PodDisruptionBudget - Feature request to be managed by Flagger

[AshDerTest]

Describe the feature

Currently with PDB creation, the selector labels are used to determine the pods being monitored. When Flagger deploys the {app.kubernetes.io/name:} is updated to have -primary attached to the end. Is it possible to get Flagger to manage the PDD and create a Primary version.

Proposed solution

Add section in canary yaml in flagger

spec: targetRef: apiVersion: apps/v1 kind: Deployment name: myapp-primary

other configuration options for Flagger

podDisruptionBudget: name: myapp-pdb enabled: true

to monitor and maintain the PDB

Any alternatives you've considered?

• Would require a new set of selector labels (using helm)
• Manul scripts not ideal

Can you describe in more detail your thoughts on this part of the Pod labels change or label selector change in deployment?
