Can I produce a pex with the whole content of a resolve? To use as a base image?

Is your resolve generated from a single target generator (eg.

python_requirements

or

poetry_requirements

)? It should work if you just do

pex_binary(dependencies=["//3rdparty/python:poetry"])

If you have a bunch of disparate requirements in various targets that are all pulled together into one resolve, this would be a bit more complicated
