Install the venerable LibreOffice via Docker from NAT VPS

NATVPS.id – LibreOffice is office software (office) which is free, modern, and open source. LibreOffice can be an alternative to Microsoft Office and WPS Office.

This article discusses the steps to install LibreOffice via picture Docker on the NAT VPS, so you can access it via web browser. This article uses Ubuntu 22.04 as a reference, but you can use other distributions such as Debian and CentOS.

Port Forwarding Configuration

Considering we are using NAT, we need to add 2 port forwarding configurations on the Virtualizor panel (or other VPS panel according to provider), ie HTTP and HTTPS port forwarding for LibreOffice domains.

For example, this article will use domains libreoffice.tutorial.mdinata.my.id for LibreOffice. You are free to change the domain according to your choice. Note this domain, because we will use it again in the installation process.

Don’t forget to add a DNS record that goes to your VPS’ NAT public IP, like this:

Install Docker

We will use Docker and Docker Compose for spread LibreOffice.

First, Install curly using the command:

apt update && apt install curl -y

Then, run it script automatic installation of Docker by entering:

curl -fsSL get.docker.com | sh

Wait until the installation process is complete.

Install LibreOffice

First, create a new directory for LibreOffice:

mkdir /opt/libreoffice
cd /opt/libreoffice

Then, create a Docker Compose file:

apt install nano -y # Jika belum
nano docker-compose.yml

Fill in the following configuration:

# 

services:
  libreoffice:
    image: lscr.io/linuxserver/libreoffice:latest
    container_name: libreoffice
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Jakarta
    volumes:
      - ./config:/config
    ports:
      - 3000:3000
      - 3001:3001
    shm_size: "1gb"
    restart: unless-stopped

Save the file with Ctrl-X, yThen Enter.

Finally, run LibreOffice:

docker compose up -d

Wait for the process spread finished. The first deployment may take a few minutes due to downloading picture LibreOffice.

NGINX (Reverse Proxy) Configuration

LibreOffice requires an encrypted connection using HTTPS for security. So that we can access URLs with HTTPS via domains such as https://libreoffice.tutorial.mdinata.my.idwe can use reverse proxy like NGINX.

First, install NGINX via command:

# Hapus Apache2 dan pendukungnya (biasanya terpasang secara bawaan di VPS OpenVZ)
apt purge apache2* -y

# Install NGINX
apt install nginx -y

Create a new host configuration specifically for LibreOffice:

nano /etc/nginx/sites-available/libreoffice

Then paste the following configuration:

# 
server {
    listen 80;
    server_name libreoffice.tutorial.mdinata.my.id;

    location / {
        proxy_pass 
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_redirect off;
        proxy_buffers 8 32k;
        proxy_buffer_size 64k;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
    }
}

Change libreoffice.tutorial.mdinata.my.id with your domain.

Activate the configuration by:

ln -sf /etc/nginx/sites-available/libreoffice /etc/nginx/sites-enabled/

# Restart NGINX
systemctl restart nginx

Generate SSL Certificate (Let’s Encrypt)

In order for our domain to be accessible via HTTPS, we need to create an SSL certificate. We can use a free SSL certificate from Let’s Encrypt via Certbot.

Install Certbot and its NGINX plugin use the command:

apt install python3-certbot python3-certbot-nginx

So, produce certificate via Certbot with command

certbot --nginx -d libreoffice.tutorial.mdinata.my.id

Change libreoffice.tutorial.mdinata.my.id with your domain.

Happy! LibreOffice can currently be accessed via a secure HTTPS connection.

Access LibreOffice

LibreOffice can be accessed through your previous domain. Example: https://libreoffice.tutorial.mdinata.my.id.
