Disclaimer

This issue is merely for reference purposes. It's not necessarily intended to be used as triaging for fixing.

Reason: This might be a difficult edge case and I don't have a from-scratch-like clean environment to make sure the steps will lead to a failure.

Description:

Docker build fails when triggered by AWS' sam build on Mac M1 with target amd64 (cross-plattform).

Error: Build Failed Error: NotFound: content digest sha256:[...]: not found

Notes:

The build succeeds if it's directly invoked by docker build.
The build succeeds if the target is arm64
It's not clear whether this is a sam problem or a docker problem.

Workaround stated at the bottom.

Steps to reproduce:

Configuration
- AWS SAM version: version 1.125.0
- Host: Mac M1
- Docker 4.34.3 or any other version until 4.29
- Target platform: amd64
- buildkit: activated

Command to run

export DOCKER_HOST=unix://"$HOME/.docker/run/docker.sock"
sam build --config-env dev

Note:

For the DOCKER_HOST setting you can also use this more cryptic command, which leads to the same result

Observed result:

Error output: Build Failed Error: NotFound: content digest sha256:[...]: not found

I can't reproduce the debug output, because I already workaround-ed the problem. 🙏

Expected result:

Build should succeed.
