This pull request updates the PostgreSQL host-based authentication (pg_hba) configuration for Patroni to better support common private network ranges used in Kubernetes environments. The main change is a shift from hardcoded network ranges to a more flexible and comprehensive configuration that covers major cloud providers and on-prem setups.
Patroni configuration updates:
In
charts/pmm-ha/values.yaml, thepg_hbaentries underpatroni.dynamicConfiguration.postgresqlhave been updated to allow connections from RFC1918 private networks (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) for bothgfuserandpmmuser, improving compatibility with AWS, GCP, Azure, Docker, minikube, and on-prem environments.In
charts/pmm-ha/charts/pg-db/values.yaml, the previous hardcodedpg_hbaentries for specific subnets have been replaced with an empty list, delegating the configuration to the parent chart and preventing conflicting or redundant settings.
