#18772 Missing transitive dependencies of pex_binary depending on python_dist running inside a docker_image Issue created by idan-at Describe the bug I am using a

docker_image

target to test a CLI.

docker_image(
  name="docker",
  skip_push=True,
  dependencies=[":bin"],
  repository="e2e-tests-image",
  instructions=[
    "FROM python:3.9",
    "COPY cli.tests/bin.pex /bin/cli"
  ]
)

Although I wanted to directly copy the python distribution into the image, I couldn't find a way to do so, so I am using a

pex_binary

that depends on the

python_distribution

.

pex_binary(
  name="bin",
  entry_point="cli.main",
  dependencies=["cli/src:dist"]
)

When I run the generated pex file manually on my machine, it works fine. When I try to run

cli

inside a container (

docker run -it e2e-tests-image bash

), I get the following error (no transitive dependencies found)

Failed to find compatible interpreter on path /usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin.

Examined the following interpreters:
1.) /usr/local/bin/python3.9 CPython==3.9.16
2.)       /usr/bin/python3.9 CPython==3.9.2

No interpreter compatible with the requested constraints was found:
