Prisma

```datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}```
is it possible to read url from file?
Something like
```url = file("/path/to/file/")```

I'm using docker secrets, so all I have is a path to the secret

You can do this:
```
dotenv -e path/to/.env — prisma generate
```

Also, what is the “path to secret”? Is it the file path?

yes. when you use docker secrets it mounts a file with a secret into your container. So if you open /run/secrets/database_url you will see nothing but a url connection string
