Broken since docker 26

[sbp-bvanb]

What happened:

Github ubuntu 20.04 updated the docker version from 24 to 26

What you expected to happen:

dive continued to work

How to reproduce it (as minimally and precisely as possible):

Run dive with docker 26

Anything else we need to know?:

Environment:

• OS version
• Docker version (if applicable)

Fetching image... (this can take a while for large images)
cannot fetch image
could not find 'blobs/sha256/whatever' in parsed layers

For me this seems to be related to containerd storage engine. I think it brokes as I switched to it.

I agree re. containerd storage engine. I had containerd enabled on Docker Desktop with Docker v26.1.4 on Windows 11 with WSL2 - it was broken with containerd enabled but disabling containerd fixed it. It would be helpful if it was compatible with containerd though.

Anyone know how to download and run a earlier docker version on mac? Brew only has the latest version. I tried downloading from https://download.docker.com/mac/static/stable/aarch64/but got "“docker” can’t be opened because Apple cannot check it for malicious software. when I tried running it.

ah found the install instructions: https://docs.docker.com/engine/install/binaries/

In my case running xattr -rc docker fixed the error I was getting

Disabling containerd in Docker Desktop settings on OSX has fixed it for me. (With latest version of Docker Desktop : Docker version 27.0.2, build 912c1ddf8a)
But it would be ideal to be compatible with containerd too.

The issue is the heuristic here is broken because newer oci layers do gzip small layers, so they are skipped because they don't fill the buffer. Commenting out that check means I can load gcr.io/distroless/nodejs20-debian12:latest which I couldn't before.

I hacked around it, pushed my changes here: https://github.com/froody/dive/tree/crane

quite a significant change, basically uses crane as a dest for docker to "push" to, much faster downloads, and now we have the manifest/config ahead of time to decide on the file format

Wow, thank you for your work! Can you make a PR?
