Using uv to install packages in the bitnami/deepspeed:0.14.0 Docker image fails with 'uv: command not found'

Question

If I use the following Dockerfile:

FROM python:3.11-bullseye

ENV APP_HOME /app
WORKDIR $APP_HOME

COPY requirements.txt /app

RUN pip install uv && uv pip install --system --no-cache -r requirements.txt

Then the packages in requirements.txt install just fine. But if I change the first line to

FROM bitnami/deepspeed:0.14.0

Then suddenly I get the error

Edit:

I can get it to work if I install the python packages as root:

FROM bitnami/deepspeed:0.14.0

USER root

ENV APP_HOME /app
WORKDIR $APP_HOME

COPY requirements.txt /app

RUN pip install uv && uv pip install --python $(which python) --no-cache -r requirements.txt

But is there a way to use uv to install python packages in the bitnami/deepspeed:0.14.0 Docker image as the deepspeed user?

Answer 1

The installed uv binary is not on PATH, and presumably since it's not a regular Python wrapper script, pip doesn't print out the helpful warning about that.

Refer to the .local-installed uv manually:

RUN pip install uv && ~/.local/bin/uv pip install --system --no-cache -r requirements.txt

Note that --system will likely fail since that image is clearly not running these commands as root.

(Personally, I would probably not use a bitnami/deepspeed image.)
