Docker Compose is an Effective tool for running Multiple containers by passing multiple parameters in a YAML format/file and can simply be run as docker-compose up and docker-compose down.
Ideally, when you run a docker container out of the docker image it can be helpful for running a single container with fewer parameters, but Just assume if you need to run multiple containers with passing several parameters, like passing Environmental Variables, Volumes, Networks, linking containers, etc then docker compose is very helpful.
It Creates the entire environment based on the YAML file you have created and also it’s easy to delete exactly the same thing what you have created from docker compose itself.
So let’s see the Installation procedure of Docker Compose. make Sure your Server has Docker Installed.
ubuntu@devopsage:~$sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
