In the previous blog post, we have looked into the multi-host networking capabilities with Docker with native network and Calico. In this blog post, our journey to make Galera Cluster run smoothly on Docker containers continues. Deploying Galera Cluster on Docker is tricky when using orchestration tools. Due to the nature of the scheduler in container orchestration tools and the assumption of homogenous images, the scheduler will just fire the respective containers according to the run command and leave the bootstrapping process to the container’s entrypoint logic when starting up. And you do not want to do that for Galera - starting all nodes at once means each node will form a “1-node cluster” and you’ll end up with a disjointed system.
