The document discusses the Red Hat Container Development Kit (CDK) designed to assist application developers in building container-based applications using OpenShift. It outlines the features of CDK versions 2.x and 3, emphasizing improved user experience and installation steps in version 3. Additionally, it provides guidance on getting started with container development and accessing the CDK through a no-cost RHEL developer subscription.

3. Environment Differences Have Got to Go
It ain’t 2007 anymore
● Containers have brought the promise of easily deployable standard
runtimes
● But we’re application developers; we don’t *want* to deal with more
layers!

4. The Challenge
Make the container abstractions transparent
● Focus on your business logic
● Use a known build and deployment environment
● Start with continuous delivery and evolve from there

5. Getting Started
Continuous Delivery in the cloud, from the start
● Pick a use case you’re looking to fulfill
● Select your runtime (from RHOAR - Vert.x, WildFly Swarm, Spring
Boot)
● Launch to GitHub and OpenShift Online

6. Red Hat Container Development Kit
(CDK)

7. Red Hat CDK
The value proposition
● Development environment similar to production environment
● Develop/build Microservices, containers
● Same user experience across different operating systems
○ Red Hat Enterprise Linux
○ Microsoft Windows
○ mac OS

8. Red Hat CDK
The objective
Enable application developers to develop container based applications
locally using OpenShift.
● OpenShift as the container platform
● RHEL for running containers

9. For the uninitiated
What is CDK?
CDK provides a local OpenShift Container Platform (OCP) instance on top of
RHEL 7

10. CDK Versions
Little bit of past and present
● CDK 2.4 (Generally available (GA))
● CDK 3 Beta

11. CDK Version 2.x
Components
● A RHEL 7 Vagrant Box for supported hypervisor
● Vagrant plugins
● Vagrant files
Provides
● Openshift container platform instance
● Single node Kubernetes setup

12. CDK Version 3
CDK 3 contains:
● Customized RHEL 7 ISO
● Minishift binary
● OC command line binary
Provides
● Openshift container platform instance

13. What’s New?
In CDK version 3
● Better user experience
● Easier installation steps
○ Just one binary for CDK
● Support for all native hypervisors
○ KVM, Hyper-V, Xhyve and Virtualbox
● Awesomenes!
Note: CDK 3 Beta is available for to use now.

17. Minishift
Upstream project for CDK
● Replaces All-in-one Origin vagrant and Atomic Developer Bundle
● Users have choice between CentOS 7 and Boot2Docker ISO
● Documentation :
https://docs.openshift.org/latest/minishift/index.html
*We released the version 1.0.0 today!*

18. Minishift Quick start
● Install a Minishift supported hypervisor on your operating system
● $ minishift start
Or
● $ minishift start --vm-driver virtualbox
Note: For Xhyve and KVM you need to install an additional driver

19. Minishift
Features
● User can choose OpenShift Origin version
● Addons (i.e. $ minishift addons --help)
○ Anyuid
○ admin-user
● oc-env
● openshift

20. Minishift command line
addons Manages Minishift add-ons
config Modifies Minishift configuration properties.
console Opens or displays the OpenShift Web Console URL.
docker-env Sets Docker environment variables.
hostfolder Manages host folders for use by the OpenShift cluster.
oc-env Sets path of 'oc' binary.
openshift Interact with an Openshift Cluster.
ssh Log in to or run a command on a Minishift VM with SSH.

21. Minishift community
Upstream project for CDK
● In Github: Minishift
● IRC: #minishift (Freenode)

22. Under the hood
Of Minishift project
● Forked from Minikube project
● Uses “oc cluster up” to provision OpenShift
● Uses libmachine to provision the Virtual machine

23. How do I get access to Red Hat CDK?
It is part of no-Cost RHEL developer subscription
● Register in https://developers.redhat.com
● Download it for free.
