question: how to install pip packages with this minimal image?

[rtsui-harmonicinc]

I tried using the following, it shows that pip is unavailable

 > [linux/arm64 3/5] RUN ["python3", "-m", "pip", "install", "--no-cache-dir", "-r", "requirements.txt"]:
0.067 /usr/bin/python3: No module named pip
------
Error: unknown: "failed to solve: process "python3 -m pip install --no-cache-dir -r requirements.txt" did not complete successfully: exit code: 1"

Image used: docker.io/ubuntu/python:3.10-22.04_stable

thank you

 > [linux/arm64 3/6] RUN ["python3", "-m", "ensurepip"]:
0.073 /usr/bin/python3: No module named ensurepip

ensurepip not available as well

thanks for the question @rtsui-harmonicinc

This image is very minimal by design. There are no pkg managers inside, so in order to add other pkgs to it, I suggest you use some sort of multi-stage build, where you first stage the desired packages/chisel slices (e.g. chisel cut --root /staging python3-pip_bins) and then merge that on top of docker.io/ubuntu/python:3.10-22.04_stable

NOTE: for the time being, the co-existence of Chisel manifests needs to be handled during the merge, as Chisel is still gaining the ability to cut packages on top of existing chiseled filesystems
