If you are looking to uninstall Docker from your CentOS system, you've come to the right place. In this article, we will walk you through the step-by-step process of removing Docker from your CentOS machine.
Why Uninstall Docker?
There can be various reasons why you may want to uninstall Docker from your CentOS system. It could be due to issues with the current installation, the need to switch to a different containerization platform, or simply because you no longer require Docker for your specific use case.
Whatever the reason may be, this guide will help you uninstall Docker from your CentOS system effectively.
Step 1: Stop Docker Containers
Before removing Docker from your CentOS system, it is crucial to stop all running Docker containers. This ensures that there are no active processes or dependencies that may interfere with the uninstallation process.
To stop all running Docker containers, use the following command in your terminal:
docker stop $(docker ps -a -q)
Step 2: Remove Docker Containers
Once all Docker containers are stopped, you can proceed to remove them from your system. To remove all containers, use the following command:
docker rm $(docker ps -a -q)
This command removes all Docker containers, ensuring a clean environment for the uninstallation process.
Step 3: Uninstall Docker Engine
To uninstall Docker Engine, you need to remove the Docker package from your CentOS system. This can be done using the package manager,
yum, with the following command:
sudo yum remove docker-ce
This command will remove the Docker Engine package from your system, including all associated files and configurations.
Step 4: Remove Docker Images
In addition to Docker containers, it is important to remove any Docker images that may have been downloaded or created on your system. To remove all Docker images, use the following command:
docker rmi $(docker images -a -q)
This command removes all Docker images, freeing up disk space on your CentOS system.
Step 5: Clean up Docker Artifacts
To ensure a complete uninstallation of Docker from your CentOS system, it is recommended to clean up any residual artifacts. This includes removing Docker volumes, networks, and other resources.
To remove Docker volumes, use the following command:
docker volume prune
To remove Docker networks, use the following command:
docker network prune
By cleaning up these artifacts, you can ensure a thorough removal of Docker from your CentOS system.
Uninstalling Docker from your CentOS system is a straightforward process that requires a few simple steps. By following this step-by-step guide, you can successfully remove Docker and all related components from your CentOS machine.
