Wondering how to disable traefik and helm addon on my existing cluster

For example, to disable traefik from being installed on a new cluster, or to uninstall it and remove the manifest from an existing cluster, you can start K3s with

--disable=traefik

. Multiple items can be disabled by separating their names with commas, or by repeating the flag.

From this document, does using

--disable=traefik

arg from the server start cmd also works the same? or it needs to be from installation cmd?

Hello Giovan! Rerunning the install script and adding such flags should do the trick.

I do not believe it needs to be done from the install script. I have k3s installed without using the install script. My

/etc/rancher/k3s/config.yaml

file on my master contains:

disable:
  - traefik

That is read when the server/master starts. You could put it on the command line of the server too. However if you have already started the server with traefik, I do not know if there are any resources that would now need to be cleaned up.

Yes, that should do the trick too! (I prefer to set them in configuration file too)
