[image-builder-bob]: cannot authenticate against external registries

[mrsimonemms]

When using an external registry, the authentication token is not properly applied. This means that the image builder authentication retries expire, returning a 502 Bad Gateway error to the dashboard logs

To recreate

containerRegistry:
  inCluster: false
  external:
    URL: --URL of registry, eg gcr.io/<project-name>--
    certificate:
      kind: secret
      name: registry-secret

Create the registry-secret using kubectl:

kubectl create secret docker-registry registry-secret ...

Once running, deploy the application to your cluster and start a workspace (one of the example projects are fine)

I have clusters ready and waiting if you want to test/debug
