That script requires only standard nix tools and provides auto-updates, without additional dependencies
curl -o ~/bin/docker-compose -s https://raw.githubusercontent.com/titanium-codes/docker-compose/master/docker-compose && chmod +x ~/bin/docker-compose
NOTE: You can download script in any location (which included in
$PATH), but updater will try to edit script file when new docker-compose version will be released. That means, that you should have write permissions to target file, the best way is to place script in your home folder.
Same as docker-compose
Script will check updates every day, if new version will be released, script will update itself and download new docker/compose image
