# authentik faces the internet (the login for every member of the group),
|
|
# so its pods only reach each other, DNS and the internet: not the LAN
|
|
# (NAS, router) or other namespaces. Scouts Online, the apps' OIDC calls
|
|
# and the LDAP outpost's connection to the server all use public
|
|
# addresses. The worker and the CNPG instance manager also reach the API
|
|
# server (the node, port 16443). Ingress comes from Envoy, the CNPG
|
|
# operator, the node itself (kubelet probes; 10.1.7.64 is the node's
|
|
# Calico VXLAN address, projectcalico.org/IPv4VXLANTunnelAddr), and for
|
|
# the LDAP outpost from anywhere: Stalwart on node001 comes in through the
|
|
# router and the ldap-outpost-external NodePort.
