Answer 1

You are using wrong API version.

Look at the skaffold.yaml reference page - you can see there proper apiVersion examples:

apiVersion: skaffold/v2beta10 
apiVersion: skaffold/v2beta9
apiVersion: skaffold/v2alpha1
etc

Even if you use Skaffold v0.25.0 Release - 3/15/2019, there is a note that fix your problem.

Note: This release comes with a new config version v1beta7. To upgrade your skaffold.yaml, use skaffold fix. If you don't upgrade, skaffold will auto-upgrade in memory as best it can, and print a warning message.

So using apiVersion: skaffold/v1beta7 should help
