Event Details

The Magnum service brings container orchestration to OpenStack, allowing OpenStack users to get a turnkey Kubernetes, Mesos or Docker Swarm cluster set up and ready to host containers with a simple REST call to the Magnum API. At least that would be the case in an ideal world. In our world, the key does not always turn. And if it does, the (Heat) engine driving Magnum may sputter and die. In the first part, we will closely examine the idealized life cycle of a Magnum cluster, from the initial REST call to the point where the user retrieves the access credentials for the finished cluster. We will follow the cluster through Magnum and the OpenStack components involved in building it as it takes shape and examine the roles the individual services play in creating the cluster bit by bit. In the second part we will provide troubleshooting advice on various parts of the cluster creation process that commonly fail. This part will cover both Magnum and Kubernetes related trouble.
