Hi! I'm running Rancher on-top of three

k3s

nodes,

k3s

is been started using a couple of flags via

curl -sfL <https://get.k3s.io> | sh -s -

. I would like to create a

config.yaml

and add everything there and restart

k3s

with only the

--config

flag. AFAICT i can change the systemd unit-file and

ExecStart

to add

--config

and do a restart. Any caveats making a change like this?

you don’t need to use the --config flag, the file at /etc/rancher/k3s/config.yaml will be used if it exists as that is the default --config path

just move your flags from the systemd unit to the config file equivalent and restart

Awesome! Thanks for the help!

Related to this question, the first node has the

--cluster-init

flag when started and the two other nodes has

--server

--token

flags set to wire the cluster together. I guess they shall be as-is when changing this to use a config file e.g. the

--cluster-init

flag should be there although the cluster is already up and running?

the cluster-init and server flags are essentially ignored once the node is joined to the etcd cluster.

it’s harmless to leave them there, and you’d need them again if you ever do a cluster-reset/restore though

Sorry for the late answer, thanks for the help!! Everything went well and we managed to switch to a config file instead without any pain.
