# GitHub Actions Setup Complete! 🎉

Your repository is now configured with GitHub Actions for automated building and deployment.

## What's Been Added

### GitHub Actions Workflows

#### 1. `.github/workflows/build-and-push.yml`
**Purpose:** Build Docker image and push to your Gitea registry

**Triggers:**
- ✅ When you push a version tag (e.g., `v1.0.0`, `v2.1.0`)
- ✅ Manual trigger from GitHub Actions tab

**What it does:**
1. Checks out your code
2. Builds Docker image
3. Logs into your Gitea registry
4. Pushes image with version tag + `latest` tag
5. Shows deploy command in output

#### 2. `.github/workflows/ci.yml`
**Purpose:** Run tests and quality checks

**Triggers:**
- ✅ On push to `main` or `develop` branches
- ✅ On pull requests

**What it does:**
1. **Lint:** Runs RuboCop (code style)
2. **Security:** Runs Brakeman (security scan)
3. **Test:** Runs your test suite with PostgreSQL
4. **Build Test:** Verifies Dockerfile builds successfully

### Documentation

- ✅ `.github/SECRETS_SETUP.md` - How to configure GitHub Secrets
- ✅ `.github/WHAT_TO_COMMIT.md` - What's safe to commit publicly
- ✅ `GITHUB_ACTIONS_SETUP.md` - This file!

### Updated Files

- ✅ `README.md` - Added CI/CD section
- ✅ `k8s/deployment.yaml` - Placeholder image paths
- ✅ `k8s/migrate-job.yaml` - Placeholder image paths
- ✅ `.gitignore` - Already excludes secrets ✅

## Your Next Steps

### Step 1: Add GitHub Secrets

Go to your GitHub repository → **Settings** → **Secrets and variables** → **Actions**

Add these 4 secrets:

| Secret Name | Value | Example |
|-------------|-------|---------|
| `GITEA_REGISTRY` | Your Gitea URL (no https://) | `gitea.example.com` |
| `GITEA_USERNAME` | Your Gitea username | `johndoe` |
| `GITEA_TOKEN` | Gitea access token | `gtea_abc123...` |
| `GITEA_REPO` | Repo path | `johndoe/turbovault` |

**Detailed instructions:** [.github/SECRETS_SETUP.md](../.github/SECRETS_SETUP.md)

### Step 2: Get Gitea Access Token

1. Login to your Gitea instance
2. **Settings** → **Applications** → **Manage Access Tokens**
3. Click **Generate New Token**
4. Name: `github-actions`
5. Permissions:
   - ✅ `package:read`
   - ✅ `package:write`
6. Click **Generate Token**
7. Copy the token (starts with `gtea_`)
8. Add to GitHub as `GITEA_TOKEN` secret

### Step 3: Push to GitHub

```bash
# Make sure you're in the project directory
cd turbovault-web

# Run the setup script
./scripts/setup-github.sh

# Or manually:
git add .
git commit -m "Add GitHub Actions for CI/CD"
git push origin main
```

### Step 4: Test the Workflow

**Option A: Manually trigger a build**

1. Go to your GitHub repository
2. Click **Actions** tab
3. Click **Build and Push to Gitea**
4. Click **Run workflow** button
5. Enter tag: `test` or `v0.1.0`
6. Click **Run workflow**
7. Watch it build!

**Option B: Create a version tag**

```bash
# Create and push a tag
git tag v1.0.0
git push origin v1.0.0

# This will automatically trigger the build workflow
```

### Step 5: Verify Image in Gitea

1. Login to your Gitea instance
2. Go to your repository
3. Click **Packages** tab
4. You should see `turbovault` package with your tag

### Step 6: Deploy to Kubernetes

```bash
# Update deployment with new image
kubectl set image deployment/turbovault \
  turbovault=gitea.example.com/username/turbovault:v1.0.0 \
  -n turbovault

# Or use the deployment script
./scripts/deploy-k8s.sh
```

## Common Tasks

### Release a New Version

```bash
# 1. Make changes and commit
git add .
git commit -m "Add new feature"
git push origin main

# 2. Wait for CI to pass (check Actions tab)

# 3. Create release tag
git tag v1.1.0
git push origin v1.1.0

# 4. GitHub Actions builds and pushes to Gitea automatically

# 5. Deploy to k8s
kubectl set image deployment/turbovault \
  turbovault=gitea.example.com/username/turbovault:v1.1.0 \
  -n turbovault
```

### Rollback to Previous Version

```bash
# Deploy previous tag
kubectl set image deployment/turbovault \
  turbovault=gitea.example.com/username/turbovault:v1.0.0 \
  -n turbovault

# Watch rollout
kubectl rollout status deployment/turbovault -n turbovault
```

### View Build Logs

1. Go to GitHub repository
2. Click **Actions** tab
3. Click on a workflow run
4. Click on job name to see logs

### Rebuild Latest

```bash
# Delete and recreate tag (forces rebuild)
git tag -d latest
git push origin :refs/tags/latest
git tag latest
git push origin latest
```

## Troubleshooting

### Build fails with "unauthorized"

**Problem:** Can't login to Gitea registry

**Solution:**
1. Verify `GITEA_TOKEN` in GitHub secrets is correct
2. Check token has `package:write` permission
3. Test locally: `docker login gitea.example.com`

### Image pushes but k8s can't pull

**Problem:** ImagePullBackOff in Kubernetes

**Solution:**
1. Verify k8s secret exists: `kubectl get secret gitea-registry -n turbovault`
2. Check `imagePullSecrets` in deployment.yaml
3. See [k8s/GITEA_SETUP.md](../k8s/GITEA_SETUP.md)

### CI tests fail

**Problem:** Tests don't pass in GitHub Actions

**Solution:**
1. Run tests locally: `rails test`
2. Check PostgreSQL connection
3. Review test logs in Actions tab
4. Tests are set to `continue-on-error: true` for now (won't block builds)

### Workflow doesn't trigger

**Problem:** Pushing tag doesn't start build

**Solution:**
1. Check tag format: must be `v*.*.*` (e.g., `v1.0.0`)
2. Verify workflow file exists: `.github/workflows/build-and-push.yml`
3. Check Actions tab for errors

## Benefits

### ✅ What You Get

1. **Automated Builds** - No manual Docker commands
2. **Version Control** - Each tag creates a versioned image
3. **CI/CD Pipeline** - Auto-test every change
4. **Quality Checks** - Linting and security scans
5. **Rollback Safety** - Keep all versions in Gitea
6. **Collaboration** - Contributors get CI feedback on PRs

### 🎯 Workflow Benefits

- **For You:** Push tag → image automatically builds → deploy
- **For Contributors:** Submit PR → auto-tested → you review
- **For Production:** Tagged releases → immutable versions → safe rollbacks

## Next Steps

1. ✅ Add GitHub Secrets ([.github/SECRETS_SETUP.md](../.github/SECRETS_SETUP.md))
2. ✅ Push code to GitHub
3. ✅ Test workflow (manual trigger or push tag)
4. ✅ Verify image in Gitea
5. ✅ Deploy to Kubernetes
6. ✅ Celebrate! 🎉

## Questions?

- **"Do I need to push to Gitea too?"** → No! GitHub Actions does it for you
- **"What about the source code?"** → Push to GitHub, images go to Gitea automatically
- **"Can I still build locally?"** → Yes! Docker build commands still work
- **"Do contributors need Gitea access?"** → No! Only you need it (for GitHub Secrets)
- **"How do I disable a workflow?"** → GitHub → Actions → Select workflow → Disable

---

**You're all set!** Add your GitHub Secrets and push a tag to see it in action! 🚀
