pip install as a service

A server that performs pip install and returns a zip file containing the installed Python packages (site-packages).

Building and Running with Docker

Build the Docker image:

docker build . -t pip-install

Run the container:

docker run -p 8080:8080 pip-install

Deploying to Google Cloud Run and proxying locally

Deploy:

gcloud run deploy pip-install \
  --source . \
  --cpu 8 \
  --memory 32Gi \
  --no-allow-unauthenticated \
  --region europe-west1

Expose the service locally using Cloud Run's local proxy:

gcloud run services proxy pip-install \
  --region europe-west1 \
  --port 8080

Usage

You can now send a POST request to /install using either a JSON body or by uploading files using multipart/form-data.

Using local files (recommended)

curl -X POST http://localhost:8080/install \
  -F "requirements.txt=@example/requirements.txt" \
  --output python_packages.zip

The constraints.txt field is optional.

Using JSON body

curl -X POST http://localhost:8080/install \
  -H "Content-Type: application/json" \
  -d '{
    "requirements.txt": "flask==2.2.5\nrequests==2.31.0"
  }' \
  --output python_packages.zip

The server will:

1. Create a temporary directory
2. Write the requirements files
3. Run pip install (with constraints if provided)
4. Zip the resulting site-packages directory
5. Stream the zip file back in the response
