Red Hat Container Development Kit
For Command Line Developers
About us● CDK developers.
○ Lalatendu Mohanty : @lalatenduM○ Navid Shaikh : @SwordPhilic ○ Praveen Kumar : @kumar_pravin
Contents● Problem statement● Introducing CDK● Use cases● Features● Demo
○ OpenShift○ Kubernetes
● Future Roadmap● Upstream
We are here!● Linux containers are awesome● Use Red Hat Enterprise Linux to run containers● DevOps , Microservices● OpenShift, Kubernetes
Objectives
● Build, run multi-container applications
● Should be same as production environment
● Make enterprise application developer’s life easier
● Should work with Microsoft Windows , OS X, Red Hat Enterprise Linux
Introduction● Prepackaged development environment loaded with production-grade
pre-configured tools.
● Quickly setup development environment for Docker, OpenShift and
Kubernetes.
● Shipped for Microsoft Windows , OS X and Red Hat Enterprise Linux.
● Installer (i.e. development suite) for Windows platform.
Usage Patterns Of CDK● Integrated development environments (IDE)
● Host command line
● “vagrant ssh” and using CDK guest box terminal
Technology pieces used in CDK
● Vagrant
● Vagrant plugins
● Vagrant boxes for Virtualbox, Hyper-V and KVM/Libvirt
Use Cases
OpenShift● Easy and simple way to set up OpenShift Enterprise on developer
workstation.● Same user experience on Windows, Red Hat Enterprise Linux and OS X.● Deploy microservices on workstation.
● Kubernetes master and node configured as single node setup.● Single “vagrant up” command to create the setup.
● Native docker experience for non-Linux platforms.● Works with Eclipse IDE docker tooling.
Let's talk about CDK features
vagrant-service-manager● Acts as a glue between CDK and user’s development environment.● Configures host-based command line for the provided services.● Enables users to configure and use services from CDK.
Vagrant-service-manager command examples$ vagrant service-manager status
$ vagrant service-manager env
$ vagrant service-manager box version
$ vagrant service-manager box ip
$ vagrant service-manager start/stop/restart <service>
Sync-folder with vagrant-sshfs● vagrant-sshfs is the recommended solution for Vagrant’s sync-folder
feature. ● It helps save a developer’s work post “vagrant destroy”.
○ Vagrant guests are ephemeral in nature.
● User’s home directory is mounted inside the guest using SSHFS.○ This enables continuous bi-directional folder sync.
Note: This feature is work-in-progress with respect to the IDE use case.
Nulecule and AtomicAppUsers can develop Nulecule based applications using CDK.
● Nulecule: ○ Specification for packaging a multi-container application.
● AtomicApp: ○ Runtime that understands Nulecule.
○ Works with providers (e.g. Kubernetes, Mesos, OpenShift and Docker) to deploy applications according to Nulecule specification.
● OpenShift2Nulecule:○ Generates Nulecule artifacts from an existing OpenShift application.
Future Roadmap● Landrush integration for easy access to applications deployed in
OpenShift.● vagrant-service-manager improvements for better user experience
○ CLI to install client tools○ CLI to fetch correct Vagrantfiles
● Installers for OS X and Linux

Upstream
Atomic Developer Bundle (ADB)● Upstream project for Red Hat CDK.● Part of CentOS Atomic SIG.● Vagrant box is based on CentOS 7.● Uses OpenShift Origin
Ecosystem Projects● vagrant-service-manager● vagrant-sshfs● adb-vagrant-registration● adb-utils● Landrush● OpenShift2Nulecule
How to participate?● Suggestions , patches, bugs are welcome ! ● Mailing List: [email protected]● IRC Channel: #atomic and #nulecule on Freenode
