I'm try to build a docker container managed by pants that I have not touch in a few months. The Dockerfile is very simple and I'm able to package the pex file referenced by the Dockerfile with no issues. When packaging the docker image I encounter the error below:

Engine traceback:
  in `package` goal

ProcessExecutionFailure: Process 'Building docker image <http://ghcr.io/unique-image-name:latest|ghcr.io/unique-image-name:latest> +1 additional tag.' failed with exit code 1.
stdout:

ERROR: mkdir /home/runner: operation not supported

The Dockerfile below does not call mkdir. I'm not sure where this error is coming from or how to resolve it. Do I need to grant some permissions to the build system?

FROM python:3.10-bullseye
COPY src.python.service/main.pex /bin
ENTRYPOINT ["/bin/main.pex"]

I do not recognize that error. Based on the

FROM

image you’re using, feels unlikely that it would be from any

ONBUILD

triggers. Can you try to build the image directly using the

docker

cli?

Yeah I think I'll need to change the COPY command. One sec
