## Creating GCP Service Account Key
58+
59+
### Step 1: Create Service Account
60+
```bash
61+
gcloud iam service-accounts create github-actions \
62+
--display-name="GitHub Actions" \
63+
--description="Service account for GitHub Actions deployment"
64+
```
65+
66+
### Step 2: Grant Required Permissions
67+
```bash
68+
gcloud projects add-iam-policy-binding serverless-462906 \
69+
--member="serviceAccount:[email protected]" \
70+
--role="roles/cloudfunctions.developer"
71+
72+
gcloud projects add-iam-policy-binding serverless-462906 \
73+
--member="serviceAccount:[email protected]" \
74+
--role="roles/datastore.user"
75+
76+
gcloud projects add-iam-policy-binding serverless-462906 \
77+
--member="serviceAccount:[email protected]" \
78+
--role="roles/storage.admin"
79+
```
80+
81+
### Step 3: Create and Download Key
82+
```bash
83+
gcloud iam service-accounts keys create github-actions-key.json \
84+
--iam-account=github-actions@serverless-462906.iam.gserviceaccount.com
85+
```
86+
87+
### Step 4: Add Key to GitHub Secrets
88+
1. Open the `github-actions-key.json` file
89+
2. Copy the entire JSON content
90+
3. Add it as the `GCP_SA_KEY` secret in GitHub
91+
4. **Delete the local file** for security: `del github-actions-key.json`
92+
93+
## Deployment Workflow
94+
95+
### Automatic Deployments
96+
- **Staging:** Push to `develop` branch → deploys to `contact-form-api-staging`
97+
- **Production:** Push to `main` branch → deploys to `contact-form-api`
98+
99+
### Manual Trigger
100+
You can also trigger deployments manually from the GitHub Actions tab.
101+
102+
## Workflow Features
103+
104+
✅ **Testing:** Runs on Node.js 18.x and 20.x
105+
✅ **Linting:** Code quality checks
106+
✅ **Security:** Dependency audits
107+
✅ **Coverage:** Code coverage reports
108+
✅ **Staging:** Deploy to staging environment
109+
✅ **Production:** Deploy to production with release creation
110+
111+
## Next Steps
112+
113+
1. **Create GitHub repository** (if not already done)
114+
2. **Add all secrets** listed above
115+
3. **Create service account** and add key
116+
4. **Push code to GitHub**
117+
5. **Create `develop` branch** for staging deployments
118+
6. **Push to `main`** for production deployment
119+
120+
## Monitoring Deployments
121+
122+
- Check the **Actions** tab in GitHub to see deployment status
123+
- View logs for any deployment issues
124+
- Monitor your GCP Cloud Functions console for function health
125+
126+
## Troubleshooting
127+
128+
### Common Issues:
129+
- **Permission denied:** Check service account permissions
130+
- **Invalid secrets:** Verify all secrets are correctly formatted
131+
- **Deployment timeout:** Check function memory/timeout settings
132+
- **CORS errors:** Verify CORS_ORIGIN settings match your website
133+
134+
### Getting Help:
135+
- Check GitHub Actions logs for detailed error messages
136+
- Use `gcloud functions logs read contact-form-api` for runtime logs
137+
- Verify secrets are properly set in GitHub repository settings
