title: Export current user id in makefile for docker-compose
body: <p>I trying to pass the current user id into <code>docker-compose.yml</code></p>
  
  <p>How it looks in <code>docker-compose.yml</code></p>
  
  <pre><code>version: '3.4'
  
  services:
      app:
          build:
              context: ./
              target: "php-${APP_ENV}"
          user: "${CURRENT_UID}"
  </code></pre>
  
  <p>Instead of <code>CURRENT_UID=$(id -u):$(id -g) docker-compose up -d</code> I've wrote makefile</p>
  
  <pre><code>#!/usr/bin/make
  
  SHELL = /bin/sh
  
  up: 
      export CURRENT_UID=$(id -u):$(id -g)
      docker-compose up -d
  </code></pre>
  
  <p>But <code>CURRENT_UID</code> still empty when I run <code>make up</code></p>
  
  <p>Is there a possible export uid in makefile?</p>
