Create initial DB and user

1

At the moment I'm using a helm chart to make a job that initialises the cluster once it's up. This feels like a bit of a hack: ```yaml apiVersion: batch/v1...

Supervision strategies and Error Recovery of Graph Actors

There are some external considerations that may lead to a graph actor panicking: persistence DB connectivity problems in particular, which are transient (but we still want to know about them)....

Useful metrics

7

If we're unlucky, the local-path-provisioner can be killed before it has a chance to clean up orphened PVs. These may then hang around while subsequent tests run. Depending on the...

e2e tests racy?

1

It looks to me like it's possible for the `deleteKustomizeDeployment` helper to tear down the local-path-provisioner before it has a chance to clean up associated PVs (with "Delete" reclaim policy)....

provisioner assumes that a node's metadata.name == metadata.labels["kubernetes.io/hostname"]
