Configuration management

With every system that depends on a large number of similarly configured machines (regardless of whether they are physical or virtual ones), there always arises a need for simple and easy rebuild tooling to help automate the majority of the tasks that have in the past been done by hand. In the case of PaaS clusters, ideally, all pieces of the infrastructure are capable of being rebuilt with minimal user intervention into the exact state that is wanted. In the case of bare-metal PaaS server nodes, this is critically important as any operation that you have to do manually gets multiplied by the number of nodes you have, so streamlining this process should be of utmost importance for any kind of production-ready clustering infrastructure.

Now you may ask yourself, "Why do we care about covering CM tooling?" and the truth of the matter is that if you do not have proper CM around your container infrastructure, you are guaranteeing yourself after-hour emergency calls due...
