fastpass GitOps Bootstrap
This document is the complete procedure to go from a freshly provisioned Talos
cluster to a fully GitOps-managed platform. After completing these steps, all
future changes are made via git — never kubectl apply again.
Prerequisites
- Talos cluster running (
space-mountain,big-thunder-mountain,splash-mountainCP nodes) - Cilium installed as CNI (done at Talos bootstrap via talhelper)
kubectlconfigured and pointing atfastpasskubeconfigoncity-hallat~/.kube/config- 1Password Connect credentials JSON downloaded from your 1Password account (Developer Tools > Connect Servers > New Server)
- 1Password Connect token generated for the
mk-labsvault
Step 1 — Install ArgoCD
This is the only kubectl apply you will ever run against this cluster.
kubectl create namespace argocd
kubectl apply -n argocd \
--server-side \
--force-conflicts \
-f https://raw.githubusercontent.com/argoproj/argo-cd/v3.4.2/manifests/install.yaml
# Wait for ArgoCD to be healthy
kubectl wait --for=condition=available deployment/argocd-server \
-n argocd --timeout=120s
Step 2 — Bootstrap the 1Password Connect secret
This is the only secret you will ever manage manually. Everything else flows through ESO from here.
# Create the namespace first
kubectl create namespace onepassword-connect
# Apply the credentials file (downloaded from 1Password)
kubectl create secret generic op-credentials \
--from-file=1password-credentials.json=/path/to/1password-credentials.json \
-n onepassword-connect
# Apply the Connect API token
kubectl create secret generic connect-token \
--from-literal=token=<your-connect-token> \
-n onepassword-connect
Step 3 — Apply the App of Apps
This is the second and final manual apply. From this point on, ArgoCD manages everything, including itself.
kubectl apply -n argocd -f cluster/argocd/apps-of-apps.yaml
Step 4 — Watch it go
# Watch all Applications come up in wave order
kubectl get applications -n argocd -w
# Or use the ArgoCD UI
kubectl port-forward svc/argocd-server -n argocd 8080:443
# Then open https://localhost:8080
# Default admin password:
kubectl -n argocd get secret argocd-initial-admin-secret \
-o jsonpath="{.data.password}" | base64 -d
Step 2.5 — Vendor Gateway API CRDs
Before applying the App of Apps, vendor the Gateway API CRDs into git. Run from the repo root on city-hall:
curl -L https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.1/standard-install.yaml \
-o cluster/platform/gateway-api/manifests/standard-install.yaml
curl -L https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.1/experimental-install.yaml \
-o cluster/platform/gateway-api/manifests/experimental-install.yaml
git add cluster/platform/gateway-api/manifests/
git commit -m "feat(platform): vendor gateway-api CRDs v1.2.1"
git push
Wave Order
| Wave | Application | Depends On |
|---|---|---|
| 1 | external-secrets | (none) |
| 2 | onepassword-connect | external-secrets |
| 3 | cert-manager | onepassword-connect (CF secret) |
| 3 | gateway-api-crds | (none — CRDs only) |
| 4 | cilium-config | gateway-api-crds (CRDs exist) |
| 5 | ingress-nginx | cilium-config (LB pool) |
| 5 | gateway (resource) | cilium-config (GatewayClass) |
| 6 | external-dns | ingress-nginx (IP to register) |
| 10+ | applications/* | platform complete |
Upgrading ArgoCD
kubectl apply -n argocd \
--server-side \
--force-conflicts \
-f https://raw.githubusercontent.com/argoproj/argo-cd/v<NEW_VERSION>/manifests/install.yaml
Update the version comment in cluster/argocd/install.yaml to match.
Troubleshooting
# Check sync status of all apps
kubectl get applications -n argocd
# Check why an app is out of sync
kubectl describe application <name> -n argocd
# Force a sync
kubectl patch application <name> -n argocd \
--type merge \
-p '{"operation": {"initiatedBy": {"username": "admin"}, "sync": {}}}'
# Check ESO secret sync
kubectl get externalsecret -A
kubectl describe externalsecret <name> -n <namespace>
