Today I am writing how to completely remove / uninstall the docker and it's components properly from my ubuntu linux vm hosted on proxmox. I will run all the commands as root, if you don't have root permission, please switch to root or sudoers user for continue without any errors.
First I need to stop any existing container if running:
- docker stop [container name / ID]
- This command stops the container with the specific name or docker container IDs
- docker rm [container name / ID]
- After stopping the container I need to rm the container one by one or I can remove multiple container at a time
After stopping and removal of the containers I am going to remove the volumes where all the containers and docker images stored.
- docker system prune --volumes
- Will remove all the image files and data related to docker containers
Now I am going to stop the docker and after that will run the commands to remove all docker installed files on the system.
- sudo systemctl stop docker
- This will stop the docker services on the system
- sudo apt-get purge docker-ce -y
- This command will remove all docker application
- sudo apt-get autoremove --purge docker-ce -y
- Will purge docker completely
- sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras
- And this command is as optional or you can use as alternatives of above. During the run of this command you need to press y to accept the uninstallation process
And finally I will remove all the leftover folders created for docker on the /etc/ and /var/lib folder.
- rm -rf /etc/docker
- rm -rf /var/lib/docker
Finally I need to check the docker with status commands
- sudo systemctl status docker
- If you see: "Unit docker.service could not be found - means you have successfully uninstalled / removed docker and it's services completely from your ubuntu linux system.
