Permission problem in startup script
I am trying to implement a Chainlit app that needs to access a Qdrant server, and is managed with UV.  I use qdrant/qdrant as the base model in my dockerfile, then I import UV.  In order to start Qdrant before trying to run my app, I use an entrypoint instead of cmd.When I run the app directly on my desktop, with an already running Qdrant server, it works fine.  When I build and run the dockerfile locally, it runs perfectly.  But when I push the code back to Hugging Face,  Qdrant starts up but the UV command is not visible.Dockerfile:# Trying to put qdrant into same container as chainlit application

# Start with qdrant image

# Need curl and ca-certificates

    && rm -rf /var/lib/apt/lists/*

This may be due to a change in theuvspecifications. It seems that specifying a version may fix the problem.github.com/astral-sh/uvUV not found; Docker install fails with latest install and `v0.5.0`opened04:00PM - 08 Nov 24 UTCclosed04:15PM - 08 Nov 24 UTCdwillhelmHi, love your work. 

My docker builds are failing this morning due to a `uv`…installation issue. I'm following [this example](https://docs.astral.sh/uv/guides/integration/docker/#installing-uv:~:text=uvx%20/bin/-,Or%2C%20with%20the%20installer%3A,-Dockerfile) from the docs. I was able to fix it by pinning to a older version, but figured it was worthwhile to create the issue. 

In my dockerfile, using
```dockerfile
ADD https://astral.sh/uv/install.sh /uv-installer.sh
```
or 
```dockerfile 
ADD https://astral.sh/uv/0.5.0/install.sh /uv-installer.sh
```

Results in a 
```console 
RUN uv sync --frozen --no-cache

/bin/sh: 1: uv: not found 
```

Running with an older version, however, does not fail. For example 
```dockerfile 
ADD https://astral.sh/uv/0.4.17/install.sh /uv-installer.sh
```

Here's part of my `Dockerfile` just in case
```dockerfile
# this is my dockerfile
FROM python:3.11-slim

# The installer requires curl (and certificates) to download the release archive
RUN apt-get update && apt-get install -y --no-install-recommends curl ca-certificates

# Download the latest installer
ADD https://astral.sh/uv/0.4.17/install.sh /uv-installer.sh # <-- pinning version fixed it for me! 

# Run the installer then remove it
RUN sh /uv-installer.sh && rm /uv-installer.sh

# Ensure the installed binary is on the `PATH`
ENV PATH="/root/.cargo/bin/:$PATH"

WORKDIR /backend
...
...

```


I resolved my issue by pinning the version, but figured others might come across the issue. Thanks

Thanks.  UV is available in the Dockerfile because the RUN uv sync —frozen command is successfully executed.

I changed some things and got interesting information.  In the Dockerfile:ENV PATH="/root/.local/bin:$PATH"and the script:#!/bin/bash
echo "Current directory: $(pwd)"
echo "Current path: $PATH"

directory="../root/.local/bin"
if [ -d "$directory" ];
then
    echo "Directory exists: $directory"
    echo "Files in $directory:"
    find "$directory" -type f
else
    echo "Directory does not exist: $directory"
fiWhen I create a Docker container and run it on my desktop using Desktop Docker, I see the following:Current directory: /app
2025-01-08 11:15:05 Current path: /root/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
2025-01-08 11:15:05 Directory exists: ../root/.local/bin
2025-01-08 11:15:05 Files in ../root/.local/bin:

2025-01-08 11:15:05 ../root/.local/bin/env
2025-01-08 11:15:05 ../root/.local/bin/uvWhen I push to Hugging Face I see this:Current directory: /app

Directory does not exist: ../root/.local/bin

There are various unique restrictions on Docker Spaces for HF, but to put it briefly, you should assume that, in principle, you can only access the app/ directory and below after starting up.For example, if you need to modify the Python system directory during installation, you’ll need to use a rather roundabout method to get it to work. Or you won’t be able to do it at all.When the things we’ve brought over from github don’t work smoothly, it’s usually because of the above problem or because the model file is too large and it’s caught by the recent Spaces git restriction (1GB).

So in my Dockerfile, having installed UV (which later executes in the Dockerfile stage) in root/.local/bin, I could copy the uv components into the /app directory, and then hit uv in the app directory?
2025-01-10T02:18:33Z
Maybe. I don’t know if uv will work in that state, but if it doesn’t matter where you put it, then it should be fine. You can also call it from Python using subprocess or system.As long as we don’t touch the system directory or libraries that are implicitly prohibited, we can do most things freely. There are generally fewer restrictions after startup than during startup.
