Deploy FastAPI to UpCloud

Steps

1. 1

   Create a UpCloud API token

   In your UpCloud account, open Account → Permissions → API access and create a new API user with read-write access. 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 UpCloud server

   In Railyard, open Servers, then Add a server, then Create on your cloud, and pick UpCloud, a region and a size. Railyard preselects 1xCPU-2GB (1 vCPU, 2 GB of memory). It creates the server in your UpCloud 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.
