## Required Configuration

Before deploying, you must:

1. **Create Renovate Bot User in Gitea**:
   - Username: `renovate-bot`
   - Email: `renovate-bot@bsdserver.nl`
   - Full name: "Renovate Bot"

2. **Generate Personal Access Token** with scopes:
   - `repo` (Read and Write)
   - `user` (Read)
   - `issue` (Read and Write)
   - `organization` (Read)

3. **Update terraform.tfvars**:
   ```hcl
   renovate_endpoint   = "https://gitea.bsdserver.nl/api/v1/"
   renovate_token      = "your-actual-token-here"
   renovate_git_author = "Renovate Bot <renovate-bot@bsdserver.nl>"
   renovate_username   = "renovate-bot"
   ```

4. **Initialize Terraform**:
   ```bash
   terraform init
   terraform plan
   terraform apply
   ```

## Next Steps

1. **Deploy the Module**:
   ```bash
   cd /path/to/terraform-docker-renovate
   terraform init
   terraform plan
   terraform apply
   ```

2. **Verify Deployment**:
   ```bash
   docker ps | grep renovate
   docker logs renovate -f
   ```

3. **Configure Repositories**:
   - Add `renovate.json` to each repository
   - Use `files/example-renovate.json` as a template
   - Enable autodiscovery or add bot as collaborator

4. **Set Up Scheduling**:
   - Configure cron job
   - Or use Gitea Actions workflow
   - See `files/example-gitea-workflow.yaml`

5. **Monitor and Test**:
   - Wait for Renovate to create onboarding PRs
   - Review and merge onboarding PRs
   - Monitor dependency update PRs
