Docmost on Ubuntu 24.04 LTS

Docmost on Ubuntu 24.04 LTS

Docmost is an open source collaborative wiki and documentation platform, a self hosted alternative to Confluence and Notion. It organises knowledge into workspaces, spaces and nested pages, edited in a rich real time collaborative editor with comments, permissions, labels and full text search, all through a modern web interface.

What is included

• Docmost v0.95.0, the AGPL 3.0 self hosted Community core, pinned by image digest
• A bundled PostgreSQL and Redis, pinned by digest and reachable only inside a private container network
• Docker Engine with Docmost on the loopback interface behind nginx on port 80
• A unique application secret, database password, cache password and a pre seeded workspace owner administrator generated per VM on first boot
• A clean, empty workspace on first boot with no default account and no shipped secret
• 24/7 cloudimg support

Secure by default

A fresh Docmost instance has no workspace, and the first account created owns it, which is a risk on a public server. This image closes it: on first boot, before the port is reachable, a unique workspace owner administrator is created with a per VM password, so the workspace is already claimed. After that, setup is permanently blocked and self hosted Docmost has no open sign up, so new members join by invitation only. PostgreSQL and Redis are never exposed on a host port.

Licensing

Docmost is free and open source under the GNU Affero General Public License v3.0, shipped unmodified. There is no per seat fee. The cloudimg charge of 0.04 US dollars per vCPU hour covers packaging, security patching, image maintenance and 24/7 support. Recommended size: Standard_B2s. This image is produced by cloudimg and is not affiliated with, endorsed by, or sponsored by Docmost.

Before you start

Docmost is served over plain HTTP on port 80. Front it with TLS and your own domain and restrict the network security group before production. Prerequisites: an Azure subscription, a VNet and an SSH key. Inbound rules: port 22 for SSH and port 80 for the web interface.
