The Device Mapper driver has been deprecated, and will be removed in Docker Engine v25.0. Following this notice, the OpenPanel project will gradually transition away from utilizing the devicemapper driver.
⚠️ You have the option to manually switch immediately to the overlay2 storage driver. However, please exercise caution as this process involves deleting all existing Docker containers. It is advisable to perform this switch only on fresh, clean servers. It is recommended to execute this action only after installing OpenPanel and before creating any users.
To manually change the driver follow this guide: https://gist.github.com/stefanpejcic/cd2212f766b4637f19f59e29720a0a5c
OpenPanel currently fully supports both the devicemapper and overlay2 drivers. However, as of OpenPanel version 0.2.0, the default storage driver will be overlay2.
