To install Compose V2 for the active user under the $HOME directory, follow these steps:

Docker Compose V2 Installation Official Guide

1.Set up Docker Config Directory

   DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
   mkdir -p $DOCKER_CONFIG/cli-plugins

2.Download Docker Compose V2

   curl -SL https://github.com/docker/compose/releases/download/v2.23.0/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose

If the download is too slow, you can download the file separately and upload it to your server, then move it to /root/.docker/cli-plugins and name it docker-compose to skip the above command.

   mv docker-compose-linux-x86_64 /root/.docker/cli-plugins/docker-compose

Grant Execute Permission

chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
