Mysql-k8s charm do not work when connected to COS [hook failed: "metrics-endpoint-relation-created"] #504

Closed Barteus closed 2 months ago

Barteus commented 2 months ago

Steps to reproduce

  1. Deploy microk8s
  2. Deploy COS (on the same cluster for simplicity)
  3. juju deploy -m kubeflow --debug ./ckf/bundle.yaml \ --overlay ./ckf/authentication-overlay.yaml \ --overlay ./ckf/cos-integration.yaml \ --overlay ./ckf/mlflow-integration.yaml \ --trust Bundles available here: https://github.com/Barteus/demo-aws-mk8s-ckf-mlflow/tree/dbb19cf294b42ad63d2ed1442a046a7b077f062f/ckf

Expected behavior

Deployment of Kubeflow works and Mysql-k8s charm provide the

Actual behavior

@shayancanonical , for context, I think it's related to PR#483

shayancanonical commented 2 months ago

@paulomach agreed, my suspicion was that the metrics-endpoint-created hook runs before the leader-elected hook is run (thus the cluster-name is unavailable in the app peer databag). since the hook errors out, the queued leader-elected hook is never run

natalytvinova commented 2 months ago

Workaround I found: First deploy without the cos overlay:

juju deploy --overlay auth-overlay.yaml --overlay mlflow-overlay.yaml --overlay storage-overlay.yaml ./kubeflow.yaml --trust -m kubeflow

And when everything settles deploy the overlay:

juju deploy --overlay auth-overlay.yaml --overlay cos-integration-overlay.yaml --overlay mlflow-overlay.yaml --overlay storage-overlay.yaml ./kubeflow.yaml --trust -m kubeflow

And the units come up fine
