Development Environment Setup with Docker Compose

This repository demonstrates how to replace multiple Docker commands with a Docker Compose configuration for a simpler development environment setup.

Before (Using Docker Commands)

Previously, we had to run multiple Docker commands separately:

---

Create Network

docker network create goals-net

---

Run MongoDB Container

docker run --name mongodb \
 -e MONGO_INITDB_ROOT_USERNAME=cagatay \
 -e MONGO_INITDB_ROOT_PASSWORD=secret \
 -v data:/data/db \
 --rm \
 -d \
 --network goals-net \
 mongo

---

Build Node API Image

docker build -t goals-node .

---

Run Node API Container

docker run --name goals-backend \
 -e MONGODB_USERNAME=<username> \
 -e MONGODB_PASSWORD=<password> \
 -v logs:/app/logs \
 -v /<projectLocalPath>/backend:/app \
 -v /app/node_modules \
 --rm \
 -d \
 --network goals-net \
 -p 80:80 \
 goals-node

---

Build React SPA Image

docker build -t goals-react .

---

Run React SPA Container

docker run --name goals-frontend \
 -v /<projectLocalPath>/frontend/src:/app/src \
 --rm \
 -d \
 -p 3000:3000 \
 -it \
 goals-react

---

Stop all Containers

docker stop mongodb goals-backend goals-frontend

After (Using Docker Compose)

Now, all these commands are replaced with a single docker-compose.yml file:

docker-compose up -d

Benefits of Using Docker Compose

• Simplified Commands: Instead of running multiple Docker commands, we now use single commands

  • Start all services: docker-compose up -d
  • Stop all services: docker-compose down
  • View logs: docker-compose logs

• Automatic Network Creation: Docker Compose automatically creates and manages networks

• Dependencies Management: Services can be configured to wait for other services using depends_on

• Environment Consistency: All team members use the same configuration

Prerequisites

• Docker
• Docker Compose
• Git

Getting Started

1. Clone the repository:

git clone [repository-url]
cd [repository-name]

2. Start the environment:

docker-compose up -d

Available Services

• Application (Node.js) - Port 80
• Mongodb - Port 27017
• React SPA - Port 3000
