Should I stick with Docker Swarm for self-hosting? (lemmy.world)

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.

I was in the same place as you a few years ago - I liked swarm, and was a bit intimidated by kubernetes - so I'd encourage you to take a stab at kubernetes. Everything you like about swam kubernetes does better, and tools like k3s make it super simple to get set up. There _is& a learning curve, but I'd say it's worth it. Swarm is more or less a dead end tech at this point, and there are a lot more resources about kubernetes out there.
