Automatic migrations on managed databases.

Asked by b367bcaf92f84e228b14dd32508c39

Hello.

So I finished setting up my stack, which is a .NET Container running on an app platform with a managed PostgreSQL DB.

I have CI/CD setup with GitHub actions, which pushes an image of my .NET stack to my DO container registry, and the app auto deploys when a new version of it gets pushed.

So far so good.

The thing is my GitHub action also generates a idempotent SQL script which has to be run against my DB before the app gets deployed. The script is stored as an artifact of the build as of now.

I can’t seem to find a way to run the script against my managed DB in DO, I already saw I could add a resource as a job that could be run before the deploy, but it only accepts certain templates and is hard to link with GitHub’s artifacts.

Any idea how I could get around this and could run the script automatically against the DB before the deploy ?

Thanks a lot.

Hi there,

What I personally do is to run my database migrations as part of my run command, that way I make sure that my database schema is up to date right before starting my app.

Here is a quick example:

https://github.com/thedevdojo/wave/blob/main/.do/app.yaml#LL9C72-L9C72

This is a PHP project, but it should be applicable for other frameworks as well.

Let me know how it goes!

Best,

Bobby
