CI/CD Documentation
Introduction
CI/CD (Continuous Integration/Continuous Deployment) is a method to automate the software development process. It allows teams to deploy code changes automatically, ensuring a streamlined workflow and quicker feedback.
Key Concepts
Important: Understanding these concepts is crucial for effective CI/CD implementation.
- Continuous Integration (CI): The practice of automatically testing and merging code into a shared repository.
- Continuous Delivery (CD): The ability to deploy code to production at any time with the push of a button.
- Continuous Deployment: Automatically deploying every change that passes automated tests.
# Example of a simple CI/CD pipeline configuration in YAML
version: '3'
services:
app:
build: .
ports:
- "5000:5000"
environment:
- NODE_ENV=production
Benefits of CI/CD
- Faster time to market
- Improved quality
- Reduced integration issues
- Increased team collaboration
Best Practices
Implementing CI/CD effectively requires adhering to certain best practices:
- Automate testing and deployment processes.
- Ensure a clean and maintainable codebase.
- Use feature flags for gradual rollouts.
- Monitor and log deployments for performance insights.
