This document discusses developer workflows using Docker from development to production. It covers using Docker Compose and Docker Swarm for local development and Docker Cloud for managing production deployments. It also discusses using Kubernetes and cloud native PaaS solutions like Deis, OpenShift, and Rancher that are based on Kubernetes. Specifically, it demos deploying a sample application to OpenShift using the Red Hat Container Development Kit.

1. Developer Workflow with
Docker
From Development to Production

2. Disclaimer
I am not trying to create a generalized workflow for all application developers. The
idea is to give an overview of available solutions.

● Lalatendu Mohanty
● @lalatenduM on Twitter.
● lalatenduM on Freenode.
● Homepage/Blogs : lalatendu.org
● Working for Red Hat as a software engineer.

4. Things I am trying to cover in this talk
● Opinionated workflow for Kubernetes and Docker Compose/Swarm.
● As I have just 30 minutes for the presentation, I will only demo one project
from each Kubernetes and Docker Compose/Swarm ecosystem.
Note: Pivotal Cloud Foundry is absent in this the talk as they do not directly use Kubernetes or Docker
Compose/Swarm.

5. Docker Compose Ecosystem
● Docker Toolbox (For Non-Linux/GNU OS)
○ Docker Compose
○ Docker Swarm
● Linux/GNU distributions have native support.
● Managing Production deployments.
○ Docker Cloud
○ Rancher 1.0
Note : Due to lack to time I am going to talk about Docker Cloud in this presentation.

6. Docker Cloud

7. Docker Cloud Salient Features
● Unified Interface for managing containers on public cloud and privately hosted
machines
● Integration with Docker Compose and Docker Swarm.
● Integration with Docker Hub (public and private repositories)
● Security scanning in Docker Cloud

8. Docker Cloud Live Demo

9. Kubernetes
● Automating deployment, scaling, and management of containerized
applications.
● Various ways to set up local development environment e.g. minikube,
kmachine, Red Hat CDK.

10. Why PaaS?
● Complete lifecycle management of application.
● Developers can deploy application without help from operation team.
● Stable and transparent developer workflow.
● Supports the idea of continuous deployment (DevOps).

11. Cloud Native Paas Based On Kubernetes
● Deis
○ Deis builds upon Docker and CoreOS to provide a lightweight Paas.
● OpenShift
○ Uses Docker and Kubernetes and builds on top of it.
● Kel
All of the above Paas solutions are open source. Both Deis and OpenShift
supports both private and public Clouds.
● Rancher 1.0 also have a nice interface and tooling to deploy containers on a Kubernetes cluster.
● There are Kubernetes support in Public clouds too.

12. OpenShift
● Local development environment through ADB/CDK
○ ADB : Atomic Developer Bundle.
○ CDK: Container Development Kit.
● OpenShift Online.
● OpenShift Origin.
● OpenShift Dedicated.

13. OpenShift
● Automates application builds, deployments, scaling, health management and
more.
● Developers have the choice and the ability to run multiple languages,
frameworks, and databases on the same platform.
● It is a self service platform for application developers.
● Runs on top of physical or virtual, public or private cloud, and even hybrid
cloud infrastructure.
● OpenShift dedicated for deploying/running it on public cloud e.g. AWS and
Google Compute Engine.
● Suited for running micro-services kind of applications.

14. OpenShift Salient Features
● Uses Kubernetes orchestration, management and Docker as the container
technology.
● Automated image builds and promotion.
● Deployments integrated with builds and CI.
● Source to image build process.
● Integrated networking (SDN, DNS, routing) for container networking.
● Fully integrated Docker registry.
● Integrate with Docker Hub and other 3rd party enterprises registries.
● Support for persistent volumes with various cloud storage solutions.
● Integrated enterprise features e.g authentication (LDAP etc), quota etc.

15. OpenShift Architecture

16. OpenShift Demo On CDK

17. Red Hat Container Development Kit 2.0
● Development environment same as the production environment.
● Easiest way to setup OpenShift.
○ One command to set up/destroy i.e. “vagrant up” roy" and “vagrant destroy”
○ There are templates of sample applications.
● Quickly get single node Kubernetes setup or Docker run time Windows, OS X,
Linux/GNU.
● Overview: http://developers.redhat.com/products/cdk/overview/
● The upstream project of CDK is called Atomic Developer Bundle.

18. How to get CDK?
● Sign up for developer.redhat.com.
● Follow: http://developers.redhat.com/products/cdk/get-started/

19. Atomic Developer Bundle
● Upstream community project of Red Hat Container Development Kit.
● Helps to create developer environment for Docker, OpenShift Origin,
Kubernetes, Mesos Marathon.
● Github Url: https://github.com/projectatomic/adb-atomic-developer-bundle.
