“It Works On My Machine”

Environment Differences Have Got to GoIt 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!

The ChallengeMake the container abstractions transparent

● Focus on your business logic● Use a known build and deployment environment● Start with continuous delivery and evolve from there

Getting StartedContinuous 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

Red Hat Container Development Kit (CDK)

Red Hat CDKThe 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

Red Hat CDKThe objective

Enable application developers to develop container based applications locally using OpenShift.● OpenShift as the container platform● RHEL for running containers

For the uninitiatedWhat is CDK?

CDK provides a local OpenShift Container Platform (OCP) instance on top of RHEL 7

CDK VersionsLittle bit of past and present

● CDK 2.4 (Generally available (GA))● CDK 3 Beta

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

CDK Version 3

CDK 3 contains:● Customized RHEL 7 ISO● Minishift binary● OC command line binary

Provides

● Openshift container platform instance

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.

Red Hat OpenShift Application Runtime Demo

Installing launch.openshift.io into MinishiftLaunch new applications, built and deployed by OpenShift, in minutes

● http://appdev.openshift.io/docs/minishift-installation.html

MinishiftUpstream 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!*

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

MinishiftFeatures

● User can choose OpenShift Origin version● Addons (i.e. $ minishift addons --help)

○ Anyuid○ admin-user

● oc-env● openshift

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.

Minishift communityUpstream project for CDK

● In Github: Minishift● IRC: #minishift (Freenode)

Under the hoodOf Minishift project

● Forked from Minikube project● Uses “oc cluster up” to provision OpenShift● Uses libmachine to provision the Virtual machine
