Explore issues that plague node maintenance and introduce a new API that could be used by various components to solve these issues (e.g. prevent cluster upgrades from being wedged).
- workloads should have more control and a way to react to node maintenance by either removing pods or migrating pods from the maintained node
- workloads should have a way of providing feedback to the cluster admin on the progress of node maintenance
- cluster admin should have a way to identify workloads that are preventing the node drain / cluster-upgrade
- this should take into account the PDB lifecycle, the core workload controllers, but also external components like CRDs and node autoscalers
- the API should allow for customization of the node maintenance process in the future
