Supercontroller

Supercontroller is an example controller pattern that can connect to multiple Kubernetes clusters, bulk-operate on entire api group(example.com).

It is-

• Multi-cluster aware
• Multi-resource: will watch all resources in an API group
• Dynamic : doesn't need static schema of resources
• Multi-modal: multiple handlers can be hooked (not sure if this is a good idea)

Use case

Useful for common operations that need to be performed across multiple clusters for an API-group. For example-

• Create a global view in a single datastore
• Process CRs for quota accounting-like use-cases
