Example snippet from docker-compose file:

services:
  xyz:
    image: docker.io/xyz/xyz:latest
    restart: always
    environment:
      - DATABASE_USER=xyz
      - DATABASE_PASS=xxxx #insert your secure database password!
      - DATABASE_NAME=xyz
      - DATABASE_HOST=database
    ports:
      - 4000:4000
    volumes:
      - ./import:/opt/app/import
    cap_drop:
      - all

Result:

[xyz@container-1 ~]$ podlet -i compose docker-compose.yml

Thanks for submitting an issue! This has actually already been fixed in the podman-v4.6.0 branch with commit fbb2c0ce43369661a141cdca658a0fbcd567c966, which will be released soon.
