LibreOffice Online – How to Integrate

LibreOffice Online is powerful online office suite that supports all major document, spreadsheet and presentation file formats, which can be integrated into Imixs-Documents. Key features are collaborative editing and excellent office file format support.

LibreOffice Online is available as a Docker image and is developed by Collabora. Collabora is the community mainly developing the LibreOffice Online code. You can get the collabora docker image from here.

General information about the Docker Image from Collabora and an integration guide can be found [here(https://sdk.collaboraonline.com/docs/installation/CODE_Docker_image.html).

Setup with Docker-Compose

For test environments Imixs-Documents and Collabora can be setup with Docker-Compose. The following example shows a .yaml file inclduing both services:

version: "3.6"
services:

# PostgreSQL
  db:
    image: postgres:9.6.1
    environment:
      POSTGRES_PASSWORD: adminadmin
      POSTGRES_DB: office
    volumes: 
      - dbdata:/var/lib/postgresql/data

# Imixs-Documents
  imixs-documents:
    image: imixs/imixs-documents:latest
    depends_on:
      - db
    environment:
      JAVA_OPTS: "-Dnashorn.args=--no-deprecation-warning"
      POSTGRES_USER: "postgres"
      POSTGRES_PASSWORD: "adminadmin"
      POSTGRES_CONNECTION: "jdbc:postgresql://db/office"      
      TZ: "Europe/Berlin"
      LANG: "en_US.UTF-8"
      MAILGATEWAY: "localhost"
      # Collabora integration
      WOPI_PUBLIC_ENDPOINT: "http://localhost:9980/loleaflet/6a844e4/loleaflet.html?"
      WOPI_HOST_ENDPOINT: "http://imixs-documents:8080/api/wopi/"
    ports:
      - "8080:8080"
      - "9990:9990"
    volumes:
      - ./deployments:/opt/jboss/wildfly/standalone/deployments/

# Collabora 
  libreoffice-app:
    image: collabora/code:6.4.8.4
    container_name: libreoffice-app
    expose:
      - 9980
    ports:
      - "9980:9980"
    environment:
      - username=admin
      - password=adminadmin
    volumes:
      - ./configuration/collabora/loolwsd.xml:/etc/loolwsd/loolwsd.xml

To integrate LibreOffice Online into Imixs-Documents the following Environment Variables need to be set:

You can find the technical details about the Imixs WOPI Protocoll Adapter here.

In this example the configuration file ‘loolwsd.xml’ is mapped locally. The loolwsd.xml gives you varios ways to configure Collabora. You can find a copy of this file here

Note: The collabora office suite provides a lot more ways for a custom configuration and installation. Please find the the details in the official online help.
