August 1, 201510 yr My docker 10GB .img just filled all the way up today. Is there a certain command to give it more space?
August 2, 201510 yr Settings / Docker Stop Docker Delete the existing image file Recreate the image file with a greater size, and enable docker Add your containers again via "Add Container", and select all of your "my*" containers you were using. After all the downloads happen again, it will be like nothing happened.
August 2, 201510 yr Author Awesome, I was guessing that was the case. Thanks for your reply. As it turned out, the real reason was the SSD ran out of space not the docker.img. I just setup a new windows 10 VM and got a little carried away installing new things. Then all of the sudden I couldn't access some of my dockers. Ended up moving some stuff off the SSD and problem solved.
August 3, 201510 yr Do you really have to delete the img file and reinstall all the dockers? It's been a while, but I kinda remember just stopping docker, changing the img size and restarting it. I think unRaid just added more blank bits using the dd command and expands the file. I don't think I had to reinstall anything. But like I said, that was a while back and my memory ain't what it used to be :-)

August 3, 201510 yr So you're not gonna go to 21G just for the love of science and experimentation? And what about shrinking the img? I think these questions demand an answer!!! I elect sparklyballs for the testing
August 3, 201510 yr ok... I took one for the team. Stop docker. Increase the size. Restart docker. Done Not in the mood however to decrease the size. Sparkly can handle it.
August 3, 201510 yr Author Stop docker. Increase the size. Restart docker. Done Fancy, wait... flared pinky fancy. UnRAID has definitely come a long!
August 3, 201510 yr You still want to go through the process of deleting it all since you dont know what possible corruptions were caused from hitting the absolute limit.
August 4, 201510 yr I was under the impression previously we could expand but not shrink a docker image file without deleting it first?!? Kryspy

August 4, 201510 yr I've hit the limit twice and ended up with a corrupted docker image. Should be ok with the 30G I've allocated now..
August 4, 201510 yr Author 30G I've allocated now.. I think you're having way to much fun with docker!

August 4, 201510 yr This seems an appropriate place to ask the following... What is the best way to manage the docker's increasing size? My docker size has been increasing. I do update dockers when available, does this mean garbage is being left behind every upgrade? If the above is true, is the only way to manage the increasing size to remove the docker container+image, and re-add? (other than increasing the docker size itself). Thanks

If the above is true, is the only way to manage the increasing size to remove the docker container+image, and re-add? (other than increasing the docker size itself). Thanks To manage docker size properly: 1) Do not update dockers 2) Do not run auto-updating dockers 3) Do not install/uninstall/install/uninstall dockers 4) Periodically scrub your docker using the UI Settings/DockerSettings page My docker size is 654 megs in use after 5.5 weeks of use, when initial base size after first creations was around 645 megs. I run the following 3 dockers: EggDrop, NzbGet, and a torrent program. For those who update too frequently or use auto-updating programs the following step is required: 5) Nuke From Orbit periodically to restart back to pristine condition.
August 5, 201510 yr That advise is even worse than I expected. I just came across your docker maintenance thread http://lime-technology.com/forum/index.php?topic=37407.0 here, too. What's LT official response been on this? Seems to be a pretty big flaw
