manual install rhel8 - how to config file?

[dulhaver]

do to company policies I need to build etcd from source and run it entirely inside of /opt/.

The building is pretty straight forward (doing this inside a podman container based on the Build from Source section in the docs.

My trouble starts when it comes to actually run it. I need a config file, a systemd Service to get this going I assume.

systemd service
looks like there is an example https://github.com/etcd-io/etcd/blob/main/contrib/systemd/etcd.service i'll base this on

config file
can be based on etcd.conf.yml.sample that comes with the build. but ...

• how do I tell etcd to use a config file located in, let's say, /opt/etcd/etcd.conf.yml?
• which values do you really need for it to run from that config?

I think I found a bit of wisdom here

I guess something like ExecStart /opt/etcd/bin/etcd --config-file /opt/etcd/etcd.conf.yml in the sydemd unitfile, might be the direction to go
