• Make sure you've searched for existing issues, both open and closed
• Make sure you've searched for PRs too, a fix might've been merged already
• You're looking at docs for the released version, "main" branch docs are usually ahead of released versions.

What happened?

I trying to update the air-gapped cluster by creating a new controller and removing the old one. But the old controller generates clusterconfig and lists all the images explicitly, so the new one also tries to use them and fails.

Steps to reproduce

1. Create a cluster with --enable-dynamic-config and --enable-worker, k0s v1.29.* and k0s config like this

  spec:
    images:
      default_pull_policy: Never
    network:
      nodeLocalLoadBalancer: 
        enabled: true

2. Create a new machine with k0s v1.30.* and join the cluster
3. Once the machine joins the cluster it will try to get the old image versions, since they are listed in the dynamic config

Expected behavior

The new machine uses a new images

Actual behavior

The new machine uses old images

Screenshots and logs

No response

Additional context

The reason for this is that we check and strip default values in the config inaccurately:
