini - SE, Docker
The integration of Kubernetes orchestration into the Docker Enterprise Platform presents deployments with interesting new abstractions for application connectivity. Devs and Ops 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. We will discuss Kubernetes publishing methods and deep dive into Ingress Controllers. This 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 including going further into limiting traffic to services, session persistence, rewriting, and activating container health checks.
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?
DevOps Days Boston 2017: Real-world Kubernetes for DevOps
DevOps Days Boston 2017
Microservices is an increasingly popular approach to building cloud-native applications. Dozens of new technologies that streamline adopting microservices development such as Docker, Kubernetes, and Envoy have been released over the past few years. But how do you actually use these technologies together to develop, deploy, and run microservices?
In this presentation, we’ll cover the nuances of deploying containerized applications on Kubernetes, including creating a Kubernetes manifest, debugging and logging, and how to build an automated continuous deployment pipeline. Then, we’ll do a brief tour of some of the advanced concepts related to microservices, including service mesh, canary deployments, resilience, and security.
DockerCon 2017: Docker in China
Docker has become extremely popular in China. Since October of 2016, Alibaba Cloud and Docker partnered to drive adoption of containerized applications in China. In this talk, I will share the status for this program and will present the latest survey of container adoption in China. We'll take a deep analysis of the current landscape and what is different about China's market.
In this session, we will also share some use cases for container usage in enterprises - i.e. how Alibaba group build the core business application platform based on scalable container infrastructure and how local enterprises run their business with container technologies in a hybrid cloud environment.
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.

Devoxx 2016 - Docker Nuts and Bolts
Docker is the developer-friendly container technology that enables creation of your application stack: OS, JVM, app server, app, database and all your custom configuration. So you are a Java developer but how comfortable are you and your team taking Docker from development to production? Are you hearing developers say, “But it works on my machine!” when code breaks in production? And if you are, how many hours are then spent standing up an accurate test environment to research and fix the bug that caused the problem?
This workshop/session explains how to package, deploy, and scale Java applications using Docker.

Recent momentum around the evolution of Containers are gradually increase in last two years.Containers virtualize an OS and applications running in each container believe that they have full access to their very own copy of that OS. This is analogous to what VMs do when they virtualize at a lower level, the hardware. In the case of containers, it’s the OS that does the virtualization and maintains the illusion.
Recent past many software companies have quickly adopted container technologies, including Docker Containers, aware of the threat and advantage of the approach. For example, Linux companies have also jumped into the ground, seeing as this as an opportunity to grow the Linux market. Also Microsoft is going to add features to support containers and VMware have made efforts in integrating support for Docker into virtual machine technology.

Using Containers to More Effectively Manage DevOps Continuous Integration
IT organizations can enhance efficiency and cut costs by deploying containers to manage DevOps continuous integration (CI) infrastructure that is self-contained and autonomous.
Building Distributed Systems without Docker, Using Docker Plumbing Projects -...
Docker provides an integrated and opinionated toolset to build, ship and run distributed applications. Over the past year, the Docker codebase has been refactored extensively to extract infrastructure plumbing components that can be used independently, following the UNIX philosophy of small tools doing one thing well: runC, containerd, swarmkit, hyperkit, vpnkit, datakit and the newly introduced InfraKit.
This talk will give an overview of these tools and how you can use them to build your own distributed systems without Docker.

Docker and Cloud - Enables for DevOps - by ACA-IT
DevOps is gericht op het tot stand brengen van een cultuur binnen organisaties waardoor het ontwikkelen, valideren en releasen van software sneller, meer betrouwbaar en frequenter kan verlopen. Om dit te realiseren staan het automatiseren van het 'software delivery process' en de bijhorende infrastructurele veranderingen centraal. Door de opkomst van 'Microservice Architecture' neemt het belang hiervan nog verder toe.
'DOCKER' & CLOUD: ENABLERS For DEVOPS
Sprekers: Stijn Van den Enden & Stijn Wijndaele (ACA IT-Solutions) DevOps is gericht op het tot stand brengen van een cultuur binnen organisaties waardoor het ontwikkelen, valideren en releasen van software sneller, meer betrouwbaar en frequenter kan verlopen. Om dit te realiseren staan het automatiseren van het 'software delivery process' en de bijhorende infrastructurele veranderingen centraal. Door de opkomst van 'Microservice Architecture' neemt het belang hiervan nog verder toe.
In deze avondconferentie werd, na een korte toelichting over DevOps, nagegaan wat Docker en de Cloud kunnen betekenen voor uw business, en hoe zij als enablers kunnen dienen voor het tot stand brengen van een DevOps-cultuur. Het container-landschap waarvan tools zoals Kubernetes, Docker Swarm, ...een belangrijk onderdeel vormen, wordt toegelicht en er wordt ingegaan op de wijze waarop deze tools aangewend kunnen worden om 'development' en 'operations' efficiënt te laten samenwerken.

Everything I found interesting about machines behaving intelligently during May 2024
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Kubernetes in the wild
- 1. Kubernetes in the Wild Building a Content Delivery Network on Kubernetes Daniel Bartholomew, CTO, section.io
- 2. What to expect from this talk Drastic oversimplifications Opinionated statements Errors and omissions Tempting fate - Live code!
- 3. What are we going to cover? Some background on CDN design Some Kubernetes concepts Live Demo using Nginx, Varnish and (maybe) OpenResty
- 4. What makes up a CDN?? 1. Physical Layer: computers, network, global locations 2. Logical Layer: HTTP reverse proxies
- 5. Why would Kubernetes fit this model? Kubernetes provides an elegant framework for running lots of workloads. For CDN, the logical layer.
- 6. Just f’ing hardcode it!!? Most CDNs hardcode specific proxies into their network We think that this reduces architectural options, leading to suboptimal systems
- 7. Focus has shifted CDNs used to provide a big boost just on the physical layer Now CDNs operate more in the logical layer
- 8. Why is that important? Moving to the logical layer started to have effects on the application But the CDN isn’t part of the development environment
- 10. Desired state Provide a CDN that supports: Architecture - freedom of choice Agile - in dev, CI, CD Devops - dev works like prod
- 11. Architectural options Don't hardcode the proxies Provide a library to developers. Choose from caching, security, optimization. Mix and match to suit.
- 12. Agile Provide a source controlled workflow to move code and configuration from development through to production. Assert outcomes along the way.
- 13. The devops thing Provide consistency in process Move CDN from “ops only” to dev Debug production like you do in dev
- 14. Why Kubernetes? Kubernetes provides all the basic components to serve HTTP traffic HTTP Ingress Run HTTP servers inside containers Control linking containers together in the cluster
- 15. Inside the CDN logic layer
- 16. Kubernetes helps the dev workflow Minikube to run on your computer Source controllable Production grade clusters
- 17. Let's build some stuff 1. Get Minikube to proxy traffic for gluecon.com 2. Add Varnish to cache it 3. Add Openresty to alter it
- 18. Step 1: get minikube to proxy some stuff
- 19. Step 2: Add Varnish Cache
- 20. Step 3: Add OpenResty
- 21. Takeaways CDN should not be production only Kubernetes is awesome Most enterprise systems can leverage its awesomeness
