--k3s-arg=--disable=... does nothing but --kubernetes-disable still works

[sdemura]

Description

Starting colima with custom --k3s-arg doesn't work.

Using colima start --help example:

colima start --kubernetes --k3s-arg=--disable=coredns,servicelb,traefik,local-storage,metrics-server

colima installs traefik, servicelb, local-path-provisioner (local-storage), metrics-server but does NOT install coredns.

Looking at the source, it looks like --kubernetes-disable is still available but hidden. If I use that version, then colima does the right thing

ex:

colima start --kubernetes --kubernetes-disable=coredns --kubernetes-disable=servicelb --kubernetes-disable=traefik --kubernetes-disa
ble=local-storage --kubernetes-disable=metrics-server

Reproduction Steps

Expected behaviour

colima start --kubernetes --k3s-arg=--disable=coredns,servicelb,traefik,local-storage,metrics-server should actually disable the specified components.

Thanks for reporting, definitely a bug.

This isn't actually really a bug. The issue is with your command. it should be like this since the k3s-arg flag expects multiple strings as values.

colima start --kubernetes --k3s-arg="--disable=coredns,servicelb,traefik,local-storage,metrics-server"

or

Here is my k8s cluster after running it with this command.

It is not a bug. The argument needs to be quoted and it should work as desired.

[sdemura]

Using quotes does not work for me.
