      }
      
      env {
        POSTGRES_DB = "mydb"
        POSTGRES_USER = "user"
        POSTGRES_PASSWORD = "password"
      }
    }
  }

Here’s mine if it helps.

In dependents, you simply connect via:

DB_POSTGRESDB_HOST="postgres.virtual.consul"

Make sure you’ve enabled the intentions.

But looks like you might have an ACL/workload-identity issue.
