The n8n chart (riatlas/chart__n8n) doesn't support startupProbe at all - my earlier fix set a field the chart ignores, so the liveness probe was still killing the container ~40s into startup (exitCode 143, confirmed live via repeated crashloops even after the first 'fix'). n8n takes longer than that to bind :5678 on the VPS's more modest hardware. Widened readiness/liveness directly instead: ~190s total runway before a liveness kill.

# 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, and the app
|
|
# runs continuously too (replicaCount: 1, reachable at
|
|
# n8n.vps.huskypup.net - see manifests/ingress.yaml) - workflow
|
|
# saves/executions will error against the read-only DB until a
|
|
# deliberate manual promotion (flip pg-n8n's spec.replica.enabled to
|
|
# false), but the UI and existing workflow definitions are browsable.
|
|
#
|
|
# 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>

# This chart has no startupProbe support at all (confirmed against
|
|
# `helm show values` - only livenessProbe/readinessProbe exist), so the
|
|
# liveness probe itself has to be generous enough to cover full startup -
|
|
# even home's copied startupProbe timings (60s total) weren't enough on
|
|
# the VPS's more modest hardware; confirmed live it needs 100s+.
|
|
# initialDelaySeconds + (periodSeconds * failureThreshold) = 190s runway.
