Basic CI/CD Pipeline Example

This document provides examples of CI/CD pipeline configurations for automating testing, building, and deploying applications.

.gitlab-ci.yml

stages:
  - build
  - test
  - deploy
 
build-job:
  stage: build
  script:
    - echo "Compiling the code... 🛠️"
    - echo "Compile complete. ✅"
 
unit-test-job:
  stage: test
  script:
    - echo "Running unit tests... This will take about 60 seconds. 🧪"
    - sleep 60
    - echo "Code coverage is 90% 📊"
 
lint-test-job:
  stage: test
  script:
    - echo "Linting code... This will take about 10 seconds. 🔍"
    - sleep 10
    - echo "No lint issues found. 🧹"
 
deploy-job:
  stage: deploy
  script:
    - echo "Deploying application... 🚀"
    - echo "Application successfully deployed. 🎉"
    - echo "Completed... ✅"

Explanation

1. Variables:

   • IMAGE_NAME and IMAGE_TAG are defined to specify the Docker image name and tag.

2. Stages:

   • test: Runs tests to ensure the code is working correctly.
   • build: Builds the Docker image.
   • deploy: Deploys the application to a server.

3. Jobs:

   • run_tests: Uses Python image, installs make, and runs tests.
   • build_image: Uses Docker-in-Docker to build and push Docker images.
   • deploy: Uses SSH to connect to the server, remove old containers, and run the new Docker container.

Additional Examples

• Build Job: Compiles the code.
• Unit Test Job: Runs unit tests and checks code coverage.
• Lint Test Job: Checks the code for linting issues.
• Deploy Job: Deploys the application if all tests pass.

Icons and Emojis

• 🛠️: Build
• ✅: Success
• 🧪: Testing
• 📊: Coverage
• 🔍: Linting
• 🧹: Cleaning
• 🚀: Deployment
• 🎉: Celebration

By using these configurations, you can set up a robust CI/CD pipeline that automates the process of testing, building, and deploying your applications.
