InstantCMS on Ubuntu 24.04

InstantCMS, the open source social CMS and community portal engine
InstantCMS is a full open source content management system for building social networks, community portals and content driven websites. It provides user accounts, profiles and groups, multiple content types, blogs, articles and photo galleries, comments, private messaging, moderation and access control, configurable widgets and multi template theming, and the complete administration backend. Site owners launch a members oriented community, publish and moderate content, and extend the portal with its component and widget system. This cloudimg image runs InstantCMS 2.18.2.
Installed and ready. cloudimg builds the image with InstantCMS installed to /var/www/instantcms and the database schema already built, served over HTTPS by Apache 2.4 with mod_php 8.3 and MySQL 8.0 on Ubuntu 24.04, so the portal and admin answer the moment the instance boots, with no setup wizard to complete. Plain HTTP redirects to HTTPS.
Secure by default and asserted, not assumed. The portal holds member data, so the image ships no known credential and no pre authenticated session: the build time admin password is neutralised and the installer's seeded session token is purged, and on each machine's first boot cloudimg rotates a fresh administrator password and a fresh database password, generates a per VM self signed TLS certificate, and sets the portal base URL from the machine's own address. Every value is written to a root only file. Two machines built from this image never share a credential, and a blank, default or guessed admin password is rejected. MySQL binds to loopback only with no shipped root password, and no swap is baked into the disk.
InstantCMS is licensed under the GNU General Public License v2 and is shipped unmodified; it is entirely open source with no paid tier required to reach a working portal, and no subscription, licence key or support contract. The cloudimg charge covers packaging, secure by default hardening and 24/7 support. cloudimg is not affiliated with or endorsed by InstantCMS; the name is used nominatively to identify the software the image contains.
