Specifying a Disruption Budget

Pulp operator allows to configure a PodDisruptionBudget for pulpcore components (pulp-api, pulp-content, pulp-worker, pulp-web).

Info

Make sure you know what you are doing before configuring PDB. If not configured correctly it can cause unexpected behavior, like getting a node in a hang state during maintenance (node drain) or cluster upgrade.

It is possible to set only maxUnavailable or minAvailable. Trying to configure both for the same PDB will fail operator execution.

The label selector will be handled by the operator based on Pulp CR spec.

For example, to configure API pods with PDB minAvailable and worker pods with maxUnavailable:

$ oc edit pulp
...
spec:
  api:
    pdb:
      minAvailable: 1
  ...
  worker:
    pdb:
      maxUnavailable: 1
...
