You need to use shred instead of rm. If you use rm the data still lives on your drive until it gets overwritten

Of course high availability always requires multiple nodes.

Its just that while choosing how to set up my cluster I looked up several options (proxmox, swarm, kubernetes…) and I noticed that kubernetes is generally meant for bigger deployments.

I only need a single replica for each of my containers and they can all run on a single node, so kubernetes is overkill just to get high availability For my use case

I was looking into converting my docker services into a cluster to get high availability and to learn it for work, but while investigating it, I read that kubernetes is actually meant for scalability and just a single service per cluster.

Also read that docker swarm is actually what is recommended for my homelab use case. So I’m right now on my way to convert everything to docker stacks. What do you think?
