Looks like I ran out of Kubernetes (ephemeral clusters that is) but the error message isn't very helpful:

ℹ providers                 → [kubernetes] Waiting for resources to be ready...
ℹ providers                 → [kubernetes] Deployment/default-backend: Waiting for rollout: 0 out of 1 new replicas updated...

See .garden/error.log for detailed error message

I can create a GitHub issue but just wanted to check first whether this was known a issue? Or for that matter something unrelated to me being out of minutes?

Did you run into it while creating a cluster? The message should be the error from he API around the lines "Unable to create ephemeral cluster. Your monthly allowed quota has been exhausted" with status code 429, in case your ephemeral clusters quota is exhausted. And core is supposed to show the error message received from API in that case. https://github.com/garden-io/garden/blob/main/core/src/cloud/api.ts#L836

Ok thanks, I'll take another look
