## Setup Instructions

### Prerequisites

1. Gitea must be configured and accessible
2. Flux must be installed in the K3s cluster
3. Git repository must be created in Gitea

### Steps

1. **Create Git Repository in Gitea:**
   - Access Gitea: http://192.168.1.121:3000
   - Create new repository: `gitops`
   - Initialize with README

2. **Push GitOps Manifests:**
   ```bash
   git clone http://192.168.1.121:3000/hc-stack/gitops.git
   cd gitops
   # Copy manifests from this directory
   git add .
   git commit -m "Initial GitOps configuration"
   git push
   ```

3. **Configure Flux GitRepository:**
   ```bash
   ssh ubuntu@192.168.1.188
   export KUBECONFIG=/etc/rancher/k3s/k3s.yaml
   
   # Create GitRepository
   sudo kubectl apply -f - <<EOF
   apiVersion: source.toolkit.fluxcd.io/v1beta2
   kind: GitRepository
   metadata:
     name: gitops-repo
     namespace: flux-system
   spec:
     interval: 1m
     url: http://192.168.1.121:3000/hc-stack/gitops.git
     ref:
       branch: main
   EOF
   ```

4. **Create Kustomizations:**
   ```bash
   # Infrastructure Kustomization
   sudo kubectl apply -f - <<EOF
   apiVersion: kustomize.toolkit.fluxcd.io/v1
   kind: Kustomization
   metadata:
     name: infrastructure
     namespace: flux-system
   spec:
     interval: 5m
     path: ./infrastructure
     prune: true
     sourceRef:
       kind: GitRepository
       name: gitops-repo
   EOF
   
   # Applications Kustomization
   sudo kubectl apply -f - <<EOF
   apiVersion: kustomize.toolkit.fluxcd.io/v1
   kind: Kustomization
   metadata:
     name: applications
     namespace: flux-system
   spec:
     interval: 5m
     path: ./apps
     prune: true
     sourceRef:
       kind: GitRepository
       name: gitops-repo
   EOF
   ```

5. **Monitor Reconciliation:**
   ```bash
   sudo kubectl get gitrepository -n flux-system
   sudo kubectl get kustomization -n flux-system
   sudo kubectl logs -n flux-system -l app=kustomize-controller -f
   ```

## Notes

- If Gitea requires authentication, create a secret:
  ```bash
  sudo kubectl create secret generic gitops-repo-auth \
    --from-literal=username=<username> \
    --from-literal=password=<token> \
    -n flux-system
  ```
  
  Then update GitRepository to reference the secret:
  ```yaml
  spec:
    secretRef:
      name: gitops-repo-auth
  ```
