PUID and GUID ignored by docker container

Following advice from https://wiki.omv-extras.org/doku.php?id=omv7:docker_in_omv, I would like to set a dedicated PUID and PGID per docker service.

Hence, I edited the `environment` section of my docker compose file with the following lines:
```

environment:

PUID: ${ICLOUDPD_ID}

PGID: ${ICLOUDPD_ID}

```

However, the files created by the container still belong to `root:root`.
I have another container for which this works however. What do I miss ?

The compose file which gives me trouble is the following
```

x-icloudpd: &icloudpd_base

image: icloudpd/icloudpd:latest

environment:

TZ: ${TZ}

PUID: ${ICLOUDPD_ID}

PGID: ${ICLOUDPD_ID}

volumes:

- ${ICLOUD_STORAGE_FOLDER}:/data

- ./pyicloud:/pyicloud

stdin_open: true

tty: true

restart: "no"

services:

icloudpd-personal:

<<: *icloudpd_base

command: 'icloudpd --username "xxxhiddenxxx" --library "PrimarySync" ${ICLOUDPD_ARGUMENTS}'
```

Thanks !

What is the best approach to have docker services write files with a different ownership than root:root ?

:o thanks ! I feel sorry you had to go through the doc of icloudpd. Thanks again 🙏

edit: I'm actually not using the docker compose from boredazfcuk, so the suggestion doesn't apply to me, but I get it: There's not a universal way to do.
