EGroupware 26 Collaboration Suite on Ubuntu 24.04 LTS by cloudimg

EGroupware is a mature open source collaboration and groupware suite used by businesses, public sector bodies, schools and non profit organisations to run shared calendars, contacts, projects and documents on infrastructure they control. It brings together a group calendar with resource booking, address books, InfoLog for tasks and tickets, a versioned file manager, project manager, time sheet, wiki, bookmarks and news, all behind one sign in with fine grained per group access control. Calendars and contacts synchronise to phones, tablets and desktop clients over CalDAV and CardDAV. This image is built and maintained by cloudimg on a hardened, fully patched Ubuntu 24.04 LTS base, with EGroupware 26 served by Apache and PHP 8.3 and a bundled local MariaDB server, so the appliance is complete and useful on its own.

The installer is pre completed and the setup console is locked away behind a denial, so the suite is ready the moment the instance boots and no customer ever meets an installer. Unique administrator, database and setup console passwords are generated on the first boot of every VM and written to a root only file. The shipped image carries every one of them rotated to discarded random values, so no known or blank credential authenticates. Browse to the VM on port 80, sign in as the admin user, and start scheduling, sharing contacts and tracking work.

This image is address agnostic: EGroupware is configured with a relative web server URL, so it works unchanged on the public IP, on a private address, on your own DNS name, or behind a TLS terminating proxy, with nothing to reconfigure when your address changes. Session cookies are issued host only so sign in behaves correctly however you browse. The bundled MariaDB listens only on the loopback interface (127.0.0.1:3306) and is never exposed to the network. A single dedicated managed data disk carries both the MariaDB database and EGroupware's file store, so your data stays off the operating system disk and rides with the VM. An unauthenticated /healthz endpoint is provided for load balancer probes. The mail app is a client, not a mail server: no SMTP or IMAP daemon ships, and you point it at a mail server you already run whenever you are ready. For production, front port 80 with your own domain and TLS.
