In this tutorial, we'll explain how to deploy LibreOffice Online with Docker on Ubuntu 22.04 server.
LibreOffice Online (also known as Collabora Online) is a powerful online office suite with collaborative editing capabilities. This guide will walk you through the steps required to deploy Collabora Online on an Ubuntu server.
Prerequisites
- An Ubuntu dedicated server or KVM VPS (20.04 or later).
- Root or sudo access to the server.
- A domain name pointing to your server's IP address.
- Basic knowledge of Linux command line.
Step 1: Update Your System
Before starting, ensure your system is up to date:
sudo apt update
sudo apt upgrade -y
Step 2: Install Docker
Collabora Online runs in a Docker container. Install Docker using the following commands:
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
Install Docker using following command:
sudo apt install docker.io
Check the Docker installation:
sudo systemctl status docker
Step 3: Install Docker Compose
Docker Compose is a tool for defining and running multi-container Docker applications. Install Docker Compose:
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*?(?=")')/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Verify the installation:
docker-compose --version
Step 4: Download and Configure Collabora Online
Create a directory for the Collabora Online Docker configuration:
mkdir ~/collabora
cd ~/collabora
Create a docker-compose.yml file:
nano docker-compose.yml
Add the following configuration to the file:
version: '3.9'
services:
collabora:
image: collabora/code
container_name: collabora
environment:
- domain=your.domain.com # Replace with your actual domain
- username=admin
- password=secret # Replace with a strong password
- extra_params=--o:ssl.enable=false
ports:
- "9980:9980"
restart: always
Save and close the file (Ctrl+O, Enter, Ctrl+X).
Step 5: Start Collabora Online
Start the Collabora Online container:
sudo docker-compose up -d
Check the status of the container:
sudo docker ps
Step 6: Set Up Reverse Proxy with Nginx
To access Collabora Online through your domain, set up an Nginx reverse proxy. Install Nginx:
sudo apt install nginx -y
Create a new Nginx configuration file:
sudo nano /etc/nginx/sites-available/collabora
Add the following configuration, replacing your.domain.com with your actual domain:
server {
listen 80;
server_name your.domain.com;
location / {
proxy_pass http://localhost:9980;
proxy_set_header Host $http_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;
}
}
Enable the configuration:
sudo ln -s /etc/nginx/sites-available/collabora /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx
Step 7: Configure Firewall
We need to configure firewall and add HTTP and HTTPS port.
ufw allow 80/tcp
ufw allow 443/tcp
ufw reload
Step 8: Secure Your Site with Let's Encrypt SSL
Install Certbot, the Let's Encrypt client:
sudo apt install certbot python3-certbot-nginx -y
Obtain and install an SSL certificate:
sudo certbot --nginx -d your.domain.com
Certbot will automatically configure Nginx to use the new SSL certificate. After the process is complete, you should be able to access Collabora Online at https://your.domain.com.
Integrate Collabora Online with Nextcloud
To use Collabora Online with Nextcloud, follow these steps:
Install the Collabora Online app in Nextcloud:
- Go to the Nextcloud Apps settings.
- Enable the "Collabora Online" app.
Configure the Collabora Online app:
- Go to the Nextcloud Admin settings.
- Open the "Collabora Online" section.
- Enter the URL of your Collabora Online server (e.g., https://your.domain.com).
Conclusion
You have successfully deployed Collabora Online on your Ubuntu server. Your users can now collaborate on documents in real-time using this powerful online office suite. For further customization and advanced configurations, refer to the Collabora Online documentation.
