cannot use $patch: delete for machine patches

[clementnuss]

hi,

I'm trying to remove the exclude-from-load-balancer label from my control-plane nodes, but am getting an error:

patch:

controlPlane:
  patches:
    - |-
      machine:
        nodeLabels:
          node.kubernetes.io/exclude-from-external-load-balancers:
            $patch: delete

error:

2025/03/03 07:01:06 failed to parse config file: failed to substitute env: variable ${patch} not set

is there any way to add a skipEnvSubst arg somehow ?

Hi!

You're using patches wrong. It should be something like this:

controlPlane:
  patches:
    - |-
       - op: remove
         path: /machine/nodeLabels/node.kubernetes.io~1exclude-from-external-load-balancers
         value: the-value

But then, I think it's not there by default so it means you added it, why not just don't add it? Sorry if I misunderstood you, I'm really confused here.
