wonderfall/nextcloud

New version of my Nextcloud image, still in testing:

• Fetching PHP/nginx from their official images.
• Does not use any privilege at any time, even at startup.
• Much easier to maintain thanks to multi-stages build.
• Includes hardened_malloc, a hardened memory allocator.
• Does not include imagick, samba, etc. by default.

Goals: simple, lean, and secure.

Be aware this image is not ready yet for production use. While it might work, please note a fresh install from the previous image is recommended. If you intend to migrate, please back up your data.
