How to Uninstall/Remove Docker Containers on Nvidia Jetson Orin Nano

Issue Overview

Users are encountering difficulties when attempting to uninstall or remove Docker containers from the Nvidia Jetson Orin Nano, specifically when using the NanoOWL application. The main symptoms reported include:

• Inability to find reliable resources or commands for uninstalling Docker containers.
• Confusion regarding the complete removal of Docker containers and their associated files.
• The issue arises during the process of freeing up storage space while testing different models.

The context of this problem is primarily during setup and maintenance phases, as users seek to manage their storage effectively. The hardware in question is the Nvidia Jetson Orin Nano, and the software includes Docker along with the NanoOWL application. Users have expressed frustration over the lack of clear documentation tailored to their specific needs, leading to a negative impact on their user experience and system functionality.

Possible Causes

Several potential causes for the difficulties in uninstalling Docker containers may include:

• Lack of Documentation: Many users report that existing resources do not adequately address how to manage Docker on the Jetson Orin Nano.

• Configuration Errors: Users may inadvertently misconfigure their Docker setup, leading to complications during uninstallation.

• Software Bugs: There could be bugs within the Docker application or its integration with the Jetson platform that complicate the uninstallation process.

• User Errors: New users may not be familiar with command-line operations or Docker’s architecture, leading to mistakes during the uninstallation process.

These factors contribute to the challenges users face when trying to remove Docker containers and free up storage.

Troubleshooting Steps, Solutions & Fixes

To assist users in effectively uninstalling Docker containers from their Nvidia Jetson Orin Nano, follow these comprehensive troubleshooting steps:

1. Check Installed Containers:

   • Open a terminal on your Jetson Orin Nano.
   • Run the following command to list all running and stopped containers:

     docker ps -a
     

2. Stop Running Containers:

   • If you have any running containers that you want to stop, use:

     docker stop <container_id>
     

   • Replace <container_id> with the actual ID of your container.

3. Remove Containers:

   • To remove a specific container, use:

     docker rm <container_id>
     

   • For removing all stopped containers at once, run:

     docker container prune
     

4. Remove Docker Images:

   • To free up additional space, you may also want to remove unused images:

     docker rmi <image_id>
     

   • To remove all unused images, run:

     docker image prune
     

5. Remove Volumes:

   • If you have associated volumes that you no longer need, you can remove them with:

     docker volume rm <volume_name>
     

   • To remove all unused volumes, use:

     docker volume prune
     

6. Uninstall Docker Completely (if needed):

   • If you wish to uninstall Docker entirely from your system, execute:

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

   • Follow this by removing all images and containers:

     sudo rm -rf /var/lib/docker
     

7. Check Disk Space:

   • After performing these actions, check your disk space to confirm that space has been freed up:

     df -h
     

8. Best Practices for Future Management:

   • Regularly monitor your installed containers and images.
   • Utilize commands like docker system df to check disk usage by Docker.
   • Familiarize yourself with Docker’s documentation for best practices in managing containers.

By following these steps, users should be able to successfully uninstall or remove Docker containers and manage their storage more effectively on the Nvidia Jetson Orin Nano. If issues persist after following these instructions, further investigation into specific error messages or behaviors may be required.
