Docker - Build, Ship and Run Any App, Anywhere Hollywood edition

Do you know the performance of your containers or Docker Hosts? I will show you how to get up and running quickly with 2 different Open Source Docker Monitoring solutions. We will quickly cover Docker Stats as the basis and discover how Google cAdvisor gathers metrics for our 2 solutions. We will then build upon this basis to build a Docker Monitoring solution with cAdvisor+InfluxDB+Grafana and then cAdvisor+Prometheus and create dashboards based on the gathered monitoring metrics with Grafna and Prometheus.

Containers: Life Beyond Microservices? by Sushil Kumar, Robin Systems

Docker, Inc.

Docker and microservices architecture have taken the software community by storm. Containerizing stateless applications is a no-brainer, but how about performance-sensitive stateful apps like databases and Hadoop? Must you compromise on performance and predictability for the love of containers? In this session we will discuss how the full-application-stack-containerization is not only possible, there are actually lots of advantages to it. We will also talk about how to build a pure-container infrastructure platform that can help containerize both your stateless and stateful apps, deliver guaranteed app-to-spindle performance, and bring agile DevOps practices to data.

Docker Birthday App key feature improvements: - A haproxy load balancer, based on the dockercloud/haproxy image, for dynamic configuration. - Dockerized the locust load testing framework, in order to create fake http requests to the voting page. - Autoscaling of the voting-app and worker containers. Using the docker remote API, I monitor the CPU usage of the two containers and scale up or down, depending on the threshold. The bottom threshold is 5% and the upper at 30%.

Docker, Inc.

How do you bring a NoSQL DB into a production Docker Environment? What are key orchestration challenges? How can you design a portable solution that can lift and shift into any environment? What are pro’s and con’s to containerizing your database? By establishing a set of best practices and proper testing you can ensure that your infrastructure design can be resilient in any global environment. The challenge is identifying what works best for your organization. Disruptive testing and partnering with other teams within your company can ensure success when implementing a global application. In this session you will learn from a member of MetLife’s ModSquad innovation team firsthand what challenges MetLife overcame using a NoSQL DB in a Docker environment. You will learn about key decisions impacting orchestration, availability, database replication, and disaster recovery. Additionally, you will understand key differences in classic and swarm mode and how Kubernetes and Docker teaming up will help your Production Design.

20 mins to Faking the DevOps Unicorn by Matt williams, Datadog

Docker, Inc.

Something changed in job ads over the last few years: everyone wants the DevOps Unicorn. What is that and why did this happen? You probably have a good amount of what is in that description, but is there an easy way to fill in the rest of the 100%? It turns out that it is possible to fake your way to being a DevOps Unicorn. All that you need is a way to know which metrics are the most important. And to know that you need a framework that applies everywhere. No really, it's easier than you think. There is some work needed on your part, but just a few minutes is enough to get started. In this 20 minute session, we will cover what changed in the market, what the framework looks like, and how to apply it to all of the containerized applications you need to monitor.

OSDC 2018 | Ops hates containers. Why? by Martin Alfke

NETWAYS

“Docker, Docker, Docker, Docker,…” developers really love Docker. Usually one sees the no longer need for configuration management, the easy way to spin up a platform on a laptop, the low resource footprint. But how do you deploy laptops in data centers? This talk will give you an insight how we (more Ops then Dev) started to learn (and love) containers, the issues we saw when running them in larger scale and how Ops people should start dealing with Container technologies.

Cost Control Across Cloud, On-Premise and VM Computers by Mark Lavi, Calm.io

Docker, Inc.

Anecdotal numbers suggest that more than 40% compute resources are under utilized -- from unused cloud instances to virtual machines running on bare-metal. Hundreds of QA & Dev nodes to thousands of production instances could be shutdown, and brought back to the same state on demand. That's what cloud is about -- agility and efficiency, but our on-premise datacenter habits have migrated to the cloud as well. Calm's DevOps automation platform helps fix our old habits. Calm provides a single pane of glass across cloud and on-premise, integrating with Chef, Puppet and Docker ecosystems. The single pane of glass enables orchestration, cost-control and on-demand provisioning.

Cloud foundry: The Platform for Forging Cloud Native Applications

Chip Childers

It wasn’t too long ago that artisans, bathed in the glow of molten metal, forged parts that would go on to make up bigger, more powerful machines. Today, we call those artisans developers. Instead of metal, they use bits and bytes in the cloud to forge a modern application architecture that supports public, private and hybrid application deployment. One that enables users and developers to move their applications wherever they need to go. And it’s built on a growing, vibrant ecosystem. Nowhere is this epic shift in how things are made more visible than the meteoric adoption of Cloud Foundry. In this talk, Chip Childers, VP of Technology for Cloud Foundry Foundation, will give attendees an inside look at the industry movements and the technological requirements that are driving Cloud Foundry's rapid adoption. Most importantly, he will walk through how organizations are responding to the challenge of continuous innovation, what's driving modern application architectures, and how the Cloud Foundry platform uses specific constraints in order to fulfill it's promise to application owners.

Lors de cette présentation, nous allons dans un premier temps rappeler la spécificité de docker par rapport à une VM (PID, cgroups, etc) parler du système de layer et de la différence entre images et instances puis nous présenterons succinctement kubernetes. Ensuite, nous présenterons un processus « standard » de propagation d’une version CI/CD (développement, préproduction, production) à travers les tags docker. Enfin, nous parlerons des différents composants constituant une application docker (base-image, tooling, librairie, code). Une fois cette introduction réalisée, nous parlerons du cycle de vie d’une application à travers ses phases de développement, BAU pour mettre en avant que les failles de sécurité en période de développement sont rapidement corrigées par de nouvelles releases, mais pas nécessairement en BAU où les releases sont plus rares. Nous parlerons des diverses solutions (jfrog Xray, clair, …) pour le suivie des automatique des CVE et l’automatisation des mises à jour. Enfin, nous ferons un bref retour d’expérience pour parler des difficultés rencontrées et des propositions d’organisation mises en oeuvre. Cette présentation bien qu’illustrée par des implémentations techniques et très organisationnel

Shipping Applications to Production in Containers with Docker

Jérôme Petazzoni

Docker is an Open Source engine to build, run, and manage Linux Containers. Containers use less resources than virtual machines, they boot faster, but they have similar guarantees of portability and repeatability for Linux applications. Those features made Docker and Linux Containers extremely popular for development and testing environments. But what does it take to use Docker and Containers for production workloads?

A Gentle Introduction To Docker And All Things Containers

Jérôme Petazzoni

Docker is a runtime for Linux Containers. It enables "separation of concern" between devs and ops, and solves the "matrix from hell" of software deployment. This presentation explains it all! It also explains the role of the storage backend and compares the various backends available. It gives multiple recipes to build Docker images, including integration with configuration management software like Chef, Puppet, Salt, Ansible. If you already watched other Docker presentations, this is an actualized version (as of mid-November 2013) of the thing!

Introduction to Docker - 2017

Docker, Inc.

Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps.

Docker?!?! But I'm a SysAdmin

Docker, Inc.

Your developers just walked into your cube and said: "Here's the new app, I built it with Docker, and it's ready to go live." What do you do next? In this session, we'll talk about what containers are and what they are not. And we'll step through a series of considerations that need to be examined when deploying containerized workloads - VMs or Container? Bare Metal or Cloud? What about capacity planning? Security? Disaster Recovery? How do I even get started?
