skaffold: Skaffold v0.23.0 + Windows 10 regression: didn't sync any files

Here’s a workaround that fixes Skaffold Sync at least for me.

Wrap skaffold dev in a script which

• first resets the current namespace,
• starts a subshell in the background that’ll switch back into the namespace you were,
• and runs skaffold dev

_dev() {
  local current_ns; current_ns="$(kubectl config view --minify --output 'jsonpath={..namespace}')"
  kubectl config set-context --current --namespace=
  (sleep 3 && kubectl config set-context --current --namespace="${current_ns}" ) &
    
  skaffold dev
}

You may need to adjust sleep 3 for your environment.

This problem still exists in Skaffold 1.5.0.

Fyi @dgageot here’s the small repro that you asked for.

A workaround is to run skaffold dev with --trigger=polling

Same here, no syncing after the update. Here’s the console output (no error messages):

everything running in the default namespace

Maybe this will be helpful:

Linux environment. I see that problem when my context namespace differ from a namespace defined for Helm chart, for example:

- context:
    cluster: minikube
    namespace: test
    user: minikube
  name: minikube
current-context: minikube

Case 1:

• there is no namespace defined in skaffold.yaml,
• there is test namespace defined in skaffold.yaml Result:
• sync working as expected

Case 2:

• there is namespace defined in Helm Chart with a different name then in context,
• there is staging namespace defined in skaffold.yaml Result:
• sync is not working at all

Where is a bug? Well, probably skaffold do not use proper namespace after deployment to communicate with the cluster?

Workaround: Always change context namespace to a namespace defined in skaffold.yaml or Helm chart before using skaffold.
