Docker-compose 正在使用 1001:1001 USER:GROUP 安裝卷

Question

在遠程 VPS 上，由於這個 docker-compose，我正在安裝卷：

version:  '3.3'

services:
  webapp:
    build:
      context: ./docker/webapp/
    volumes:
      - '${RELEASES_DIRECTORY}:/var/apps/site.org/releases'
      - '${REPO_DIRECTORY}:/var/apps/site.org/repo'
      - '${SHARED_DIRECTORY}:/var/apps/site.org/shared'
      - './docker/webapp/over.php.ini:/usr/local/etc/php/conf.d/over.php.ini'
    environment:
      - APP_ENV=prod
      - APP_DEBUG=0
      - APP_DATABASE_URL=mysql://${MYSQL_USER}:${MYSQL_PASSWORD}@${MYSQL_HOST}/${MYSQL_DATABASE}
      - MYSQL_SERVER_VERSION=${MYSQL_SERVER_VERSION}
      - MAILER_DSN=sendgrid+api://${SENDGRID_API_KEY}@default
    working_dir: /var/apps/site.org
    command: php-fpm

這是相對的Dockerfile：

FROM php:7.4-fpm-alpine

# OS DEPENDENCIES

#Creation APP Directory
RUN mkdir -p /var/apps
RUN mkdir -p /var/apps/site

# COMPOSER INSTALLATION
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

# EXORT COMPOSER GLOBAL PATH
RUN echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bashrc
RUN source ~/.bashrc

# INSTALL NODE & NPM
RUN apk add --update nodejs npm
RUN npm config set production
RUN export NODE_ENV=production

On my local machine, when I go inside the docker throung docker exec , every mapped directories are root:root but on my remote host (VPS), they are 1001:1001 and I donèt get where does it can come from?

我嘗試重新安裝 docker 和 docker-compose 但我的行為相同。 VPS 運行

• Unbuntu 18.04
• Docker 版本 19.03.8，構建 afacb8b7f0
• docker-compose 版本 1.25.5，構建 8a1c60f6

當您將主機文件綁定到 docker 容器（綁定掛載）時，文件的權限不會更改。

您的 VPS 可能擁有 uid 為 1001 的用戶擁有的那些文件，而您系統上的相同文件由 root 擁有。
