Memory: 1 GB RAM minimum (2 GB RAM recommended for optimal caching and database performance).
Storage: 20 GB of SSD storage (scale up based on attachment and file upload requirements).
Domain Name: A registered domain or subdomain (e.g., wiki.yourcompany.com) pointed to your VPS IP address.

Software Dependencies

Docmost leverages modern containerization to simplify dependencies. The primary components include:

Docmost Core App: The main application binary compiled from Go.
PostgreSQL: The primary relational database used to store pages, user data, and configurations.
Redis: An in-memory data structure store used for caching, session management, and handling real-time WebSocket connections.
Docker & Docker Compose: The container orchestration tools used to deploy and manage these services effortlessly.

Step-by-Step Deployment Guide via Docker Compose

Utilizing Docker Compose is the most efficient and maintainable method for deploying Docmost on a VPS. Follow these systematic steps to transition from a clean server to a fully operational knowledge base platform.

Step 1: Preparing the Server and Installing Docker

Connect to your VPS via SSH and update the system packages to their latest versions to ensure security patches are applied:

sudo apt update && sudo apt upgrade -y

Next, install Docker and Docker Compose if they are not already present on your system:

sudo apt install docker.io docker-compose -y
sudo systemctl enable --now docker

Step 2: Configuring the Deployment Environment

Create a dedicated directory for your Docmost deployment to keep your server configuration organized:

mkdir -p /opt/docmost && cd /opt/docmost

Within this directory, create a docker-compose.yml file. This file will define the service lifecycle, network configurations, and volume bindings for Docmost, PostgreSQL, and Redis. Below is a production-optimized template:

version: '3.8'

services:
  docmost:
    image: docmost/docmost:latest
    container_name: docmost_app
    depends_on:
      - db
      - redis
    environment:
      - APP_ENV=production
      - APP_URL=[https://wiki.yourcompany.com](https://wiki.yourcompany.com)
      - DB_DRIVER=postgres
      - DB_HOST=db
      - DB_PORT=5432
      - DB_USER=docmost_user
      - DB_PASSWORD=YourSecurePasswordHere
      - DB_NAME=docmost_db
      - REDIS_HOST=redis
      - REDIS_PORT=6339
      - APP_SECRET=A_Long_Random_Secret_Key_For_Sessions
    ports:
      - "3000:3000"
    volumes:
      - docmost_data:/app/data
    restart: always

  db:
    image: postgres:15-alpine
    container_name: docmost_db
    environment:
      - POSTGRES_USER=docmost_user
      - POSTGRES_PASSWORD=YourSecurePasswordHere
      - POSTGRES_DB=docmost_db
    volumes:
      - pg_data:/var/lib/postgresql/data
    restart: always

  redis:
    image: redis:7-alpine
    container_name: docmost_redis
    command: redis-server --port 6339
    volumes:
      - redis_data:/data
    restart: always

volumes:
  docmost_data:
  pg_data:
  redis_data:

Note: Ensure you replace YourSecurePasswordHere and A_Long_Random_Secret_Key_For_Sessions with complex, unique alphanumeric keys to secure your database and application sessions.

Step 3: Launching the Services

With the configuration file properly populated, execute the following command to download the required container images and initialize the platform in detached mode:

sudo docker-compose up -d

Verify that all containers are running successfully by checking their statuses:

sudo docker-compose ps

Configuring a Reverse Proxy and SSL Certificates

Running an enterprise application over an unencrypted HTTP connection poses severe security vulnerabilities. To safeguard user credentials and proprietary corporate intelligence, you must configure a reverse proxy like Nginx paired with a free TLS certificate from Let's Encrypt.

1. Install Nginx

Install the Nginx web server to handle incoming traffic and route it to your Docker container:

sudo apt install nginx -y

2. Configure Nginx Server Block

Create a configuration file for your Docmost subdomain:

sudo nano /etc/nginx/sites-available/docmost

Insert the following server block configuration, mapping the external HTTP requests to the internal application port:

server {
    listen 80;
    server_name wiki.yourcompany.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded-for;
        proxy_set_header X-Forwarded-Proto $scheme;
        
        # WebSocket support for real-time collaboration
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Enable the site configuration by creating a symbolic link and reload the Nginx service:

sudo ln -s /etc/nginx/sites-available/docmost /etc/nginx/sites-enabled/
sudo systemctl reload nginx

3. Implement Let's Encrypt SSL

Utilize Certbot to completely automate the acquisition and renewal of your SSL certificate:

sudo apt install certbot python3-certbot-nginx -y
sudo certbot --nginx -d wiki.yourcompany.com

Follow the interactive prompts to enable automatic HTTP-to-HTTPS redirection. Once completed, your Docmost installation is securely encrypted.

Post-Installation and Initial Onboarding

With the server infrastructure finalized, open your web browser and navigate to your configured domain (e.g., [https://wiki.yourcompany.com](https://wiki.yourcompany.com)). You will be greeted by the initial setup wizard.

During this stage, you will establish the Global Administrator Account. Provide a secure corporate email address and an enterprise-grade passphrase. As the administrator, you can immediately access the control panel to:

Configure your organization profile and branding.
Invite team members via email or configure external authentication providers if supported.
Set up automated email notifications (SMTP server details) for seamless user onboarding and activity alerts.
Initialize your first organizational Spaces and begin drafting vital documentation.
