November 7, 20214 yr Im starting to run low on space in my docker image, and while Im sure it has been covered before I cant seem to find it. How would I go about increasing the size of my docker image? Thanks in advance.
November 7, 20214 yr Settings - docker. Stop the service and then increase the size and restart the service. Just a ton of containers or is there a problem with it constantly growing?
November 7, 20214 yr Author Just a lot of containers. And I probably didn’t make the initial size big enough As I think it’s only 20 gig
November 8, 20214 yr Here's the specific post that provides the answer you need, and many others. Just did this yesterday myself and worked well.

Some people may need it to be somewhat larger than 20G, but most don't, and if your docker.img usage is growing that means you have apps writing into docker.img instead of to mapped storage. Making docker.img larger won't fix that, it will only make it take longer to fill.

Making docker.img larger won't fix that, it will only make it take longer to fill. You're very right. I didn't mention it since the OP said in the post above mine that they simply have "a lot of containers" and not an issue with growth. But for anyone else ending up in this thread, it's worth mentioning that understanding docker.img growth is also touched on in the FAQ.
