DevOps & CI/CD Basics: Automating Your Software Pipeline
Bridge the gap between development and operations with this introduction to DevOps principles and Continuous Integration/Continuous Delivery (CI/CD). Learn how to automate your software delivery pipeline for faster, more reliable releases, and foster better collaboration within your team.
1. What is DevOps?
Understand the core philosophy of DevOps – a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle and provide continuous delivery with high software quality. Explore its key principles, culture, and benefits like increased speed, reliability, and collaboration.
Key Pillars of DevOps
- **Culture:** Collaboration, shared responsibility, feedback loops.
- **Automation:** Automating manual tasks in the pipeline.
- **Lean:** Minimizing waste, optimizing flow.
- **Measurement:** Monitoring performance and user experience.
2. Continuous Integration (CI)
Learn about Continuous Integration (CI), a development practice where developers frequently merge their code changes into a central repository. After each merge, automated builds and tests are run to detect integration errors early and fast, ensuring code quality and reducing integration headaches.
3. Continuous Delivery (CD) & Deployment
Beyond CI, discover Continuous Delivery (CD) and Continuous Deployment. CD ensures that software can be released to production at any time, while Continuous Deployment takes this a step further by automatically deploying every change that passes all stages of the production pipeline. Understand the differences and benefits of each.
4. Introduction to CI/CD Tools (e.g., GitHub Actions, Jenkins concepts)
Get an overview of popular CI/CD tools that automate your software pipeline. This section introduces concepts behind tools like GitHub Actions (integrated into GitHub workflows) and Jenkins (a widely used open-source automation server), illustrating their roles in automating builds, tests, and deployments.
Code Example: Basic GitHub Actions Workflow (Conceptual)
# .github/workflows/main.yml (Conceptual)
name: CI/CD Pipeline
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
build-and-test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up Node.js
uses: actions/setup-node@v2
with:
node-version: '18'
- name: Install dependencies
run: npm install
- name: Run tests
run: npm test
- name: Build project
run: npm run build
