Subject: EFAULT (Bad address) error during file extraction in Container Station 3

English Container & Virtualization

Your YAML file has some issues:

  1. You cannot use network = host because WordPress uses TCP port 80, which conflicts with the QTS system. We recommend using a different port or using bridging to obtain a different IP address.
  3. Your WordPress should not use 127.0.0.1 when connecting to MariaDB; you can use their Docker names.
  5. Since files need to be uncompressed to the docker volume space , you can add :z to the end of volumes.

You can refer to my YAML file below, and then you can access your WordPress via http://nas_ip:12345
