How To Uninstall Docker and Docker Compose On Linux Mint

Step 1: Remove Docker Packages

Open a terminal and run the following command to list all installed Docker packages:

$ dpkg -l | grep -i docker

This will show you a list of Docker-related packages installed on your system. Thereafter you can use the following command to remove those packages:

$ sudo apt-get purge -y docker-engine docker docker.io docker-ce docker-ce-cli

Step 2: Remove Docker Images, Containers, and Volumes

You must comprehend that removing Docker packages doesn't remove your Docker images, containers, and volumes. Therefore if you want to completely remove Docker, including all its data, run the following commands:

Caution: This will delete all your Docker data, including containers, images, and volumes. Make sure you have backed up any necessary data.

$ sudo rm -rf /var/lib/docker

Step 3: Remove Docker Compose

If you have Docker Compose installed, you may want to remove it as well. Use the following command:

$ sudo rm /usr/local/bin/docker-compose

Step 4: Remove Docker Group

By default, Docker adds your user to the "docker" group. If you want to remove this group, run the following command:

$ sudo groupdel docker

Step 5: Verify Uninstallation

You can check if Docker has been completely removed by running the following command:

$ docker --version

If Docker has been successfully uninstalled, this command should return a "command not found" or No such file or directory message.

That's it! Docker should now be uninstalled from your Linux Mint system.
