Uninstall Docker Ubuntu

Uninstalling Docker on Ubuntu is a straightforward process that can be completed in a few simple steps. Whether you're looking to free up disk space or switch to a different containerization platform, this guide will walk you through the uninstallation process. Read on to learn how to remove Docker from your Ubuntu system.

Removing Docker on Ubuntu

To uninstall Docker on Ubuntu, you can follow these steps:

1. Stop Docker containers and services

   Before uninstalling Docker, it is important to stop any running Docker containers and services. This ensures that the uninstallation process goes smoothly without any interruptions. You can do this by running the following command:

   sudo systemctl stop docker
   

2. Remove Docker packages

   Next, you need to remove the Docker packages from your system. Ubuntu uses the Advanced Packaging Tool (APT) for package management. To uninstall Docker, run the following command:

   sudo apt-get purge docker-ce docker-ce-cli containerd.io
   

   This command removes the Docker packages along with their configurations and dependencies.

3. Delete Docker files and directories

   After removing the Docker packages, there might be leftover files and directories that need to be deleted. These files include Docker images, containers, volumes, and network settings. To delete these files, run the following commands:

   sudo rm -rf /var/lib/docker
   sudo rm -rf /etc/docker
   

   The rm -rf command recursively deletes the specified directories and their contents.

4. Remove Docker data

   If you want to completely remove all Docker data from your system, including images, containers, and volumes, you can use the following command:

   sudo rm -rf /var/lib/docker
   

   Make sure to use this command with caution, as it permanently deletes all Docker data and cannot be undone.
