# External Secrets' three pods reach each other, DNS and the API server
|
|
# (the node, port 16443); the controller also reads Vault
|
|
# (vault-active.vault.svc:8200, which vault/networkpolicy.yaml lets it
|
|
# into). Besides their own namespace they take connections only from the
|
|
# node: the API server calls the webhook 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 Password generator behind
|
|
# gatus/backup-check-token needs no network. The chart's Application
|
|
# (apps/templates/external-secrets-helm.yaml) only installs the chart, so
|
|
# this folder gets an Application of its own, external-secrets-folder.
