Deploy Flask to DigitalOcean

Steps

1. 1

   Create a DigitalOcean API token

   In the DigitalOcean control panel, open API and generate a personal access token with read and 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 DigitalOcean server

   In Railyard, open Servers, then Add a server, then Create on your cloud, and pick DigitalOcean, a region and a size. Railyard preselects s-1vcpu-2gb (1 vCPU, 2 GB of memory). It creates the server in your DigitalOcean account and installs Docker, Caddy and its agent in about two minutes.

3. 3

   Deploy your Flask repository

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

4. 4

   Go live on HTTPS

   Railyard builds on a separate build server, 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 Flask

• Detected from requirements.txt or pyproject.toml.
• gunicorn serves app:app on $PORT. Point it at your own module if it lives elsewhere.
• Set flask db upgrade or alembic upgrade head as the release command.
• psycopg becomes Postgres, with DATABASE_URL injected.
• RQ is offered as a worker, and any Procfile process becomes one.
