Setting Up Docker for Microservices

Before developing microservices, it's crucial to set up Docker properly and understand basic commands. This ensures a smooth experience managing multiple services in isolated containers.

Installing Docker

If Docker isn't already installed on your system:

Visit https://docs.docker.com/get-docker/
Follow installation instructions for your OS (Windows, macOS, Linux)
Verify the installation:
```
docker --version
```

Basic Docker Commands

List containers:
```
docker ps -a
```
Build image:
```
docker build -t myservice .
```
Run container:
```
docker run -d -p 3000:3000 myservice
```

Running Multiple Services in Containers

Let’s run two services — user-service and order-service — each in its own container:

// Run user-service on port 5000
docker run -d -p 5000:5000 user-service

// Run order-service on port 5001
docker run -d -p 5001:5001 order-service

You can now access each service independently using localhost ports.

With Docker installed and the basics covered, you're now ready to begin designing microservices architecture. In the next section, we’ll discuss identifying and structuring microservices in your applications.
