🍻Makefile and Docker-Compose

A place for simple, repeatable CI/CD patterns, examples and code-snippets for a solid Developer experience. Here you'll find examples of using Makefiles for CI/CD.

Make for task running and dependency management:

• Manages reusable, consistent task running for CI/CD with minimal dependency

• Can run prerequisite tasks / commands for dependency chaining

• Allows flexibility to run tasks that don't require containerization (eg: for a linux only environment, running a curl task natively doesn't require a docker container)

• Native to Unix based Operating Systems and WSL2. 3mb executable on Windows

• Small learning curve with widely available standards and patterns

• A mature and industry-wide used tool with a large online community

• Entirely Opensource

Example:

# Variables
s3_bucket = "my-frontend-website"

# Install npm dependencies and start container on port "http://localhost:3001"
start:
	docker-compose up -d --build node
	echo "Navigate to http://localhost:3001"

# Build application for deployment
build:
	docker-compose run --rm --entrypoint "npm run build" node

# First run the dependent "build" task then deploy build folder to AWS S3 using awscli
deploy: build
	aws s3 sync build/ s3://$(s3_bucket) --acl public-read"
	echo "Upload complete."

Docker-Compose for container management:

• A mature and Industry wide used tool with a large online community

• YAML based configuration with small learning curve

• Decoupled from task running and dependency management

• On it's own docker-compose has limitations which are mitigated by make which takes care of container based task running and task dependencies

Example:

version: '3.7'

services:
  node:
    container_name: node
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - '.:/app'
      - '/app/node_modules'
    ports:
      - 3001:3000
    environment:
      - CHOKIDAR_USEPOLLING=true
