Mattermost on Ubuntu 24.04 LTS by cloudimg

## Mattermost on Ubuntu 24.04 LTS

Mattermost Team Edition is an open-source, self-hosted collaboration platform for secure team messaging — organized channels, direct and group messages, file sharing, search, and integrations — giving you full control of your data as a private alternative to hosted chat services. This image is built and maintained by cloudimg on a hardened, fully patched Ubuntu 24.04 LTS base.

### What's included

• Mattermost Team Edition (server) backed by a local PostgreSQL database, managed by systemd
• The Mattermost web UI on port 80 (nginx reverse proxy with WebSocket support)
• A system-administrator account seeded with a unique password on first boot (no shared default, no open sign-up)
• Message and file data stored on a dedicated managed data disk
• Automatic security updates enabled

### Getting started

Retrieve the generated admin credentials with `sudo cat /root/mattermost-credentials.txt`, then sign in at the VM's public IP to create teams and channels and invite users. The deployment guide on cloudimg.co.uk covers configuration, SMTP, and integrations.
