Unable to build S2I Core base image from source

[micsafi]

While building the S2I Core base image from source, the base image build fails on the tagging phase:

Before running the build, I have installed the coreutils+md2man and updated my path to have the gnuutils to have priority.

Just to add: since the Docker build completes successfully, I can workaround the error by manually tagging the images and pushing them to my private registry. But it would great to understand why the Make build fails on my Mac.

Hi @micsafi

Thank you for flagging this issue.

Please confirm the version of Docker Desktop for Mac you're using.

Last I ran this, it was 3.1.0, and the build worked fine. After upgrading to 3.2.2, I'm able to reproduce your issue.
The latest version is using BuildKit by default which has an issue with some of the paths used by the S2I Core image build.
I have created an issue with the S2I image maintainers for further investigation.

In the meantime, you can revert to the old build process by setting the DOCKER_BUILDKIT variable to 0 for the current terminal, or by updating the Docker daemon configuration file with the following snippet:

{ "features": { "buildkit": false } }

We will add a note to the runbook about this change in behaviour.

My build findings are with Docker Desktop v. 3.2.1 on MacOS.

I am also happy to confirm that setting DOCKER_BUILDKIT=0 fixes the build issue. I think this is more than sufficient workaround for now! Just add it to the Runbook instructions.
