Let's set up docker...

Installation and setup of docker & docker-compose to a linux machine

Installation of docker, here we are assuming a Ubuntu machine.

Let us first remove existing docker files if any are present in the system

sudo apt-get remove docker docker-engine docker.io

Now let's update our packages before we go ahead

sudo apt-get update

Now we are going to install docker.io which is the Debian package for docker

sudo apt install docker.io

Depending on your machine's internet connection speed and other factors, this may take some time. After the installation is complete, you can run the command the following command to check if docker is running or not.

sudo docker ps -a

You might notice that you need to be a sudo to run this command, which can be a hindrance in the long run, so let's allow the user to run docker commands without using sudo, to do this run the following command

sudo usermod -aG docker $USER

replace $USER with your username, please ensure that the user should be a sudoer

Now to install docker-compose

Download the latest stable release of the docker-compose standalone

sudo curl -SL https://github.com/docker/compose/releases/download/v2.24.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

This can change over time so get the current version from https://docs.docker.com/compose/install/standalone/

Once downloaded, give executable permissions to the binary

sudo chmod +x /usr/local/bin/docker-compose

This should be it, test whether docker-compose is installed by running the below command

docker-compose --version

If this doesn't work, try to create a symbolic link to /usr/bin/

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

and that is it, you have successfully installed docker & docker-compose to your Linux system, enjoy dockerizing stuff
