我可以像这样执行docker run命令…

docker run --rm  --user $(id -u):$(id -g) -e MYDATA=/some/path/to/data -e USER=$USER -p 8883-8887:8883-8887 ...

但是，在Docker Compose中，当我写出以下内容时...

version: '3.7'
services:
  container_name: some-server
  image: some:img
  user: $(id -u):$(id -g) 
  ...

...它不工作。
我知道我要求docker-compose up执行子shell命令替换，它不能。
有什么办法可以做到吗？
如果我添加（我的用户有1000个ID）

php:
    user: 1000:1000
    build:
      context: .
      target: app_php

开始我得到

Cannot create cache directory /.composer/cache/repo/flex/, or directory is not writable. Proceeding without cache. See also cache-read-only config if your filesystem is read-only.

我删除容器和重建，但...
