Help with Docker - not running and cannot uninstall

  • I recently developed a need to set up Docker on my OMV NAS as described below:



    After reading numerous recommendations I did the following:

    1. created a shared folder on the NAS to use for Docker [/srv/dev-disk-by-label-Data/Docker] As my OS is on a 32GB SSD
    2. I set the ACL for this folder to allow Docker to Read and Write
    3. In the Docker setup page I added the shared folder to the Docker Storage field
    4. I changed the IPTables to use Legacy
    5. I saved that configuration
    6. I Installed Docker

    The result of this is that Docker shows that it is installed but not running (even after numerous Docker Restarts and a couple of Server Reboots.

    Furthermore I thought perhaps I should just Remove Docker and Re-install but in doing that I get an error message saying Docker Cannot be uninstalled.



    Also the boot log held these gems if they may help:

    I am not sure how OMV_Extras caused this to happen but I would appreciate any assistance in correcting this problem.

  • ShamusLit I'm curious why you changed your IPTables to legacy, and what you mean by “I set the ACL for this folder to allow Docker to Read and Write”
