How To: Docker: Install Docker Compose

Installing Docker Compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

docker-compose --version

Setting Up a docker-compose.yml File

Create a web server environment using the official Nginx image from Docker Hub, the public Docker registry. This containerized environment will serve a single static HTML file.

Start off by creating a new directory in your home folder, and then moving into it:

~/compose-demo/app/index.html
~/compose-demo/docker-compose.yml

docker-compose.yml

version: '3.7'
services:
    web:
        image: nginx:alpine
        ports:
            - "8000:80"
        volumes:
            - ./app:/usr/share/nginx/html

Running Docker Compose

To start up Docker Compose environment

docker-compose up -d

To verify that the container is active, you can run:

docker-compose ps

Enable Docker
