# Setup CI/CD Pipeline

Automated continuous integration and deployment pipelines for Urbit ship management, application development, and infrastructure-as-code workflows.

## Overview

CI/CD for Urbit enables:
- Automated ship deployments
- Infrastructure-as-code (Terraform/Ansible)
- Urbit app testing and deployment
- Automated backup validation
- Configuration drift detection

## Pipeline Types

### 1. Infrastructure Deployment Pipeline
### 2. Urbit App Development Pipeline
### 3. Ship Maintenance Pipeline

---

## Pipeline 1: Infrastructure Deployment (GitHub Actions)

Automates VPS provisioning and ship deployment using Terraform.

## Pipeline 3: Ship Maintenance (Automated Backups)

Scheduled maintenance tasks via GitHub Actions.

**.github/workflows/backup-ship.yml**:
```yaml
name: Ship Backup and Maintenance
user-invocable: true
disable-model-invocation: false

on:
  schedule:
    - cron: '0 3 * * 0'  # Weekly Sunday 3 AM
  workflow_dispatch:

jobs:
  backup:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Configure SSH
        run: |
          mkdir -p ~/.ssh
          echo "${{ secrets.SSH_PRIVATE_KEY }}" > ~/.ssh/id_rsa
          chmod 600 ~/.ssh/id_rsa
          ssh-keyscan ${{ secrets.SHIP_IP }} >> ~/.ssh/known_hosts

      - name: Run backup script
        run: |
          ssh urbit@${{ secrets.SHIP_IP }} "/usr/local/bin/urbit-backup.sh"

      - name: Verify backup
        run: |
          ssh urbit@${{ secrets.SHIP_IP }} "ls -lh /backups/urbit/ | tail -1"

      - name: Upload to S3
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        run: |
          BACKUP_FILE=$(ssh urbit@${{ secrets.SHIP_IP }} "ls -t /backups/urbit/*.tar.gz | head -1")
          ssh urbit@${{ secrets.SHIP_IP }} "aws s3 cp $BACKUP_FILE s3://urbit-backups/"

      - name: Run |pack maintenance
        run: |
          ssh urbit@${{ secrets.SHIP_IP }} "docker exec ship /bin/sh -c \"echo '|pack' | urbit-worker dojo\""

      - name: Report pier size
        run: |
          SIZE=$(ssh urbit@${{ secrets.SHIP_IP }} "du -sh /home/urbit/sampel-palnet | cut -f1")
          echo "Current pier size: $SIZE"
```

---

## Secrets Management

**Required secrets** (GitHub/GitLab):
- `DIGITALOCEAN_TOKEN` / `LINODE_TOKEN` / `AWS_ACCESS_KEY_ID`
- `SSH_PRIVATE_KEY`: SSH key for server access
- `SHIP_KEYFILE`: Planet keyfile (base64 encoded)
- `SHIP_IP`: Production ship IP address
- `AWS_SECRET_ACCESS_KEY`: For S3 backup uploads

**Setting secrets**:
```bash
# GitHub
gh secret set DIGITALOCEAN_TOKEN --body "dop_v1_..."

# GitLab
# Settings → CI/CD → Variables → Add Variable
```

---

## Best Practices

1. **Secrets**: Never commit keyfiles, use GitHub/GitLab secrets
2. **Testing**: Always test on fake ships before production deployment
3. **Idempotency**: Terraform/Ansible ensure reproducible deployments
4. **Validation**: Verify ship boots before marking deployment successful
5. **Rollback**: Keep previous infrastructure state for rollback
6. **Monitoring**: Integrate deployment notifications (Slack, email)
7. **Documentation**: Auto-generate deployment docs in pipeline
8. **Cost tracking**: Tag cloud resources for billing analysis

---

## Troubleshooting

**Pipeline fails at Terraform apply**:
- Check provider API credentials
- Verify quota limits not exceeded
- Review Terraform state for conflicts

**SSH connection timeout**:
- Verify firewall allows port 22
- Check SSH key configured correctly
- Wait longer for instance boot

**Ship won't boot**:
- Check keyfile validity (not expired, not already used)
- Verify sufficient memory (4GB+ RAM)
- Review systemd logs: `journalctl -u urbit-ship -n 50`

**Backup fails**:
- Ensure ship stopped before backup (never backup live pier)
- Check disk space: `df -h`
- Verify S3 credentials

## Summary

CI/CD pipelines for Urbit enable automated infrastructure deployment (Terraform + Ansible), app development workflows (testing on fake ships, GitLab CI), and maintenance automation (scheduled backups, |pack). GitHub Actions and GitLab CI provide robust platforms for infrastructure-as-code, secret management, and deployment validation. Pipelines ensure reproducible deployments, automated testing, and comprehensive backup strategies.
