Limitations

• Some unexpected issues may happen after you scale out your site to multiple instances, if you deploy a WordPress site on Azure with this docker image and use the MariaDB built in this docker image as the database.
• The phpMyAdmin built in this docker image is available only when you use the MariaDB built in this docker image as the database.
• Must include App Setting WEBSITES_ENABLE_APP_SERVICE_STORAGE = true since we need files to be persisted. Do not use local storage for WordPress. You can use local storage for transient data or cached data say /tmp folder.
