Single instance and PDB #233

Closed gitarns closed 6 months ago

gitarns commented 6 months ago

Hello,

When we create a single instance "Cluster", the operator adds a pdb with a minimum pod of one, making the pg pod immune to eviction.

Is there a configuration to disable the creation of the pdb ?

Not as far as I am aware. This is a design feature of the operator to ensure that at least one database pod is always available, including during maintenance windows and node drains.
