SIGSEGV when pulling schemas in VS Code #3

Closed MPV closed 3 years ago

MPV commented 3 years ago

I'm not able to pull CRD schemas using v0.2.0 of the VS Code plugin.

When I run ytt-lint: Pull crd schemas from Kubernetes cluster, I just get:

Pulling from k8s...
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0x1e7351f]

I.e. from here: https://github.com/SAP/ytt-lint/blob/03765f7e556f8c36a356a2398f86c40098a0113b/pkg/pull/k8s.go#L35

Any ideas?

What kubernetes version are you using? What type of cluster is it (GKE, AKS, Gardener, Azure, minikube)?

phil9909 commented 3 years ago

The latest release v0.2.1 contains a bugfix 36e46cce1ab3615b52d7f1ed41b2efe8425b884b for a missing error check. Because of that bug ytt lint crashes with a SIGSEGV instead of printing a proper error message. Can you try it again and post the real error message?

Tried on a GKE cluster:

Pulling from k8s...
Error: apiextensionsclientset.NewForConfig(): no Auth Provider found for name "gcp"
Exit code: 1

Most of my clusters are GKE clusters, so having this supported would be nice.

Any ideas what might be going wrong?

Let me know if there's anything else I can do to help?

@phil9909 Would you be up for releasing a new version with the fix in 887114e?

phil9909 commented 3 years ago

Just published release v0.2.2 and also uploaded it to Visual Studio Marketplace and Open VSX Registry so you should get an auto-update soon. You can also manually download the VSIX file and then install it using code --install-extension /path/to/extension or codium --install-extension /path/to/extension.
