Docker-Compose/WordPress卷挂载权限错误

Question

我的docker-compose.yml

wordpress:
  image: wordpress
  links:
    - wordpress_db:mysql
  ports:
    - 8080:80
  volumes:
    - /tmp/html/:/var/www/html
wordpress_db:
  image: mysql:5.6.29
  environment:
    MYSQL_ROOT_PASSWORD: password
phpmyadmin:
  image: corbinu/docker-phpmyadmin
  links:
    - wordpress_db:mysql
  ports:
    - 8181:80
  environment:
    MYSQL_USERNAME: root
    MYSQL_ROOT_PASSWORD: password

当我执行

sudo /usr/local/bin/docker-compose up

时，我会得到很多这样的信息

有什么想法吗？

我将 /tmp/html 的权限设置为了 777。

Answer 1

关于权限被拒绝的问题，可能与以下内容有关：

• 主机（在 Windows 或 ac 上，只有 C:\Users 或 /Users 被 Linux VirtualHost 挂载）
  这将使 /tmp 为空，导致 /var/www/html 为空。
• Linux 安全策略（请参见 docker-library/wordpress 问题 132）如果您直接在 Linux 主机上。

问题在于 setenforce 0 在 Fedora 和 CentOS 上的工作方式不同

是的，问题出在SELinux上，一旦切换到宽容模式就可以工作了。 - DmitrySemenov
