nomad-on-flatcar's Issues

Repo License mismatch

This repo appears to be derived from an upstream MIT-licensed project, at https://github.com/travier/fedora-coreos-nomad.

Upstream project appears to have been archived when HashiCorp switched the license for Nomad from MPL-2.0 to the non-open source BUSL-1.1.

Should we archive this repo?

Drain Nomad node before update

Thanks @iaguis for your presentation at HashiTalks2022!

You mentioned that there is no method to drain a node before an update, similar what the Flatcar Linux Update Operator does on Kubernetes. However, Nomad comes with a CLI command for that, e.g. nomad node drain -enable -self -force -yes force-drains the current node immediately.

This command could probably be run in a systemd service on reboot.target or shutdown.target. When the node is up again, you have to run nomad node drain -disable -self to remove the "drain" flag from the node again.
