COMPLETELY Uninstall Docker in Ubuntu [100% Working]


Docker is one of the well-known containerization tools which is widely used in most organizations. Docker helps the developer build, test and deploy their application seamlessly across various environments. It is one of the best offerings and an important tool in the area of DevOps.

In a few cases, you might not be willing to use docker and you may want to uninstall Docker from your system. How do we do that?

In this article, let us understand how to uninstall Docker on Ubuntu OS. Let us get started.


Step-1: Removing Docker Images, Containers, Volumes, and Configurations

Docker utilizes images as blueprints for applications, containers as running instances, volumes for persistent storage, and configurations to customize behaviors.

Remove docker images

docker rmi $(docker images -a -q)

Remove all exited docker containers

docker rm $(docker ps -a -f status=exited -q)

Remove running docker containers by first stopping them and later removing them

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

Remove all docker networks

docker network prune

The docker system prune -a command cleans up unused Docker components, freeing space but also potentially resulting in data loss. Care should be taken before executing cleanup commands to ensure critical data is backed up.

docker system prune -a

The command docker system prune -a is a powerful tool that removes:

  • All stopped containers
  • All networks not used by at least one container
  • All volumes not used by at least one container
  • All images without at least one container associated with them
  • All build cache


Step-2: Delete the Docker packages

You must know the available docker packages before deleting them. Let us list all the available docker packages on our system with the command

$ dpkg -l | grep -i docker

Sample Output:

root@host01:~$ dpkg -l | grep -i docker
ii docker-buildx-plugin 0.10.4-1~ubuntu.22.04~jammy amd64 Docker Buildx cli plugin.
ii docker-ce 5:24.0.1-1~ubuntu.22.04~jammy amd64 Docker: the open-source application container engine
ii docker-ce-cli 5:24.0.1-1~ubuntu.22.04~jammy amd64 Docker CLI: the open-source application container engine
ii docker-ce-rootless-extras 5:24.0.1-1~ubuntu.22.04~jammy amd64 Rootless support for Docker.
ii docker-compose 1.29.2-1 all define and run multi-container Docker applications with YAML
ii docker-compose-plugin 2.18.1-1~ubuntu.22.04~jammy amd64 Docker Compose (V2) plugin for the Docker CLI.
ii python3-docker 5.0.3-1 all Python 3 wrapper to access's control socket
ii python3-dockerpty 0.4.1-2 all Pseudo-tty handler for docker Python client (Python 3.x)

Upon identifying the docker packages, now go ahead and delete them using the below command

sudo apt-get purge docker-ce docker-ce-cli

You will notice that the docker packages will be deleted upon execution of the command.

Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:*

After this operation, 158 MB disk space will be freed.

+ rm -rf /var/lib/docker/buildkit /var/lib/docker/containers /var/lib/docker/image /var/lib/docker/network /var/lib/docker/ /var/lib/docker/overlay2 /var/lib/docker/plugins /var/lib/docker/runtimes /var/lib/docker/swarm /var/lib/docker/tmp /var/lib/docker/trust /var/lib/docker/volumes

Uninstalling docker will not delete all the docker stuff. Hence, you must remove the docker images, containers, volumes, and other configurations that you created since they are not removed automatically.

In this section let us understand how to remove docker images, containers, volumes, and networks.

If you do not want to remove the docker images, containers, volumes, and network that are created one by one, then you can jump to Step-7 discussed in the next section which also does the cleanup.


Step-3: Deleting the remaining docker files

You can execute the commands to completely remove docker and its related files from your system.

All the docker files will be in the /var/lib/docker path so you have to remove the folder.

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

Delete the docker group that you have created in order to run the docker as non-root user or without sudo

sudo groupdel docker

Delete the docker socket using the command below

sudo rm -rf /var/run/docker.sock

In case you have docker-compose installed, delete that using the command below

sudo rm -rf /usr/local/bin/docker-compose
sudo rm -rf /etc/docker
sudo rm -rf ~/.docker

With this, the uninstallation of docker will be successful. You can verify if the docker has been uninstalled by typing $ docker command

Upon successful uninstallation of docker, you will see the below output.


bash: /usr/bin/docker: No such file or directory

This confirms that Docker is no longer available in your system. In case you want to use Docker, you have to re-install it on your system.


Step-4: Removing Docker User Group

Docker often creates a user group named docker. Provide a command to delete it:

sudo groupdel docker


Step-5: Cleaning Up Unused Packages

Recommend running:

sudo apt-get autoremove

This command removes packages that were installed as dependencies and are no longer used and that's it, you have successfully removed docker from your system.
