June 28, 20233 yr I am getting this in Fix Common Problems: Docker image file is getting full (currently 90 % used) You should either increase the available image size to the docker image here [DOCKER SETTINGS] or investigate the possibility of docker applications storing completed downloads / incomplete downloads / etc within the actual docker image here: [DOCKER] More Information I don't see anything that will let me increase it under docker settings. Please help a dummy out! I am not able to upgrade my docker images, I assume because I'm out of space.
June 30, 20233 yr Community Expert How large is your current docker.img? 20G is often more than enough. Maybe you need to figure out what is filling it instead of increasing its size,
July 13, 20233 yr Author I set up Unraid and Docker awhile ago following videos. Fortunately, it has just worked since. Unfortunately for me, I have forgotten how it works. How do I find out what is filling it?
July 13, 20233 yr Author Solution I found what I need here. It turns out I just have too many docker containers.
February 22, 20242 yr Just resurrecting this conversation for a moment. I know I can 'simply' increase the size, however, I also know it isn't necessarily the right way. I have a total of 9 images, which are taking up a total of 15gb. I have my suspicions on the culprit but wanted to find out for sure. I grabbed and ran the script in this video but it is not showing me one of the important sections..."List of docker volumes, the container which they are connected to their size". I will note that I am running UR, v.6.12.8. and, it should also be noted that I am running with datasets (ZFS), which I suspect is causing the problem...
February 22, 20242 yr Community Expert If usage isn't growing then I would say there is nothing to fix. Make it a little bigger if you want to have some room for more containers.
May 17, 20242 yr 1 You can view how large each docker container is: Go to docker tab of unraid, near the bottom of the page there is a button called [Container Size] it's next to the update all containers button 2 You can do the following terminal commands: List docker volumes (these are internally stored data volumes created by docker containers you are running) docker volumes ls List size of docker volumes that might be taking up space du -h -d 1 /var/lib/docker/volumes Delete unused docker volumes: docker volume prune Inspect a docker volume docker volume inspect <name_of_volume> Manually delete a docker volume (use with caution) cd /var/lib/docker/volumes ls rm -r <folder name> 3 You can use user-scripts plugin: user scripts plugin here The default scripts included are: - Delete any dangling images from the docker.img file - Display the size of the docker container's log files (to see if a docker app is filling up the image file through excessive logging) And you can also add the following scripts from here - Clean Docker Logs - Get size of running containers Edited May 17, 20242 yr by kiwijunglist
July 26, 20241 yr I would like to add into this one that the addition of some of the new AI containers have brought us to a point where increasing the size of the docker image is now a thing to do. I have mine on a twin SSD cache and it screams. well worth it. I upped mine to 60Gig and it still wasn't enough to handle the LocalAI docker install. (I also have EasyDiffusion installed as well) LocalAI installs an easy 16Gigs of downloads and then extracts them. It's huge. (edit) after the LocalAI install finally worked with the larger Docker image it them proceeded to download a lot more data. Another huge amount. I really suggest at least an 80Gig Docker image for these massive docker images Edited July 26, 20241 yr by Dick Dawson
January 2, 20251 yr Come on. This is the first result on google when searching for "unraid increase docker image". There's even people saying that they successfully increased the size. And still the question is not answered. When someone ask "How do I increase the size of the docker image?" Why answer "that's not the best solution"? Just answer the question, please. Edited January 2, 20251 yr by Hache
January 2, 20251 yr Community Expert Because many people who ask that question actually need a different solution to their problem.
February 25, 20251 yr My Docker file was getting full (I genuinely believe there's nothing wrong, just have many containers), so I disabled Docker, increased the vDisk size, enabled Docker again and nothing changed. The Unraid dashboard still reports the same 70%+. Is there anything else that needs to be done?
February 26, 20251 yr Community Expert What did you increase it from? Those Container Size totals are nearly 70% of 50G so not clear what you are expecting.
February 26, 20251 yr 5 hours ago, trurl said: What did you increase it from? Those Container Size totals are nearly 70% of 50G so not clear what you are expecting. I initially increased it from 20G to 50G and have now expanded it further to 70G. The point is that nothing changes and the dashboard continues to show 71%. Additionally, when I hover over the 71% it shows "69.7 GiB", which is yet another number I don't understand the origin of. That said, I am not suggesting that the Docker utilization percentage in the dashboard is incorrect. When I update Docker containers the utilization temporarily increases to 72%-73% as images are downloaded and then drops back down after orphaned images are cleaned up. It's just I don't seem to understand how this thing works.

April 16, 20251 yr As of Unraid v7: 1. Go to the Docker tab, then Stop All containers. 2. Go to the Settings tab, then select "Docker". 3. Change "Enable Docker" to "No". This stops the Docker service. 4. The "Docker vDisk size" option should now become available. 5. Increase this to your desired volume size (ie: 30GB). When you're done, change "Enable Docker" back to "Yes", then start your containers again. Edited April 16, 20251 yr by shooks

I'm hoping to start using some MLL containers soon, so will likely need to expand for those, but before I do, I'd like to make sure there's no issues with what I have now.Edit: Paging @trurl - are you able to help with this?

November 1, 2025Nov 1 I think something that I haven't seen mentioned here or maybe it was an I missed it but you should be mountain a share in you docker localAI config to store the models. This should preferably be on a nvme ssd. at the bottom of every config page for a docker container in unraid there is a area where you can add addition storage and ports to configure you should create a share for you models then app that in the config to something like /models in the container and int he config of the software set that as the model download location. this should eliminate virtually all of you bloat and I would suspect that you have something similar going on with you other containers as well. Aside for the actual models there should be almost no space eaten up by this container. If it can be helped you should almost never store data in the docker image.
November 26, 2025Nov 26 Small question, will changing the size (turn off and on docker service to do increase it) cause me to need to reinstall my containers?

One involves just adding text which could be implemented very easily.So easy, but no one thinks of the newbs. Please help the newbs. It could be implemented today.Surely the moderators here know how many newbs ask "How can I change the vDisk size????".UNRAID's goal should be to make the software as easy as possible. Burying the size change information in the stopped Docker makes no sense from the newb's perspective. Edited February 7Feb 7 by digitaldoctor
February 7Feb 7 Community Expert @digitaldoctor If I remember correctly you can change the docker vdisk size without disabling docker as long as you stop the array.

Probably worse.The UNRAID UI was made from the perspective of the elite coders that make the underlying code, NOT the perspective of a newbie new user. Herein lies the problem.
