How to enable docker without having the containers I have set to auto-run, run?

[sunwind]

Obviously with docker disabled I can't edit the autostart options on the page. How do I do this? or a way to erase the autostart options in cli or editing a file?

/var/lib/docker/unraid-autostart

 

Which is inside the docker.img file, so if that's not mounted you will need to manually mount it to make the edit. Or you can just delete the docker.img file and recreate it, you will need  to recreate any custom networks before restoring all you containers with the previous apps section of CA. It only takes a few minutes, and you won't lose any data as long as your containers are properly mapped to appdata.

To add some more specific details/steps to this; here's what I did just now (Ref) :

• Made a backup of the `docker.img` file, just in case

• Mounted the `docker.img`, and removed the containers from autostart:

  • /mnt# mkdir /mnt/docker_img
    
    /mnt# mount -o loop /mnt/disk6/TempDumpBackups/docker.img /mnt/docker_img
    
    /mnt# cd /mnt/docker_img/
    
    /mnt/docker_img# ls
    btrfs/    buildkit/    containers/  image/    plugins/   swarm/  trust/   unraid-autostart           volumes/
    builder/  containerd/  engine-id    network/  runtimes/  tmp/    unraid/  unraid-update-status.json
    
    /mnt/docker_img# file unraid-autostart
    unraid-autostart: ASCII text
    
    /mnt/docker_img# cat unraid-autostart
    this
    has
    a
    list
    of
    autostart
    docker
    containers
    
    /mnt/docker_img# cp unraid-autostart unraid-autostart.bkup
    
    /mnt/docker_img# echo "" > ./unraid-autostart
    
    /mnt/docker_img# cd /mnt
    
    /mnt# umount /mnt/docker_img

     

• Set 'Unraid -> Settings -> Docker -> Enable Docker' to 'Yes'

• Made the changes I needed to make:

  • On the 'Docker' tab, for each container, checked/updated any mappings directly on `/mnt/cache/*` (eg. `/mnt/cache/appdata`) and updated them to `/mnt/cache_250gb/*` (eg. `/mnt/cache-250gb/appdata`), clicked 'Apply' (since 'Save' doesn't seem to update the mappings in the Unraid Web UI), then manually stopped the container again.

• Set 'Unraid -> Settings -> Docker -> Enable Docker' to 'No'

• Mounted the `docker.img`, and restored the previous autostart containers:

  • /mnt# umount /mnt/docker_img
    
    /mnt# mount -o loop /mnt/disk6/TempDumpBackups/docker.img /mnt/docker_img
    
    /mnt# cd /mnt/docker_img/
    
    /mnt/docker_img# rm unraid-autostart
    
    /mnt/docker_img# mv unraid-autostart.bkup unraid-autostart
    
    /mnt/docker_img# cd ..
    
    /mnt# umount /mnt/docker_img
    
    /mnt# rm -r /mnt/docker_img/
