Docker Application with Managed Database

Posted on January 10, 2021

I have a Python (FastAPI) application running on the app platform within a docker container which I’d like to connect to a managed database. At the moment, I’m only using a dev database.

When I deploy my application, the message which pops up is as follows:

asyncpg.exceptions.InvalidAuthorizationSpecificationError: no pg_hba.conf entry for host "167.99.147.79", user "db", database "db", SSL off

I’m using sqlalchemy to make the connection, but it appears as though I’m making the conscious effort not to use SSL.

Default connection options try SSL first; when I require it, it still returns this message.

Any leads? I imagine the cause is that the server may not be set up for SSL from the get-go, but I’m stumped on proving this to myself.

Hi there @wjziv,

You would need to pass the CA certificate to your application as an environment variable.

You can refer to the CA_CERT variable which holds the CA certificate for the managed databases.

For more information on how to use the environment variables on the App platform, I could suggest taking a look at the official documentation here:

https://www.digitalocean.com/docs/app-platform/how-to/use-environment-variables/

Hope that this helps.

Regards, Bobby
