[X] I've read the Changelog before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes

To Reproduce

When using a private image for the gha-runner-scale-set runner template, I am getting an ErrImagePull error. The PAT that I am using has the correct permissions but it does not seem to be getting used.

I have changed the values as follows

template:
  spec:
    containers:
      - name: runner
        # image: ghcr.io/actions/actions-runner:latest
        image: ghcr.io/<my-org>/gha-runners:latest
        command: ["/home/runner/run.sh"]

Describe the bug

Getting an image pull error when pulling image. I have tested making the image public and it works but obviously need it to be private. I have also tested pulling images in other deployments using the same key and I do not see the issue.

Describe the expected behavior

Issue is down to the assignment of the secret key for pulling packages.

Additional Context

I have created a kube secrets for the token also, and assigned it in the controller values as follows

imagePullSecrets:
 - name: github-pat

Controller logs show nothing as the worker pods are never launching

@thinkbiggerltd Think you need to add imagePullSecrets to your spec

template:
  spec:
    imagePullSecrets:
      - name: your-secret-name
    containers:
      - name: runner
        image: ghcr.io/<my-org>/gha-runners:latest
        command: ["/home/runner/run.sh"]

Thanks, this worked for me 👍

An update: even though runner pods themselves are coming up with the imagePullSecrets applied, when I set container.image in a workflow, the resulting pod doesn't have imagePullSecrets set
