Kubernetes, Helm - helm upgrade fails when config is specified - JupyterHub

If I run

helm upgrade --cleanup-on-fail \
  $RELEASE jupyterhub/jupyterhub \
  --namespace $NAMESPACE \
  --version=0.9.0 \
  --values config.yaml

It fails, with this error: Error: UPGRADE FAILED: pre-upgrade hooks failed: timed out waiting for the condition. It just hangs for a bit and ultimately times out. It seems like too small of a change to cause a true timeout. I found this command in the Zero to JupyterHub docs, where it describes how to apply changes to the configuration file.

I've tried several permutations, including leaving out cleanup, leaving out version, etc. The only thing I could get to work was helm upgrade jhub jupyterhub/jupyterhub, but I don't think it's producing the desired effect.

For example, when I add a line in my config.yaml to change the default to Jupyter Lab, it doesn't work if I run helm upgrade jhub jupyterhub/jupyterhub. I believe I need to specify config.yaml using --values or -f

My overall project is to set up JupyterHub on a cloud Kubernetes environment. I'm using GKE and the online terminal.

Thanks

Solution

  • Solved: I specified tag incorrectly in config.yaml. I put the digest rather than the actual tag. Here are the images on DockerHub
