Docker build hangs with uv sync

[jules-ch]

Docker build hangs with this configuration.
It's working outside of docker.

uv version: uv 0.3.1 (be17d132a 2024-08-21)

Tested on both Linux Ubuntu and Windows.

Probably related to network calls.

FROM python:3.11-slim
ENV RUST_LOG=TRACE
RUN pip install uv

COPY ./pyproject.toml ./uv.lock ./
RUN uv venv
RUN uv sync

pyproject.toml :

[project]
name = "test"
version = "0.1.0"
description = ""
readme = "README.md"
requires-python = ">=3.11"
dependencies = [
  "fastapi>=0.112.1",
  "pyjwt[crypto]>=2.9.0",
  "polars>=1.5.0",
  "pyarrow>=17.0.0",
  "numpy>=2.1.0",
  "pydantic>=2.8.2",
  "pydantic-settings>=2.4.0",
  "uvicorn[standard]>=0.30.6",
  "arq>=0.26.0",
  "psycopg[binary]>=3.2.1",
  "fastjsonschema>=2.20.0",
  "structlog>=24.4.0",
  "httpx>=0.27.0",
  "xarray>=2024.7.0",
  "aiocache[redis]>=0.12.2",

]

Hi! Is this a duplicate of #6443?

[jules-ch]

Yeah seems t be related.

Using just pyproject.toml + uv.lock does not seem to work.
When I add my src folder with hatchling

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

[tool.hatch.build.targets.wheel]
packages = ["src"]

It works, still failing with default setuptools

[zanieb]

Unfortunately this is a setuptools bug — and I think we need to default to that to match the specification. Maybe there's something we can do to help avoid hanging here though...

Alright I'm closing thanks for pointing the related issue :)
