Beschreibung

I'm using Skaffold with a Kaniko build step on GKE and am wondering why the need for the kaniko-secret.

If I'm in GKE and the default SA used has permissions to push to my GCR repo why do I need to also supply SA keys via the kaniko-secret?

I see that things are working without the secret if Workload Identity is enabled but what about clusters not yet migrated to Workload Identity? https://github.com/GoogleContainerTools/skaffold/issues/3468

The only way I found to get it working is with the following instructions and skaffold.yaml.

Instructions:

  1. Create SA with Starage Admin
  2. Download keys
  3. Rename keys to kaniko-secret
  4. kubectl create secret generic kaniko-secret --from-file=kaniko-secret

skaffold.yaml

apiVersion: skaffold/v2beta7
kind: Config
metadata:
  name: my-image
build:
  artifacts:
    - image: gcr.io/my-repo/my-image
      kaniko:
        cache: {}
  cluster:
    pullSecretName: kaniko-secret

How can I make this work with the default SA and not have to add secondary keys?
