I have been in search for the perfect docker setup for home lab and production environments when Kubernetes doesn't really make sense in every situation. Also, especially for a lot of self-hosted services, many of these do not work well with Kubernetes. Home Assistant is one that comes to mind among others. I have found arguably the best docker container environment in most cases is not Kubernetes, but a Docker Swarm cluster with Microceph installed with distributed storage running CephFS, and Portainer is the management tool that brings it all together. I step you guys through how you can build all of this, including Docker Swarm configuration, CephFS configuration, networking, high availability, and the nuggets of management from the Portainer side.
