Korrel8r as a k8s custom resource with operator

[alanconway]

Define a k8s Custom Resource and operator for korrel8r when running in a cluster.

• korrel8r CR configures list of available stores and domains
• special instance used by openshift console if present. Configured with same stores used by console.
• user instances can connect to other stores

Tenancy:

Korrel8r needs to run with a service account that has permissions to query all the stores that will be used.
Korrel8r clients need the same permissions, to avoid insecure access to data.
Need to determine how best to represent this as k8s roles, many stores with different access rules could get complicated.
