Demo on how to use Play with OpenShift and a trial to get it working with Jenkins

1. Cloud development
Play, Scala and OpenShift

2. Overview
● It's about OpenShift
● It's not about Play
● It's not about Scala
● There's a hidden agenda
Based on:
https://github.com/opensas/play2-openshift-quickstart#readme

3. Demo 1
● https://openshift.redhat.com
● http://cloudit-xita.rhcloud.com/
● http://brms-xita.rhcloud.com/

4. Available cartridges

5. Let's create CloudIT
● Download Play framework
● Download RedHat Command Line Tools
● Get Play2 OpenShift quickstart
https://github.com/opensas/play2-openshift-quickstart
● Create new Play app "CloudIT"
play new CloudIT
● Initialize git
git init
● Create app on OpenShift (diy)
rhc app create -a cloudit -t diy-0.1 --nogit
● Link git repo's
git remote add origin ssh://uuid@cloudit-xita.rhcloud.com/~/git/cloudit.git/
git pull -s recursive -X theirs origin master
git add .
git commit -m "initial deploy"
git remote add cloudit -m master git://github.com/jdewinne/play2-openshift-quickstart.git
git pull -s recursive -X theirs cloudit master

6. Let's create CloudIT
● Play stage
play clean compile stage
● Add to git
git add .
git commit -m "some first app"
git push origin
● Test
http://cloudit-xita.rhcloud.com/

7. How does it work?
● .openshift/....
● git repo
● Based on standards

8. Let's create CloudIT
● Make some changes
● Add Jenkins
○ Online: enable jenkins
○ Add "play clean compile stage" to build
Use $OPENSHIFT_DATA_DIR
○ Add Play framework to jenkins
Create PLAY environment variable
○ Doesn't work. Why?

9. Pricing & Production use
● Pricing

mailto: openshift@redhat.com
3 applications for free
● Production use
Not yet!

10. OpenShift vs. Heroku
● Create your own PaaS?
● Based on open standards?
● Free for developers?
● Production ready?

13. Next steps
Possibilities:
● Fix Jenkins build
● Create OpenShift Play cartridge
● Add persistence cartridge to demo app
● Put DeployIT on OpenShift
● Arquillian
● Other ideas?
