Recent Docker changes in Fedora

Lokesh, the docker-io package maintainer at Fedora, does a damn good job at keeping it up to date. I think it's a good time to see what changed over the last weeks in the Docker-Fedora world.

WildFly cluster using Docker on Fedora

In my previous blog post I introduced Docker and its Fedora integration. Now it's time to do some serious (read: useful) stuff.

A few years ago I started a project called CirrAS. It's dead now, but the main idea behind it was to form a cluster of JBoss AS servers in the cloud, without any unnecessary steps. You just launched the instances, they found and connected to each other and the result was a working cluster. Additionally every cluster node registered itself in a front-end instance which worked as a load balancer and monitoring/management (we used RHQ) node.
