PR to fix the breaking docker-py test: #3290 I called it out there, but we'll need to TAL at the dependencies between the engine and docker-py. Docker-py runs integration tests against the engine, and the engine uses docker-py to run tests, so changing it in either place first is a bit annoying. We might need to skip the test in docker-py -> change the engine behavior -> unskip+fix the test in docker-py, and update the engine version it runs against. |

Docker Engine has always returned `126` when starting an exec fails due to a missing binary, but this was due to a bug in the daemon causing the correct exit code to be overwritten in some cases – see: moby/moby#45795 Change tests to expect correct exit code (`127`).

Temporarily skip the exec run failed exit code test in `docker-py` – https://github.com/docker/docker-py/blob/a3652028b1ead708bd9191efb286f909ba6c2a49/tests/integration/models_containers_test.py#L356-L363 We can reenable this after the PR fixing the expected exit code in that test is merged/released/included – docker/docker-py#3290 Signed-off-by: Laura Brehm <[email protected]>

The Docker Engine has always returned
126when starting an exec fails due to a missing binary, but this was due to a bug in the daemon causing the correct exit code to be overwritten in some cases – see: moby/moby#45795Change tests to expect correct exit code (
127).Note: Must take some care to what's the best way to fix this without breaking engine or vice-versa, due to the engine running tests against docker-py and docker-py running tests against the engine. It might be necessary to 1st. skip the test, then fix the engine, then fix/unskip the test.
