[russellgan]

Expected behavior
container-diff diff daemon://<local_image1> daemon://<local_image2> --type=file

Actual behavior
fails with fatal error

Steps to reproduce the behavior
container-diff diff daemon://<local_image1> daemon://<local_image2> --type=file

I know a lot people have the same issue.So does anyone know other tools like container-diff which can explore file tree and export.PLEASE TELL ME!thanks a lot!!!

@russellgan thanks for the issue. could you provide a little more detail on the image you're trying to run on? I'd love to be able to repro this so we can figure out a way to fix the problem.

@nkubala thank you for replying.The image I compare is a private image from the company i am working at.So I'm sorry i can't give you more detail about it.But what I can tell you is size of image is about 5g.And before analyzing there is around 12g free memory,but still not enough.To be honest,I deeply doubt if this could be a problem caused by tool itself.

Hello, i'm having the exact same issue on my side using 0.16.0 release on ubuntu 20.04 amd64
Playing with the diff options on 2 large docker images (~15Gb each)

my debug logs

container-diff diff daemon://myimage1:testdaemon://myimage2:test --type=history -v debug
INFO[0000] starting diff on images daemon://myimage1:test and daemon://myimage2:test, using differs: [history] 
INFO[0000] retrieving image: daemon://myimage2:test
INFO[0000] retrieving image: daemon://myimage1:test

Then the program exit with this message 5 minutes after:
[1] 68808 killed container-diff diff daemon://myimage1:test --type=history -v debug

And using dmesg I have this message :

If it helps, this happened for me with discourse/base for a repro, but my machine is also memory constrained (4gig total)

just got hit by the same error, OOM

For me this issue is not there if passing .tar files of docker image to the program.
