Hi! I'm starting out with self-hosting. I was setting up Grafana for system monitoring of my mini-PC. However, I ran into issue of keeping credentials secure in my Docker Compose file. I ended up using Docker Swarm since it was the path of least resistance. I've managed to set up Grafana/Prometheus/Node stack and it's working well.

However, before continuing with Docker Swarm, I want to check if this is a good idea or will I potentially dig myself into a corner? Some of the options I've found while searching:

• Continue with Docker Swarm and look into automation of stack/swarm in future

  • Ansible playbook has plugins for Docker Swarm.

• Self-hosted vault: I want to avoid hosting my own secret/password manager at the moment.

• Kubernetes (k8s / k3s) - I don't wanna 😭

  • More seriously, I'm actually learning this for work but don't see the point of implementing it at home. The extra overhead doesn't seem worth it for a single node cluster.

• ~~Live dangerously - Store crdentials in plaintext. Also use admin as password for everything~~

Edit: Most of the services I'm planning on hosting will likely be a single replica service.
