# The CloudNativePG operator reaches DNS, the API server (the node, port
|
|
# 16443) and the PostgreSQL instances it runs in other namespaces: the
|
|
# instance manager's status port (8000) and PostgreSQL (5432), which the
|
|
# instances' own policies let in (postgres-cnpg in authentik and immich).
|
|
# Besides its own namespace it takes connections only from the node: the
|
|
# API server calls its webhook (9443) from there and the kubelet probes
|
|
# come from there too (10.1.7.64 is the node's Calico VXLAN address,
|
|
# projectcalico.org/IPv4VXLANTunnelAddr). The chart's Application
|
|
# (apps/templates/cloudnativepg-helm.yaml) only installs the chart, so
|
|
# this folder gets an Application of its own, cloudnative-pg-folder.
