Docker Compose is a toolset provided officially by Docker for managing multi-container projects, with many popular Docker projects relying on Docker Compose for operation, such as the password management tool Bitwarden. By default, Docker Compose is not installed alongside Docker. This guide uses an Ubuntu 20.04 cloud server as an example to illustrate the installation process for Docker Compose.

Since Docker Compose depends on Python and the pip package manager, it is necessary to install these two components first.

$ sudo apt install -y python3 python3-pip

Then, use pip to install Docker Compose.

$ sudo pip3 install docker-compose

Check the version of Docker Compose to verify that the installation was successful.

$ docker-compose -v
