11/29/2022, 3:49 PMI am not able to figure out what should I pass as CMD in the suggested dockerfile
Copy code
ENTRYPOINT [ "/usr/local/bin/python", "-m", "awslambdaric" ]
CMD [ "app.handler" ]refined-addition-53644
11/29/2022, 3:52 PMIn the earlier thread @enough-analyst-54434 had it working with the AWS provided docker image

Copy code
FROM public.ecr.aws/lambda/python:3.9
COPY project/lambda.zip ${LAMBDA_TASK_ROOT}
ENV PYTHONPATH ${LAMBDA_TASK_ROOT}/lambda.zip
CMD ["__pex__.lambda_example.example_handler"]s

11/29/2022, 3:59 PMwe set
entry_point="awslambdaric"pex_binary😮 1
sparse-lifeguard-95737
11/29/2022, 3:59 PMthen in the Dockerfile we have:
Copy code
CMD ["./pex", "path.to.entrypoint" ]r

11/29/2022, 4:00 PMI suppose you package awslambdaric inside the PEX itself?

11/29/2022, 4:00 PMyup! we have to set an explicit dependency on it too
sparse-lifeguard-95737
11/29/2022, 4:00 PMfor example:
Copy code
pex_binary(
name="bin",
dependencies=["//3rdparty/pants-only#awslambdaric", ":sources"],
entry_point="awslambdaric",
)🙌 1
r

11/29/2022, 4:02 PMAh you have to set explicit dependencies on your sources too. Do your sources have explicit 1st party dependencies?
s
sparse-lifeguard-95737
11/29/2022, 4:03 PMno, all the dependencies are inferred within the sources themselves
sparse-lifeguard-95737
11/29/2022, 4:03 PMjust have to help the pex_binary figure things out in this case since the entry-point isn’t in the 1st-party code

11/29/2022, 4:03 PMah ok. That’s helpful

11/29/2022, 4:04 PMyes that’s where I was bit unsure

11/29/2022, 4:38 PMWhat pants/pex version are you using?
I am getting error that
./pex Copy code

11/29/2022, 4:41 PMwait is this the pex that is built? Should be ><

11/29/2022, 4:46 PMyes, just realized!! Thank you

11/29/2022, 5:23 PMSo what kind of permissions (if any) you had to provide to run this pex @sparse-lifeguard-95737? I am getting permission denied error
