Question

my docker-compose.yml

  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

any ideas?

I set 777 to /tmp/html

Answer 1

Regarding the permission denied part, this could be linked to:

• the host (on Windows or ac, only C:\\Users or /Users is mounted by the Linux VirtualHost)
  That would make /tmp empty, resulting in an empty /var/www/html .
• the Linux sec policy (see docker-library/wordpress issue 132 ) if you are directly on a Linux host.

The problem is that setenforce 0 works differently on Fedora and CentOS
