Prisma

Hey, how can i run prisma migrate programmatically when deploying to heroku, right now i have to run the heroku console from the web app, and run `npx prisma migrate`, i'm building everything in docker.

in `package.json`:
``` "scripts": {
        "postinstall": "yarn prisma generate &amp;&amp; yarn prisma migrate deploy --preview-feature ",
   ...
  }```

I'm also deploying to Heroku Nodejs framework with the `heroku/nodejs` buildpack (on the settings page) and the postinstall above works for me.

I think that's what Heroku's release phase is for.

<@UMN2W5LPL> i tried that, but the prisma migrate didn't recognize  the `DATABASE_URL` env variable during postinstall for some reason.

<@U01KCP7U5BJ> That's exaclty what i'm looking for.
