N/A

You want to connect to a psql DB from your local computer?

If so then yes, you just need to use the public url

if same project have two service one db and one py app both can communicate locally ?

this is the structure

AFW-bot wants to talk with postgres

The AFW-bot can connect to the postgres instance. You should use the private DB url for that though.

You can add a env variable to AFW-bot (will be something like ${{Postgres.DATABASE_PRIVATE_URL}}). Then just grab that env variable in your python application to connect to the DB.

ok so private db wont cost me right? only the public one costs?

url i mean

Hey there, little correction needed -
For Postgres databases that are recently deployed you can simply reference DATABASE_URL as it is now the private url

They'll both count towards your usage. It's just better to use a private URL within your service.

oki

Hey, correction again, database to service communication over the private network does not cost anything on egress

But they still have resource usage eh? They're not free

yes of course, but there will be no egress
