Erich Blume 61ca1ca305 Deploy Tailscale operator on ringtail k3s cluster (#215 ) ## Summary - Extract shared Tailscale operator resources (CRDs, RBAC, Deployment, ProxyClass, DNSConfig) into `tailscale-operator-base/` so both clusters reference the same manifests - Add `tailscale-operator-ringtail/` overlay with 1-replica ProxyGroup and ExternalSecret for the shared OAuth client - Add ArgoCD Application targeting `ringtail.tail8d86e.ts.net:6443` - Update `.yamllint.yaml` ignore path for the moved `operator.yaml` ## Deployment and Testing - [ ] Sync `apps` app to pick up the new Application definition - [ ] `argocd app sync tailscale-operator-ringtail` - [ ] Verify ExternalSecret syncs: `kubectl --context=k3s-ringtail -n tailscale get externalsecret` - [ ] Verify operator pod runs: `kubectl --context=k3s-ringtail -n tailscale get pods` - [ ] Verify ProxyGroup ready: `kubectl --context=k3s-ringtail -n tailscale get proxygroups` - [ ] Verify indri operator still works: `argocd app diff tailscale-operator` - [ ] Check Tailscale admin for new operator device with `tag:k8s-operator` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/215		2026-02-19 09:33:05 -08:00

Tailscale Kubernetes Operator

Manifests for the Tailscale Kubernetes Operator, managed via ArgoCD.

Source

operator.yaml - Static manifest from https://github.com/tailscale/tailscale/tree/main/cmd/k8s-operator/deploy/manifests
Secret block removed from operator.yaml - managed separately via secret.yaml.tpl
Image reference changed to fully-qualified docker.io/tailscale/k8s-operator:stable

Prerequisites

OAuth client in Tailscale admin console with:
- Devices: Core (Read & Write) - tag: tag:k8s-operator
- Auth Keys: Read & Write
- Services: Write
ACL with tag:k8s-operator owning tag:k8s (so operator can tag resources it creates)

Manual Bootstrap (Before ArgoCD)

Tailscale operator must be deployed before ArgoCD since ArgoCD uses Tailscale for ingress.

# 1. Create namespace
kubectl create namespace tailscale

# 2. Apply OAuth secret (uses 1Password)
op inject -i argocd/manifests/tailscale-operator/secret.yaml.tpl | kubectl apply -f -

# 3. Apply manifests via kustomize
kubectl apply -k argocd/manifests/tailscale-operator/

Ongoing Management (After ArgoCD)

Once ArgoCD is running, the operator is managed by the tailscale-operator ArgoCD Application. ArgoCD pulls manifests from forge and applies them automatically.

ArgoCD CLI Commands

# Check application status
argocd app get tailscale-operator

# Trigger a sync (pull latest from forge and apply)
argocd app sync tailscale-operator

# Preview what would change without applying
argocd app diff tailscale-operator

# View deployment history
argocd app history tailscale-operator

# Hard refresh (clear cache and re-fetch from git)
argocd app get tailscale-operator --hard-refresh

Verification

# Check operator pod is running
kubectl get pods -n tailscale

# Check operator logs
kubectl logs -n tailscale -l app.kubernetes.io/name=operator

Notes

TODO: The OAuth secret (operator-oauth) is not managed by ArgoCD and must be applied manually. Future improvement: integrate with a secrets operator (e.g., External Secrets).
Services using the Tailscale LoadBalancer should reference the ProxyClass:
```
annotations:
  tailscale.com/proxy-class: "default"
```
The egress proxy for forge is deprecated. Forge is now accessible via Caddy at forge.ops.eblu.me (HTTPS) and forge.ops.eblu.me:2222 (SSH), which pods can reach directly.
