Cluster status error since 0.33.9 with eks cluster

[brian-bk]

Expected Behavior

Tilt should be able to connect to the cluster on tilt up etc.

Current Behavior

Tilt is unable to connect to the cluster directly. We still see tilt managing local_resources and our Tiltfile executes some kubectl commands manually via local or local_resource, but the managed k8s resources behind a helm_resource do not work. In addition after the Tiltfile processing finishes there's a noted failure on the (Tiltfile) resource.

Successfully loaded Tiltfile (1m14.658932792s)
Cluster status error: Tilt encountered an error connecting to your Kubernetes cluster:
    Get "[https://<redacted>.gr7.us-east-1.eks.amazonaws.com/version?timeout=32s":](https://<redacted>.gr7.us-east-1.eks.amazonaws.com/version?timeout=32s%22:) context deadline exceeded
You will need to restart Tilt after resolving the issue.

We have tested and in 0.33.8 this works without such issue, and I tested with 0.33.15 and the issue since 0.33.9 still persists.

Steps to Reproduce

1. Configure an eks cluster and authenticate against it
2. Run tilt up
3. Wait for resources to load, but then tilt cannot connect to the cluster even while kubectl commands from inside a local or local_resource resources work

About Your Use Case

This has been happening since 0.33.9 and I forgot to report it right away. This still happens on 0.33.15. For now we've actually added a check in our Tiltfile to force people on to <=0.33.8, until this can be resolved. Maybe it's specific to Amazon EKS's authentication, but I'm not sure.

[nicks]

Hmmm...I tried this with my own EKS cluster, and was not able to repro.

I went through all the changes between 0.33.8 and 0.33.9 and didn't see any changes that would affect how tilt computes cluster status.

[nicks]

can you post the output of:

kubectl get -v=6 --raw /version

?

[brian-bk]

Sure thing

$ kubectl get -v=6 --raw /version

🤷 don't know if relevant or not but I (and most of our engineers) are using arm64, with a amd64 cluster.
