Is there a way to read from Docker secret files?

Hi all,

Is there a way to read PORKBUN_API_KEY and PORKBUN_API_SECRET_KEY from secret files created by Docker?

Yes, I do it like this:

docker-compose.yml

services:
  caddy:
    container_name: caddy
    build:
      context: ./
      target: caddy
    ports:
      - "80:80"
      - "443:443"
    environment:
      - PORKBUN_API_KEY=${PORKBUN_API_KEY}
      - PORKBUN_API_SECRET_KEY=${PORKBUN_API_SECRET_KEY}

.env file

PORKBUN_API_KEY="yourKeyHere"
PORKBUN_API_SECRET_KEY="youSecretKeyHere"

I place the .env file next to the compose file. It reads the env and uses the values from .env file within the compose file.
