Overview ¶
Package seedcontrollermanager contains a package for each controller that runs within the seed controller manager binary.
Controllers running in here:
- Must not access master resources like userprojectbindings or usersshkeys
- Must need to access seed resources like the cluster object or the controlplane deployments
- Must not need to access resources within the usercluster like nodes or machines except for cleanup
