fix: missing image for monitoring

[bk201]

Problem:

A new cluster can't be provisioned in an air-gapped environment because the docker.io/rancher/kuberlr-kubectl:v6.0.0 image is missing. Monitoring CRDs is a prerequisite for many charts. The monitoring addon also need this image.

Solution:

Add the image back.

Related Issue(s):

Test plan:

• Ensure a new cluster can run in an air-gapped and non-air-gapped environment.
• Ensure monitoring add on can be enabled and functional.

Additional documentation or context

@w13915984028 I'd keep the v7.0.1 image because it's supposed to be used by Rancher v2.14.0-alpha9.

Pull request overview

Adds a missing Rancher utility image to the repository’s Rancher image allowlist so air-gapped cluster provisioning (and enabling Monitoring/CRDs) doesn’t fail due to an unavailable image.

Changes:

• Add docker.io/rancher/kuberlr-kubectl:v6.0.0 back to the Rancher image list used for image mirroring/air-gap preparation.

thanks for the quick fix!

LGTM, thanks for the fix.

BTW:
On commit 483d831, when bumping rancher-monitoring, this image was set to docker.io/rancher/kuberlr-kubectl:v6.0.0

and due to the image was shared by rancher-monitoring and rancher

it was replaced on later commit b0992d0

Not like the keeping bumping rancher, the rancher-monitoring normally keeps a version for some time.

We need to keep the docker.io/rancher/kuberlr-kubectl:v6.0.0 for rancher-monitoring on v180/master-head, and also keep another version (v7.0.1 for now) which matches embedded Rancher's (v2.14.0-alpha9) usage.

The txt based file seems not easy to comment on some images saying they are locked by some charts :)

I will try to set a used image list on rancher-monitoring addon side, and use a script to check if the expected images are on the list, to avoid such mistake.
