Install Docker Compose on Linux systems



On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub. Follow the instructions from the link, which involve running the curlcommand in your terminal to download the binaries. These step by step instructions are also included below.
1. Run this command to download the latest version of Docker Compose:



sudo curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose





Use the latest Compose release number in the download command.
The above command is an example, and it may become out-of-date. To ensure you have the latest version, check the Compose repository release page on GitHub.
If you have problems installing with curl, see Alternative Install Options.

Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose 
Optionally, install command completion for the bash and zsh shell. 
Test the installation.
docker-compose --version
