It would be nice to be able to define a default PDB tho. I’m not exactly sure of the default behavior but I often have new tenants forget PDB and then have outages during the first node pool upgrade.
I vaguely recall a proposal for that. I'll look/inquire. In the meantime, the main focus is GA/stable: https://github.com/kubernetes/enhancements/blob/6f42c8560c2c36fde3730fcb0d882b2451cdc00d/keps/sig-apps/20190318-PodDisruptionBudget-graduation-to-stable.md …

There’s a gotcha there by
@davidopp, using principle of least surprise to rationalize not surprising the expert that knows PDBs exist and how they work. Better to avoid surprising the non-expert who doesn’t know Kubernetes well. There are vastly more of them. - Show replies
