How to view images availabe in k8s.gcr.io?

dnx

Going through the Logging lab, I hit an isssue deploying metrics-server, where it looks like the image isn't available:

  Normal   Pulling    20s (x2 over 35s)  kubelet, k8sworker1  Pulling image "k8s.gcr.io/metrics-server:v0.3.7"
  Warning  Failed     18s (x2 over 33s)  kubelet, k8sworker1  Failed to pull image "k8s.gcr.io/metrics-server:v0.3.7": rpc error: code = Unknown desc = Error response from daemon: manifest for k8s.gcr.io/metrics-server:v0.3.7 not found: manifest unknown: Failed to fetch "v0.3.7" from request "/v2/metrics-server/manifests/v0.3.7".
  Warning  Failed     18s (x2 over 33s)  kubelet, k8sworker1  Error: ErrImagePull

I ended up solving the issue by changing branches to release-0.3, but now I'd really like to know how to see which images are avaialble (for any k8s.gcr.io image - be it metrics-server, etcd etc), and I can't actually see a way to do this. If someone knows it'd be really useful.

Hello,

This is an area where there is no set place to find anything really. Following the SIG is a good start. For the metrics server I would look here first: https://github.com/kubernetes-sigs/metrics-server/releases or https://github.com/kubernetes-sigs/metrics-server Looks like 0.3.6 is the latest release today. But really there are so many moving parts and projects it is a constant search pattern and keeping track of multiple blogs/docs pages to see what is happening.

Thanks, I'd hoped there was some sort of interface like docker hub, but release pages and docs it is

You can do this with the GCE cli. I believe it will require credentials to google cloud, which could be a deal-breaker.

gcloud container images list-tags k8s.gcr.io/metrics-server

A site which shows promise of replacing docker hub is Artifact Hub, this may help: https://artifacthub.io/packages/search?page=1&ts_query_web=metrics
