That seems to be it:

$ minikube start
$ skaffold build
<crash>
$ minikube stop
$ skaffold build
<success!>

Should be all good now

@demisx You don’t need to use the docker CLI for passing env vars: https://github.com/haf/skaffold-dockerignore/blob/master/skaffold.yaml#L6-L10 works for me using docker on desktop.

I accidentally reproduced this with @haf’s repro on a separate issue: https://github.com/haf/skaffold-dockerignore - change the skaffold yaml to useDockerCLI: true creates this issue on minikube context, works in non minikube/non-local.

This thread seemed a little to quite so I opened this issue: #2187 and referenced it in the skaffold slack channel: https://kubernetes.slack.com/archives/CABQMSZA6/p1559010140012200. The issue was due to my minikube VM using an old ISO so minikube delete followed by minikube start which downloaded a new ISO solved it for me. @kdkeyser you should try it and see if you get the same results and close the issue. My current settings: OS: ubuntu/amd64 minikube version: v1.1.0 skaffold version: v0.30.0
