This works only on Openshift Console V2 (Legacy)

openshift-craftbukkit-quickstart

A quickstart Minecraft (Craftbukkit) server that will automatically download latest craftbukkit development build and start it.

Create the Openshift DIY Application

1. Create a DIY application using this git repo as source code:

   $ rhc app-create craftbukkit diy --from-code=git://github.com/golyalpha/openshift-craftbukkit-quickstart.git

2. Create a port-forward from your local machine to your remote server:

   $ rhc port-forward craftbukkit
   Checking available ports ... done
   Forwarding ports ...
   
   To connect to a service running on OpenShift, use the Local address
   
   Service Local                OpenShift
   ------- --------------- ---- ---------
   java    127.0.0.1:25565  =>  *:25565
   
   Press CTRL-C to terminate port forwarding

3. The server will be accessible from minecraft using Direct Connect on 127.0.0.1:25565

Setting Administrative Player (Op)

You will need at least one player to act as the administrator. In order to do that, you must add them through server console.

1. SSH to the application:

   $ rhc ssh

2. Stop gear, go to openshift data dir and run server:

   $ gear stop
   $ cd $OPENSHIFT_DATA_DIR
   $ java -jar CraftBukkit.jar

3. In server console op someone.

   > op <player>

4. Stop server and start the gear.

   > stop
   $ gear start
   Starting gear...
