3 ONTAINERIZED APP DEVELOPMENT WITH THE DK

4 4 Today s programme Talk about different ways of containerizing applications Talk about docker, kubernetes and OpenShift Introducing the container development kit a.ka. Minishift Do a sweet, long and hopefully successful demo :) ASK YOUR QUESTIONS ANYTIME! RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

5 ONTAINERIZING APPS

6 6 STIKING YOUR APPS IN A ONTAINER As said, containers hold the promise of making a developer s life easier But: I need to somehow wrap my application in a container There are many ways to take an application and stick it into a container Some examples Using a Dockerfile Using ansible-container reate an image by running docker shell All of these work, but really, as a developer, I really just want to write code... RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

7 7 SOME MORE REQUIREMENTS FROM DEVS As a developer, I want to write code on my local workstation As a developer, I want to be able to functionally test my code on my local workstation before pushing to master As a developer, I want to run integration tests on my code on my local workstation before pushing to master As a developer, I want my development environment to resemble production as much as reasonably possible and still take it home with me RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

8 8 SOME MORE REQUIREMENTS As a freelance developer, I write my code on a Mac, or on Linux As a corporate developer, I need to write my code on a Windows machine As a developer, I want to sometimes use a UI for management of my development environment, and sometimes a LI I want to write my code from Eclipse, like I m used to doing I want to write my code in a uniform way, whatever language I m using I want to benefit from containers, and not have them get in my way Enter OpenShift!

26 THE ONTAINER DEVELOPMENT KIT

27 27 Enter the ontainer Development Kit The DK sets up an OpenShift cluster on your local machine, that allows you to build, test and run your application It offers all the features the OpenShift ontainer Platform brings, like for example: source-to-image pipelines application templates scaling and upgrade tests All supported images that are on the Red Hat ontainer atalog are available! Obviously also runs containers you get from elsewhere :) RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

28 28 The tiniest OpenShift you ever did see! All of OpenShift in a single, small footprint VM using minishift & cluster up All runs from a single binary that is available for Mac, Windows and Linux Supports KVM, VirtualBox, Hyper-V and xhyve as hypervisors During install, an ISO is downloaded, and a containerized version of OpenShift runs on top of that nip.io is used to expose containers to the end-user Official DK 3.0 has been released!

29 LET S TRY SOME STUFF!

30 30 Demo recordings As there were some issues with networking during the presentation on our Tech Day, I made recordings of all demos so you can review them in your own time & at your own pace :) Installing the DK on Windows: Installing the DK on Linux: development on Linux w/ OpenShift & the DK: Java development on Windows w/ OpenShift & the DK: Quickly test small changes with the DK: Playlist: All videos are part of my 100 things to do with Red Hat Management Products channel.

31 31 Red Hat ontainer atalog Go to to get supported, -based container images The whole Red Hat middleware portfolio, language runtimes, and various utilities Health index shows how current ('healthy') an image is We plan to release containers for Vert.x, WildFly Swarm, Spring Boot and node.js soon, as part of Red Hat OpenShift Application Runtimes (RHOAR) RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

32 32 Go get it! Go to Get a free developer subscription, that gives you access to a lot of Red Hat products Download the DK and get going!* * The current version of the DK out there is 2.4. The first minishift-based release will be 3.0, which will be released soon! RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK

33 33 OpenShift Online OpenShift Online has been an ongoing thing since 2011 Originally built upon OpenShift v2 ontainers, but not quite like the ones we use today omplete rewrite done: it s now based on OpenShift v3 Free tier is now available Sign up at RED HAT TEH DAY JUNE MAXIM BURGERHOUT - ONTAINERIZED APP DEV W/ THE DK
