# Argo Rollouts Deployment for f3s Cluster
Argo Rollouts is a Kubernetes controller for progressive delivery strategies including canary, blue-green, and A/B testing deployments.
## Overview
- **Namespace**: `cicd` (alongside ArgoCD)
- **Deployment Mode**: Single instance
- **CRD**: Rollout custom resource for progressive deployments
- **Integration**: Works with ArgoCD for GitOps-based rollouts
## Installation
```bash
just install
```
## Verification
```bash
just status
```
Check that the rollouts controller pod is running:
```bash
kubectl get pods -n cicd -l app.kubernetes.io/name=argo-rollouts
```
Check CRD is installed:
```bash
kubectl get crd | grep rollout
```
## Demo: Tracing-Demo Frontend Rollout
The frontend service uses a Canary strategy:
1. Deploy new version
2. Send 50% traffic to new version
3. Monitor for 2 minutes
4. If successful, shift 100% traffic
5. If failures detected, rollback
### Watch Rollout Progress
```bash
# Real-time status
kubectl argo rollouts get rollouts tracing-demo-frontend -n services --watch
# Full rollout status
kubectl argo rollouts status tracing-demo-frontend -n services
# Describe rollout details
kubectl describe rollout tracing-demo-frontend -n services
```
### Trigger a New Rollout
Update the frontend image tag in git (or use kubectl):
```bash
# Patch to trigger new rollout
kubectl patch rollout tracing-demo-frontend -n services \
--type json -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/image", "value":"registry.lan.buetow.org:30001/tracing-demo-frontend:v2"}]'
```
Or via git commit and ArgoCD sync.
### Manual Promotion (Skip Canary Steps)
```bash
kubectl argo rollouts promote tracing-demo-frontend -n services
```
### Abort/Rollback
```bash
kubectl argo rollouts abort tracing-demo-frontend -n services
```
