Part of my docker compose file

version: "3.1"
services:
  codecontainer:
    container_name: codecontainer
    build: .
    user: www-data
    volumes:
      - codecontainerdata:/var/www/html
  php:
    container_name: php
    restart: always
    build:
      context: ./build/php
      args:

  codecontainerdata:
  • :white_check_mark: Both Dockerfiles creating same www-data user and group
  • :white_check_mark: Dockerfile in Codecontainer copy files into /var/www/html
  • :white_check_mark: all files in dir /var/www/html inside codecontainer are getting chown www-data:www-data
  • :white_check_mark: docker-compose up

Problem:

  • :x: docker exec -ti -u www-data php ls -la /var/www/html => all files are owned root:root
  • :x: docker exec -ti php chown -R www-data:www-data /var/www
    • … chown: /var/www/html/README.md: Operation not permitted …

If you need to mount volumes, we would recommend using the machine executor. This is documented here: https://circleci.com/docs/2.0/executor-types/#docker-benefits-and-limitations and https://circleci.com/docs/2.0/executor-types/#using-machine
