Skaffold doesn't respect `kube-context` for configuring platform

[anthonyalayo]

Expected behavior

If kubeContext is set in skaffold.yaml, skaffold should use this context to determine the build/deploy platform.

This is what I expect, but it only happens when ~.kube/config's context is matching skaffold.yaml.

DEBU[0000] CLI platforms provided: ""                    subtask=-1 task=DevLoop
DEBU[0000] getting client config for kubeContext: `docker-desktop`  subtask=-1 task=DevLoop
DEBU[0000] platforms detected from active kubernetes cluster nodes: "linux/arm64"  subtask=-1 task=DevLoop
DEBU[0000] platforms selected for artifact "server": "linux/arm64"  subtask=-1 task=DevLoop

Actual behavior

Skaffold will use the current cluster to determine it: https://github.com/GoogleContainerTools/skaffold/blob/51aea28d18210ccc004730db716864283d57e793/pkg/skaffold/platform/resolver.go#L124-L151

This is what actually happens. Skaffold ignores skaffold.yaml and uses the ~.kube/config's context.

DEBU[0001] CLI platforms provided: ""                    subtask=-1 task=DevLoop
DEBU[0001] getting client config for kubeContext: `test-context-amd-64`  subtask=-1 task=DevLoop
DEBU[0001] platforms detected from active kubernetes cluster nodes: "linux/amd64"  subtask=-1 task=DevLoop
DEBU[0001] platforms selected for artifact "server": "linux/amd64"  subtask=-1 task=DevLoop

Notice how it resolved amd64 instead of arm64, which caused issues for me.

Information

• Skaffold version: v2.8.0
• Operating system: macOS Ventura 13.2
• Installed via: homebrew
• Contents of skaffold.yaml:

apiVersion: skaffold/v4beta7
kind: Config
build:
  artifacts:
    - image: test
      docker:
        dockerfile: Dockerfile
  tagPolicy:
    inputDigest: {}
  local:
    push: false
    tryImportMissing: true
deploy:
  kubeContext: docker-desktop

Steps to reproduce the behavior

1. Have 2 kubernetes contexts, one with amd64 and one with arm64
2. Set your current context to the amd64 cluster
3. Set your kubeContext to the arm64 cluster
4. Run skaffold dev

Hey @anthonyalayo, thanks for opening this issue. Have you try the --kube-context flag? Maybe that can help for your use case. It will be something like: skaffold dev --kube-context=docker-desktop. Please let us know! Thanks 😄

@renzodavid9 thanks for the reply! I'm hoping for a solution that can be built into the yaml file, as it is more easier synchronize across developers. Is there an option within the yaml?
