Downtime during Rolling Update #397
Description
Does it make sense for the default value for maxUnavailable to be 1, when the default value for replicas is also 1.
Not many people enjoy having downtime for their DNS server. I think a more reasonable default should be 0 maxUnavailable to eliminate downtime when running 1 instance of pihole. If users can accept downtime during an upgrade they would probably be using the Recreate strategy instead of RollupUpdate.
If my request sounds reasonable, I can open a PR.
