Deploy FastAPI to Scaleway

Steps

1. 1

   Create a Scaleway API token

   In the Scaleway console, open IAM → API keys and generate a new API key. Railyard needs the access key and secret key, plus your project ID. Paste it into Railyard and tick Save it to the team, so it's reused for every server after this one.

2. 2

   Add a Scaleway server

   In Railyard, open Servers, then Add a server, then Create on your cloud, and pick Scaleway, a region and a size. Railyard preselects DEV1-S (1 vCPU, 2 GB of memory). It creates the server in your Scaleway account and finishes setup in about two minutes.

3. 3

   Deploy your FastAPI repository

   Paste the GitHub link. Railyard reads the repository, detects FastAPI and fills in the build, the port, the release command, workers and Postgres.

4. 4

   Go live on HTTPS

   Railyard builds your app, runs the release command, health-checks the new version and moves traffic only when it answers. Add your domain and the certificate is issued and renewed for you.

What Railyard sets up for FastAPI

• Detected from requirements.txt or pyproject.toml.
• uvicorn serves main:app on $PORT. Point it at your own module if it lives elsewhere.
• psycopg, asyncpg or SQLAlchemy becomes Postgres, with DATABASE_URL injected.
• Set alembic upgrade head as the release command to migrate on every release.
• Any Procfile process becomes a worker you can scale on its own.
