Update the baseline to treat Rancher backup and restore validation as part
of the accepted platform state, and capture the successful live drill run
performed on 2026-04-18.
Add a post-deploy smoke test that validates Tailscale DNS, proxy readiness,
reachability, and service responses for Rancher, Grafana, and Prometheus.
Move the operator to the stable Helm repo/version and align the baseline docs
with the current HA private-only architecture.
Drop the Flux UI addon and its Tailscale exposure because the UI lags the
current Flux APIs and reports misleading HelmRelease errors. Keep Flux managed
through the controllers themselves and use Rancher or the flux CLI for access.
The Tailscale cleanup role was deleting reserved service hostnames on later
deploy runs, which removed the live Rancher/Grafana/Prometheus/Flux proxy
nodes from the tailnet. Skip cleanup whenever the current cluster already has
those Tailscale services, while still allowing cleanup on fresh rebuilds.
The deploy pipeline never uses the flux binary after installation, so the
GitHub release download only adds a flaky failure point. Remove the step and
keep the bootstrap path kubectl-only.
Prometheus is exposed on port 9090 through the Tailscale LoadBalancer
service, so the configured external URL and repo docs should match the
actual address users reach after rebuilds.
Reserve grafana/prometheus/flux alongside rancher during rebuild cleanup so
stale tailnet devices do not force -1 hostnames. Tag the exposed Tailscale
services so operator-managed proxies are provisioned with explicit prod/service
tags from the tailnet policy.
The chart's post-install hook hardcodes rancher/kuberlr-kubectl which
can't download kubectl. Use Flux postRenderers to patch the job image
to bitnami/kubectl at render time.
The chart's post-install hook uses rancher/kuberlr-kubectl which fails
to download kubectl. The SA automountServiceAccountToken is managed
manually, so the hook is unnecessary.
Revert to idiomatic Grafana chart approach. ExternalSecret creates the
secret with admin-user/admin-password keys before Grafana's first start
on fresh cluster creation.
Prometheus needs operator.prometheus.io/name label selector. Flux UI pods
are labeled gitops-server not weave-gitops. Grafana now reads admin creds
from Doppler via ExternalSecret instead of hardcoded values.
Replace Ansible port-forwarding + tailscale serve with direct Tailscale LB
services matching the existing Rancher pattern. Each service gets its own
tailnet hostname (grafana/prometheus/flux.silverside-gopher.ts.net).
- Wait for Rancher and rancher-backup operator to be ready
- Patch default SA in cattle-resources-system (fixes post-install hook failure)
- Clean up failed patch-sa jobs
- Force reconcile rancher-backup HelmRelease
- Find latest backup from B2 using Backblaze API
- Create Restore CR to restore Rancher state from latest backup
- Wait for restore to complete before continuing
The S3 config caused the operator to try downloading kubectl, which fails in the container.
S3 credentials are correctly configured in the Backup CR and ExternalSecret instead.
Rancher now manages its own TLS (no longer tls:external), so it serves
HTTPS on port 443. The Tailscale LoadBalancer needs to expose both
HTTP (80) and HTTPS (443) targeting the corresponding container ports.
The Backup and Restore CRs need the rancher-backup CRDs to exist first.
Moved them to a separate kustomization that depends on the operator being ready.
With Tailscale LoadBalancer, TLS is not actually terminated at the edge.
The Tailscale proxy does TCP passthrough, so Rancher must serve its own
TLS certs. Setting tls: external caused Rancher to listen HTTP-only,
which broke HTTPS access through Tailscale.
Rancher 2.x uses embedded etcd, not an external PostgreSQL database.
The CATTLE_DB_CATTLE_* env vars are Rancher v1 only and were ignored.
- Remove all CNPG (CloudNativePG) cluster, operator, and related configs
- Remove external DB env vars from Rancher HelmRelease
- Remove rancher-db-password ExternalSecret
- Add rancher-backup operator HelmRelease (v106.0.2+up8.1.0)
- Add B2 credentials ExternalSecret for backup storage
- Add recurring Backup CR (daily at 03:00, 7 day retention)
- Add commented-out Restore CR for rebuild recovery
- Update Flux dependency graph accordingly
Adds tailscale-cleanup Ansible role that uses the Tailscale API to
delete offline devices matching reserved hostnames (e.g. rancher).
Runs during site.yml before Finalize to prevent hostname collisions
like rancher-1 on rebuild.
Requires TAILSCALE_API_KEY (API access token) passed as extra var.
- scripts/refresh-kubeconfig.sh fetches a fresh kubeconfig from CP1
- Ansible site.yml Finalize step now uses public IP instead of Tailscale
hostname for the kubeconfig server address
- Updated AGENTS.md with kubeconfig refresh instructions
- Skip WAL archive emptiness check so recovery works when restoring over
an existing backup archive in B2
- Add healthCheck for b2-credentials secret in CNPG kustomization to
prevent recovery from starting before ExternalSecret has synced
