New (squashed) image not saved #170

JavaChr1s · 2018-05-22T06:31:17Z

I already used docker-squash a couple of times without any problem, but now the new images wasn't saved.

The image is used to be a oracle database. We do the following:

created the image
added some data to the database
docker squash
used the image => container
for each new version we commit the container
docker squash
used the image => container
for each new version we commit the container
docker squash
and so on

That worked for some versions, but now it stopped working. The squashed image is just not saved, but I can't see any error in the log.

osp@host01:~$ docker-squash -t osp-common-docker-local.artifacts.host.de/database:1.24.0 osp-common-docker-local.artifacts.host.de/database:1.24.0raw -v

me too!! no new image generate

goldmann · 2018-06-11T14:26:46Z

Is there any chance for a reproducer? I don't see any errors in the log and Docker daemon even confirmed with status 200 that the image was uploaded, so I'm not sure what could be wrong here really.

This could be potentially related to some changes in Docker itself. What versions you use exactly and from where you got them? I assume this is Docker CE, version 18+. If that's the case, can you try to squash it using older Docker?

ZmingZinnia · 2018-06-12T09:24:33Z

it's same for Docker version 17.12.1-ce

Have you tried specifying the -f flag? try to squash latest 3 or 5 layers. I wonder if it has anything to do with the fact that you squash all layers.

Generally speaking, squashing everything together can be viewed as a bad practice. Best practice is to squash everything that is part of the Dockerfile, leaving the image you base on, untouched.

goldmann · 2018-06-13T09:55:22Z

OK, I must admit that this is more than weird. Can you give me the last lines of the log, building with -v after "New squashed image ID" line? I'm pretty sure the Docker API returns code 200, otherwise we should have an exception thrown. And if it return 200 then it ACKs the image...

andreyto · 2018-09-08T20:06:23Z

I was having this same issue until I have increased the sizes of the file systems that were holding both /tmp and /var/lib/docker. docker-squash uses both locations. They were getting nearly full in my case, and the output image would not show up in docker images, despite successful completion messages from docker-squash. After growing both file systems, the problem resolved itself.

goldmann · 2018-09-08T21:02:40Z

This is a very valuable finding worth investigation on my end. Thank you!

ximencx · 2019-10-28T16:02:58Z

@zMingGit i have some issue,,what is your docker version??

fty1777 · 2024-11-15T14:22:16Z

I just met the same problem. I guess the root cause of the problem is that when docker-squash try to load the squashed image, the disk is full and the load silently (at least docker-squash is not aware of it) failed. I solved the problem by using the --output-path arg to save the squashed image into a file on another hard drive first, removing the original image, and then docker loading the squashed image back from the file.
