Why use openshift.redhat.com?

It's a great way to collaborate

– Uses git for version control

– Access Openshift from any machine, home/work

– Share an Openshift account with your team

It's cheap

– Compared to shared hosting service eg. GoDaddy

– Compared to hosting your own Infrastructure

Create JEE apps

– Uses EAP 6

How do I update an application?

Use the 'jboss-tools' plugin for Eclipse, or JBDS

Push your changes to the Openshift git repo

Use Jenkins to run your test suite before deploying

https://github.com/openshift/crankcase/tree/master/cartridges/jbossas-7/template

Edit the Server config in git repo file:

How Does it work?

Cartridge – An extensible and stackable method of adding functionality to the underlying platform

– Frameworks/Languages

– Datasources

Broker – Single Point of contact for application management

– Use CLI/ Eclipse / Webapp to contact

– User logins / DNS / Application state

How Does it work?

Gear

– Resource constrained container to run cartridges.

– Limits the amount of RAM/CPU available to cartridges

Node

– Enable sharing of resources

– Multiple gears per node

– Generally one per server or virtual machine
