default-repo config set for kube context is ignored

[chris13524]

Expected behavior

I expect skaffold config --kube-context set default-repo to work.

Actual behavior

Configured default-repo for the kube context is ignored and the local-registry-hosting value from the cluster is used instead.

Information

• Skaffold version: 1.38.0
• Operating system: Ubuntu 22.04
• Installed via: skaffold.dev
• Contents of skaffold.yaml:

apiVersion: skaffold/v2beta28
kind: Config
build:
  artifacts:
  - image: nginx
deploy:
  kubectl:
    manifests:
    - deployment.yaml

Dockerfile:

FROM nginx

deployment.yaml:

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx

Steps to reproduce the behavior

1. k3d cluster create --registry-create=test-registry.localhost -p 5000
2. skaffold config --kube-context=k3d-k3s-default set default-repo test-registry.localhost:5000
3. skaffold --kube-context=k3d-k3s-default run

• observe the use of the localhost:xxxx repo name in the image tag rather than test-registry.localhost:5000
• this is the same as the host field from: kubectl --context=k3d-k3s-default get cm -n kube-public local-registry-hosting -o yaml

I think the reason for this is that the default repo is only used from the command line options here. I think if this code block was duplicated for the default repo option, that might work.

If I rename the created context to not have the k3d- prefix in the name, then the configured default-repo works as expected:

kubectl config rename-context k3d-k3s-default k3s-default
