Many of the posts I read here are about Docker. Is anybody using Kubernetes to manage their self hosted stuff? For those who’ve tried it and went back to Docker, why?
I’m doing my 3rd rebuild of a K8s cluster after learning things that I’ve done wrong and wanted to start fresh, but when enhancing my Docker setup and deciding between K8s and Docker Swarm, I decided on K8s for the learning opportunities and how it could help me at work.
What’s your story?

Kubernetes is useful if you have gone full cattle over pets. And that is very uncommon in home setups. If you only own one or two small machines you cannot destroy infra easily in a “cattle” way, and the bloatware that comes with Kubernetes doesn’t help you neither.
In homelabs and home servers the pros of Kubernetes are not very useful: high availability, auto-scaling, gitops integrations, etc: Why would you need autoscaling and HA for a SFTP used only by you? Instead you write a docker-compose.yml and call it a day.
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?
I’m not sure what you mean by that.
It provides high availability if you have multiple nodes and pods.
Also what do you mean by single service per cluster? Because that’s not the idea at all.
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
