How To Install and Use Docker Compose on Ubuntu 20.04

Step 1 — 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

Next, set the correct permissions so that the docker-compose command is executable:

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

To verify that the installation was successful, you can run:

docker-compose --version

You’ll see output similar to this:

Output
docker-compose version 1.29.2, build 5becea4c

Step 2 — Setting Up a docker-compose.yml File

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

mkdir ~/compose-demo
cd ~/compose-demo

In this directory, set up an application folder to serve as the document root for your Nginx environment:

mkdir app

Next, create the docker-compose.yml file:

nano docker-compose.yml

Insert the following content in your docker-compose.yml file:

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