Docker Compose

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

I heavily utilize Docker Compose in my environment. I find it much easier to deploy Docker containers and, of greater importance, to document, update and make changes to my production containers and stacks.

I also use Portainer for some container management. However, I use it primarily for restarting or stopping containers and for development and testing purposes.

Installation

To make sure you obtain the most updated stable version of Docker Compose, you’ll download this software from its official Github repository.

First, confirm the latest version available in their releases page. At the time of this writing, the most current stable version is 2.3.3.

Use the following command to download:

mkdir -p ~/.docker/cli-plugins/
curl -SL https://github.com/docker/compose/releases/download/v2.3.3/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
