Guide

Deploy Docmost on your VPS

1. 1

   Order the VPS

   Order a ServOrbit VPS with at least 2 GB of RAM, 4 GB beyond a dozen or so people; the system installed is Ubuntu 24.04. Docmost itself is lightweight: PostgreSQL is what takes up most of the memory budget.

2. 2

   Let the install generate the secrets

   There is nothing for you to craft by hand: the deployment generates the APP_SECRET signing key and the PostgreSQL database password, and fills APP_URL with your instance's public address. That address is the one share links and invitations will follow, so settle your domain before installing if you intend to attach one.

3. 3

   Sign in for the first time

   Open the address immediately after the install: Docmost shows its initial setup screen, where you create the workspace and the owner account — name, e-mail address and password. This first account holds every right, and as long as it does not exist, the first visitor who reaches the instance can claim it: do not put this step off.

4. 4

   What the install deploys

   Three containers start together: docmost/docmost:latest, published on 127.0.0.1:3000, a postgres:16-alpine database and a redis:7-alpine in permanent journal mode (--appendonly yes). Attachments live in the docmost_data volume, the database in docmost_db. Allow about thirty seconds on first boot, the time for the migrations to apply.

5. 5

   Choose your access URL

   Attach a domain to the instance: ServOrbit installs the nginx vhost and the TLS certificate, and Docmost then answers on https://<your-domain>, with no port number. That is the only way to open the wiki to a team. Without a domain there is no public entry point at all: the service listens on the VPS loopback only, and you reach it through an SSH tunnel — ssh -L 3000:127.0.0.1:3000 root@<vps-ip> then http://localhost:3000. Port 3000 is the catalogue default; if it has been reassigned, use the one shown on your app's card in the client area.

6. 6

   Create your workspace

   Name your workspace, then invite your colleagues from Settings, Members section. Pages are organised as a tree in the left-hand column: start with a home page, and let the structure build itself up as the content grows.
