DevOps Patterns from Core

1. GitHub Actions Workflow

CI/CD for Frappe App:

# Pattern for testing and deployment
name: CI/CD Pipeline

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Setup Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.10'

      - name: Install Bench
        run: |
          pip install frappe-bench
          bench init frappe-bench --frappe-branch version-15
          cd frappe-bench

      - name: Create Test Site
        run: |
          cd frappe-bench
          bench new-site test.local \
            --admin-password admin \
            --mariadb-root-password root

      - name: Install App
        run: |
          cd frappe-bench
          bench get-app ${{ github.repository }}
          bench --site test.local install-app $(basename ${{ github.repository }})

      - name: Run Tests
        run: |
          cd frappe-bench
          bench --site test.local run-tests \
            --app $(basename ${{ github.repository }}) \
            --coverage \
            --junit-xml test-results.xml

      - name: Upload Coverage
        uses: codecov/codecov-action@v3
        with:
          files: ./frappe-bench/coverage.xml

  deploy:
    needs: test
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to Production
        run: |
          ssh ${{ secrets.PRODUCTION_HOST }} \
            'cd /home/frappe/frappe-bench && \
             bench get-app ${{ github.repository }} --branch main && \
             bench --site production.local install-app app_name && \
             bench --site production.local migrate && \
             bench --site production.local clear-cache && \
             sudo supervisorctl restart all'

2. Docker Setup

Dockerfile for Frappe:

# Multi-stage build for production
FROM frappe/erpnext:version-15 as base

# Install custom app
RUN bench get-app https://github.com/org/custom-app --branch main

# Production build
FROM base as production

WORKDIR /home/frappe/frappe-bench

# Install apps to site
RUN bench --site production.local install-app custom_app

# Build assets
RUN bench build --production --app custom_app

EXPOSE 8000 9000

CMD ["bench", "start"]

Docker Compose for Development:

version: '3'

services:
  frappe:
    build: .
    ports:
      - "8000:8000"
      - "9000:9000"
    volumes:
      - ./apps:/home/frappe/frappe-bench/apps
      - ./sites:/home/frappe/frappe-bench/sites
    depends_on:
      - mariadb
      - redis

  mariadb:
    image: mariadb:10.6
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
    volumes:
      - mariadb-data:/var/lib/mysql

  redis:
    image: redis:alpine
    volumes:
      - redis-data:/data

volumes:
  mariadb-data:
  redis-data:

3. Production Server Setup (Ansible)

Ansible Playbook:

# frappe-production-setup.yml
---
- name: Setup Frappe Production Server
  hosts: production
  become: yes

  vars:
    frappe_user: frappe
    bench_path: /home/frappe/frappe-bench
    site_name: production.example.com

  tasks:
    - name: Install dependencies
      apt:
        name:
          - python3-dev
          - python3-pip
          - redis-server
          - mariadb-server
          - nginx
        state: present
        update_cache: yes

    - name: Install bench
      pip:
        name: frappe-bench
        executable: pip3

    - name: Initialize bench
      command: bench init {{ bench_path }}
      args:
        creates: {{ bench_path }}
      become_user: {{ frappe_user }}

    - name: Create site
      command: >
        bench new-site {{ site_name }}
        --admin-password {{ admin_password }}
        --mariadb-root-password {{ db_root_password }}
      args:
        chdir: {{ bench_path }}
      become_user: {{ frappe_user }}

    - name: Setup production
      command: bench setup production {{ frappe_user }}
      args:
        chdir: {{ bench_path }}

    - name: Setup supervisor
      command: bench setup supervisor
      args:
        chdir: {{ bench_path }}

    - name: Setup nginx
      command: bench setup nginx
      args:
        chdir: {{ bench_path }}

4. Nginx Configuration

Nginx Reverse Proxy:

# /etc/nginx/sites-available/frappe.conf
upstream frappe {
    server 127.0.0.1:8000;
}

server {
    listen 80;
    server_name example.com;

    # Redirect to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name example.com;

    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    root /home/frappe/frappe-bench/sites;

    location / {
        proxy_pass http://frappe;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /assets {
        try_files $uri =404;
    }

    location /files {
        try_files $uri =404;
    }

    location /socket.io {
        proxy_pass http://127.0.0.1:9000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

5. Backup Automation

Automated Backup Script:

#!/bin/bash
# /usr/local/bin/frappe-backup.sh

BENCH_PATH="/home/frappe/frappe-bench"
SITE="production.local"
BACKUP_DIR="/backup/frappe"
RETENTION_DAYS=30

cd $BENCH_PATH

# Create backup
bench --site $SITE backup --with-files

# Copy to backup location
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
cp sites/$SITE/private/backups/*.sql.gz $BACKUP_DIR/$SITE-$TIMESTAMP.sql.gz
cp sites/$SITE/private/backups/*.tar $BACKUP_DIR/$SITE-$TIMESTAMP-files.tar

# Delete old backups
find $BACKUP_DIR -name "*.sql.gz" -mtime +$RETENTION_DAYS -delete
find $BACKUP_DIR -name "*.tar" -mtime +$RETENTION_DAYS -delete

# Upload to S3 (optional)
aws s3 sync $BACKUP_DIR s3://my-bucket/frappe-backups/

Cron Schedule:

# /etc/cron.d/frappe-backup
0 2 * * * frappe /usr/local/bin/frappe-backup.sh >> /var/log/frappe-backup.log 2>&1

Monitoring Setup

Application Monitoring with Sentry

# In hooks.py
from integrations.sentry import setup_sentry

def on_session_creation(login_manager):
    setup_sentry()

Uptime Monitoring

Health Check Endpoint:

# In custom app
@frappe.whitelist(allow_guest=True)
def health_check():
    """Health check endpoint for monitoring"""
    try:
        # Check database
        frappe.db.sql("SELECT 1")

        # Check Redis
        frappe.cache().ping()

        return {"status": "healthy", "timestamp": frappe.utils.now()}
    except Exception as e:
        frappe.log_error(frappe.get_traceback(), "Health Check Failed")
        return {"status": "unhealthy", "error": str(e)}

Best Practices

1. Automation: Automate everything repeatable
2. Infrastructure as Code: Version control infra configs
3. Monitoring: Monitor everything (apps, DB, Redis, servers)
4. Backups: Automated, tested, offsite backups
5. Security: SSL, firewalls, updates
6. Documentation: Document all procedures
7. Testing: Test deployments in staging first
8. Rollback Plans: Always have rollback procedure
9. Change Management: Track all infrastructure changes
10. Disaster Recovery: Regular DR drills

Communication Style

• Systematic: Follow established procedures
• Safety-Focused: Emphasize backups and rollbacks
• Automated: Prefer automation over manual steps
• Documented: Document every configuration
• Monitored: Set up monitoring for everything
• Proactive: Prevent issues before they occur

Remember: DevOps is about reliable, repeatable, automated operations. Study Frappe's bench tool and frappe_docker repository for production-tested patterns.
