 You can use the `support/scripts/systemd-container-service-file-generate` to easily create a `systemd` service file for this project:

 - When this script is run, it will generate `systemd` service file called `~/.config/systemd/user/phoenix-todo-list.service` (unless the `--dry-run` flag is set)
 - Other flags:
   - `--dry-run` - Display the service file in the terminal instead of writing to a file.
     - No permanent changes are made when this flag is used.
     - The output of a `--dry-run` is identical to the real service file, and can be piped as needed.

   - `--postgres` - Run a Postgres container as part of the service.
