Outline Knowledgebase Wiki is an open-source wiki tool designed for teams to document their knowledge efficiently. In this guide, we will walk through the steps to install Outline using Docker on Ubuntu.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo apt update && sudo apt upgrade

Step 2: Install Docker

If you haven't installed Docker yet, you can do so by running the following commands:

sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce

Step 3: Install Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. Install it using:

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Step 4: Create a Directory for Outline

Create a directory to hold the Outline files:

mkdir ~/outline
cd ~/outline

Step 5: Create the Docker Compose File

Create a docker-compose.yml file in the Outline directory with the following content:

version: '3'
services:
  outline:
    image: outline/outline
    ports:
      - "80:80"
    environment:
      - DATABASE_URL=mysql://outline:password@mysql/outline
    depends_on:
      - mysql
  mysql:
    image: mysql:5.7
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=outline
      - MYSQL_USER=outline
      - MYSQL_PASSWORD=password
    volumes:
      - mysql_data:/var/lib/mysql

volumes:
  mysql_data:

Step 6: Start Outline

Run the following command to start Outline using Docker Compose:

sudo docker-compose up -d

Step 7: Access the Outline Web Interface

Once the containers are running, you can access the Outline web interface by navigating to:

http://your_server_ip

Follow the on-screen instructions to complete the setup process.

Step 8: Configure Nginx (Optional)

If you want to run Outline behind a reverse proxy, you can set up Nginx. Install Nginx:

sudo apt install nginx

Configure Nginx to proxy requests to your Outline instance:

server {
        listen 80;
        server_name your_domain_or_ip;

        location / {
            proxy_pass http://localhost:80;
            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;
        }
    }

Then restart Nginx:

sudo systemctl restart nginx
