Current Behavior

Adding pymilvus to requirements and then trying to build the docker image fails because of pyarrow.
Error:

Expected Behavior

SDK install should work

Steps To Reproduce

1. add a requirements.txt with pymilvus==2.4.3
2. run `docker compose buid`
3. build fails because of error

@onel It seems it failed when compiling PyArrow. But pymilvus has removed PyArrow as the dependencies in 2.4.3 milvus-io/pymilvus#2087

Can you provide more information on how to reproducing this problem?

Sure thing. This is how I recreated it.

In a folder add these 2 files:
Dockerfile

# base image
FROM python:3.12-alpine

# setup environment variable
ENV DockerHOME=/app/

# set work directory
RUN mkdir -p $DockerHOME

# where your code lives
WORKDIR $DockerHOME

RUN pip install --no-cache --upgrade pip setuptools

# copy whole project to your docker home directory. 
COPY . $DockerHOME

# run this command to install all dependencies
RUN pip install -r requirements.txt

requirements.txt

pymilvus

and run docker build .

In this case I tried with python:3.12-alpine but I get the same result.

I am running
Ubuntu 20.04
Docker version 26.1.4

@onel THX for the scripts. The download of PyMilvus falls back to 2.4.1 because Milvus-lite donesn't support Apline Linux. And we intergrated Milvus-lite into pymilvus in 2.4.2. So that's why your codes raises errors about PyArrow. And PyArrow can't be compiled on Apline Linux too.

Please use python:3.12-slim for base. It works perfectly from my test.

Thanks for the details. Should this be mentioned somewhere in the docs?
I think alpine is the most used image for python development, it should be specified that -slim is recommended.

I can make a PR is you point to the right file
