To deploy a FastAPI application in Ploomber Cloud you need:


You need to provide a Dockerfile, you can use this template to get started. The template contains the minimal steps needed for a deployment but you need to modify so it installs any required dependencies and copies your code into the Docker image.

FROM python:3.11

# assumes contains your fastapi app
# install dependencies
RUN pip install fastapi uvicorn

# this configuration is needed for your app to work, do not change it
ENTRYPOINT ["uvicorn", "app:app", "--host=", "--port=80"]

Testing locally#

To test your app, you can use docker locally:

# build the docker image
docker build . -t fastapi

# run it
docker run -p 5000:80 fastapi

Now, open to see your app.


Once you have all your files, create a zip file.

To deploy a FastAPI app from the deployment menu, follow these instructions:


To ensure your app doesn’t break on re-deployments, pin your dependencies.
