Converting from Kubernetes to Docker Swarm |

Sometimes, it's nice to scale down the homelab to something a little simpler. |
After an irrecoverable k3s failure on my pi cluster, I've chosen to simplify my homelab to a basic docker swarm cluster today. I learned what I wanted - and the level of debugging required to sort out why my servers wouldn’t come up was a little too much like my day job, and not enough of an experimental sandbox.
I just don't need 7 containers to orchestrate a deployments to a pi cluster.
As automated as thek3sup tool is for setting up clusters, they didn't bother
to automate any teardown and cleanup. Fortunately, k3s includes scripts for these
as part of the install.
On the server node, you can run the following script:
/usr/local/bin/k3s-uninstall.shAnd on your agents nodes, the script name is slightly different:
/usr/local/bin/k3s-agent-uninstall.shAnd that's it! Kubernetes has been cleaned up, and your servers are ready for whatever's next.
