First step from 1.11.2 to 1.13 now that the cluster runs Kubernetes 1.35. The internal NetworkPolicies that 1.12 enables by default stay off: Calico would enforce them, and the instance-manager policy only admits Longhorn pods while the iSCSI initiator connects from the host.
Also lifts the Renovate hold below 1.11.3, which only existed for Kubernetes 1.33.
Envoy Gateway v1.9 needs Kubernetes 1.33, and microk8s 1.32 is out of
upstream support. docs/upgrade-k8s-1.33.md lists what has to move first
and in which order. Renovate is held below Longhorn 1.11.3, since that
and newer releases need Kubernetes 1.34.
Add ntfy at ntfy2.rubenhensen.nl on the home cluster, pointed straight at
the home IP like s2. s2 now alerts on mail and on s1 through it. The
home services are left to s1, which sees them from outside.
ntfy denies everything except the provisioned user. The user, its
password hash and the Gatus token come from Vault kv/ntfy.
Gatus with sqlite history, checking every public service plus its twin
s1.rubenhensen.nl on Hetzner. Replaces the GitHub-hosted Upptime page.
DNS gets s1 (Hetzner) and s2. s2 points straight at the home IP rather
than through the Hetzner tunnel, so it stays reachable when Hetzner is
down.
gatus/README.md explains how to read the two pages and writes down the
plan for a single self-hosted failover URL (PowerDNS LUA records).
Deploys ghcr.io/rubenhensen/bolletjestrui at vic.rubenhensen.nl:
- bolletjestrui/ folder: deployment (SQLite on a PVC, migrate-on-start,
ORIGIN + raised BODY_SIZE_LIMIT for GPX uploads), service, nginx
ingress with prod-cluster-issuer TLS, PVC, and a Vault ExternalSecret
(kv/bolletjestrui: site_password, admin_password, key_secret).
- apps/templates/bolletjestrui-folder.yaml: ArgoCD Application.
- dns: vic A record -> 46.224.26.65 (ingress LB).
- renovate: watch bolletjestrui/ for image tag bumps.
Committed locally, not pushed: needs the Vault secret created and the
ghcr package made public first.
