ERROR:: no kubeconfig file found try adding one at $HOME/.kube/config

[flobaader]

After introducing projects in v0.5.0 acorn throws this error on my GitLab CI Pipeline.

✗  ERROR:: no kubeconfig file found try adding one at $HOME/.kube/config

I created a project locally using acorn project create test and I am then using the -j option in the CI pipeline.

The pipeline:

acorn build -j test -t $IMAGE --push .
acorn run --update -j test -n $CI_ENVIRONMENT_SLUG $IMAGE

The build runs fine every time, the run command throws the No Kubeconfig exception

Workaround:
When deleting and re-creating the project, the next pipeline passes.

This is the debug output:

✗  ERROR:: no kubeconfig file found try adding one at $HOME/.kube/config

What I find the most confusing is that it loads a config file in the first line, but then complains that the kube file has not been found. I suppose that this happens on the kubernetes server side or so.

For comparison, this is the debug log when the pipelines passes successfully:

Cleaning up project directory and file based variables

[flobaader]

Update: This also happens, when the Gitlab Kubernetes Proxy is not used and acorn has direct cluster access.
The first deployment to a project succeeds, the second deploy to a project always fails.

[sangee2004]

KUBECONFIG set (No config file in ~/.kube/ and no config.yaml for acorn (~/.config/acorn/) )

Able to reproduce the problem in 0.5.0 (acorn version v0.5.0+7a4904c7) using the following steps:

acorn project create test3
acorn run -n test1 -j test3 .
acorn run --update -n test1 -j test3 .
` ✗  ERROR:  no kubeconfig file found try adding one at $HOME/.kube/config`

This issue is not reproducible when testing with v0.5.0-35-g0f895e7+0f895e74

acorn project create test3
acorn run -n test1 -j test3 .
acorn run --update -n test1 -j test3 . ==> succeeds. Able to update existing apps multiple times without any issues.

@flobaader Fix for this issue will be made available in v0.5.1 release. Please reopen this issue if the issue still exists for you when testing with v0.5.1 release
