Deploy and Host private-python-registry on Railway

private-python-registry is a ready-to-deploy Railway template that launches your own private Python package index, powered by devpi. It is fully compatible with standard Python tooling — pip, uv, twine, and devpi-client — and ships with a built-in web UI, search, and an on-demand PyPI mirror that caches public dependencies into your own persistent storage.

About Hosting private-python-registry

Hosting private-python-registry on Railway is a one-click affair. The template builds a single container running devpi-server + devpi-web, exposes it on Railway's managed HTTPS domain, and persists every package, user, and login token to a Railway Volume mounted at /data. A persistent server secret is generated on first boot so authentication tokens survive redeploys, and initial admin credentials are seeded from a single DEVPI_ROOT_PASSWORD environment variable. No external database, no reverse proxy, no moving parts — just a Dockerfile, a volume, and a generated domain. Redeploys and restarts are fully idempotent.

Common Use Cases

• Publish and share proprietary Python packages across an engineering team without exposing them on public PyPI
• Host an internal PyPI mirror that caches public dependencies, giving your CI reproducible, fast, and outage-resilient installs
• Distribute pre-release, staging, or customer-specific package builds through isolated per-user indexes with fine-grained access control

Dependencies for private-python-registry Hosting

• A Railway Volume mounted at /data — stores all packages, indexes, users, logins, and the persistent server secret. Without it, every redeploy wipes the registry.
• A public Railway domain generated from the service's Networking settings — required for pip, uv, twine, and devpi-client to reach the index over HTTPS.

Deployment Dependencies

• devpi documentation — upstream project powering the registry
• devpi-server on PyPI
• devpi-web on PyPI — web UI and search
• devpi-client on PyPI — CLI used to create users, indexes, and upload packages
• Railway Volumes documentation
• Railway Public Networking documentation

Implementation Details

After deployment, set DEVPI_ROOT_PASSWORD before the first boot, attach a Volume at /data, and generate a public domain. Then, from any machine with devpi-client installed:

# Point the client at your new registry and log in as root
devpi use https://
devpi login root --password="$DEVPI_ROOT_PASSWORD"

# Create a user and a private index that falls through to PyPI
devpi user -c alice password=s3cret [email protected]
devpi index -c alice/prod bases=root/pypi

# Publish a package with twine
twine upload \
  --repository-url https:///alice/prod/ \
  --username alice --password s3cret \
  dist/*

# Install it back with pip or uv
pip install --index-url https://alice:s3cret@/alice/prod/+simple/ my-private-pkg
uv pip install --index https://alice:s3cret@/alice/prod/+simple/ my-private-pkg

By default the template runs devpi-server with --restrict-modify root, so only the root user can create additional users and indexes. Set DEVPI_RESTRICT_MODIFY="" if you want any authenticated user to create their own indexes instead.
