Description

https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.18/#affinity-v1-core

orch -> k8s

from kubernetes.client import V1Affinity
def placement_spec_to_k8s(spec: PlacementSpec) -> Tuple[int, V1Affinity]: 
    """ 
    - node list
    - labels
    - count (?)
    - all nodes?
    - host glob?
"""

k8s Rook CR -> orch:

  1. parse any CR we generated fro generate_k8s_placement()
  2. show when we don't understand the placement
    ceph orch ls should say "<opaque>" or "?" if we can't parse it
  3. maybe parse other common CRs (e.g., ones from rook examples dir)

Anything that can be added to the PlacementSpec which is often used by Rook?
