Does App Platform build live in trusted sources?

I’m setting up a ruby on rails application and the build step is timing out trying to get a DB connection even though I’ve setup the app as a trusted source:

I have verified I can connect to the database from my home when adding my home IP to the trusted sources:

Hi there,

Indeed you are correct. During the build process your app would not have access to the Managed Database cluster in case that you have the trusted sources enabled. What I would suggest is that if you have a migrations step, you could move that step from the build process to the deploy process.

The benefit of doing this is that, if your build is successful and the changes to the database are executed, but the deployment fails, then you might end up with the new database schema but with your old codebase which might not be backwards compatible.

Let me know how it goes!
