Running fastapi app using uvicorn on ubuntu server - gunicorn

Question

I am dealing with the project deposition made on FastAPI to a remote ubuntu server. I'll try to run the project from terminal (using SSH connection) by the command
gunicorn -k uvicorn.workers.UvicornWorker main:app
The output is
gunicorn -k uvicorn.workers.UvicornWorker main:app
[2020-07-14 15:24:28 +0000] [23102] [INFO] Starting gunicorn 20.0.4
[2020-07-14 15:24:28 +0000] [23102] [INFO] Listening at: http://127.0.0.1:8000 (23102)
[2020-07-14 15:24:28 +0000] [23102] [INFO] Using worker: uvicorn.workers.UvicornWorker

[2020-07-14 15:24:28 +0000] [23104] [INFO] Application startup complete.
But I need the project to be available at the IP address of the server. If I try smth like
uvicorn main:app --host 66.226.247.55 --port 8000
I get
INFO: Started server process [23308]
INFO: Waiting for application startup.
INFO: Connected to database postgresql://recognition:********#localhost:5432/reco
INFO: Application startup complete.
ERROR: [Errno 99] error while attempting to bind on address ('66.226.247.55', 8000): cannot assign requested address
INFO: Waiting for application shutdown.
INFO: Disconnected from database postgresql://recognition:********#localhost:5432/reco
INFO: Application shutdown complete.
Where 66.226.247.55 - external IP adress from google cloud platform instances
How do I start a project so that it can be accessed via IP?

Answer 1

The --host should be the local address of your GCP server.
uvicorn main:app --host 0.0.0.0 --port 8000
and now access the application by http://66.226.247.55:8000
Note: You should open your 8000 port of GCP server.

Answer 2

If you're using nginx server
create a file in /etc/nginx/sites-enabled/
create file touch fastapi_nginx
copy code into file and adjust accordingly
server{
listen 80;
server_name "your public ip";
location / {
proxy_pass http://127.0.0.1:8000; #localhost
}
}
This should reroute to your public ip

Answer 3

You cannot launch your fast api app on your local to your remote server in GCP.
You must deploy your app to GCP. In other words you need to run that command on a remote server not your localhost.
