Same CNPG replica-cluster pattern as Authentik (continuous WAL replay from home via VPS MinIO, app at 0 replicas until manual promotion - see infrastructure/vps-standby/authentik/manifests/cnpg-cluster.yaml for the full rationale). n8n: N8N_ENCRYPTION_KEY copied byte-identical from home (kubectl, not git) - decrypts stored credentials in the replicated DB, same reasoning as Vault's unseal key / root token copies. Nextcloud: adds infrastructure/vps-standby/nextcloud/manifests/ pvc-restore-cronjob.yaml, the read side of home's existing nextcloud-pvc-sync restic backup - restores the latest snapshot from VPS MinIO into this standby's PVC daily at 04:00 (2h after home's 02:00 backup). No Redis on the VPS side (no redis-operator deployed there, out of scope for a standby that isn't serving traffic - Nextcloud degrades gracefully to DB-based locking without it).

# n8n warm standby on the VPS - Phase 2. Same discipline as
|
|
# infrastructure/vps-standby/authentik/values.yaml: the CNPG replica
|
|
# cluster keeps the DB continuously warm in the background, but the app
|
|
# itself stays at replicaCount: 0 until a deliberate manual promotion
|
|
# (flip pg-n8n's spec.replica.enabled to false, then scale this up).
|
|
#
|
|
# N8N_ENCRYPTION_KEY must be byte-identical to home's - it decrypts
|
|
# stored credentials (API keys, OAuth tokens, etc.) that live encrypted
|
|
# in the DB being replicated. Unlike Authentik's chart-deterministic
|
|
# secret_key, n8n's isn't derived from anything reproducible - it's
|
|
# copied for real (kubectl, not git, same as Vault's unseal key /
|
|
# root token):
|
|
# kubectl -n n8n create secret generic n8n-config-secret \
|
|
# --from-literal=encryption-key=<home's N8N_ENCRYPTION_KEY>
