Nextcloud with LibreOffice Online

This docker configuration help with setting up Nextcloud with LibreOffice Online for testing purposes. It keeps things as simple as possible (no https e.g.).

Preparations

To get started, you need two virtual machines with two different hostnames. Install some recent Linux distro on them, e.g. Ubuntu 18.04 (64bit required).

Install docker and docker-compose on them.

Then clone this repo. You need the folder nextcloud on one machine and the folder libreoffice-online on the other machine.

Setup Nextcloud

Go to the folder nextcloud. If you want to set up nextcloud with a MariaDB database, copy the .env.sample to .env and set the environment variables accordingly. Note that the database host is called 'db'.

If you want to use sqlite instead, you can skip this step.

Run docker-compose up -d. This will setup Nextcloud and the database for you.

Now configure Nextcloud in your web browser. It's available on http://yourhost:80 You can change the port in docker-compose.yml.

When nextcloud is set up, install the App "Collabora Online". Then go to Configuration->Collabora Online and enter the domain name of your other VM, e.g. http://libreoffice.yourhost:9980

Setup LibreOffice Online

On your other VM, go to the folder "libreoffice-online".

Copy the .env.sample to .env and set the environment variables accordingly.

• NEXTCLOUD_DOMAIN must be set to the domain where your nextcloud is running, e.g. yourhost in this example.
• LO_ONLINE_USERNAME and LO_ONLINE_PASSWORD are used to access the LibreOffice Online dashboard (not absolutely necessary).

Once set, run docker-compose up -d. This will start LibreOffice online with SSL disabled.

Configuration changes

The configuration is stored in a docker volume. This way LibreOffice Online can be configured on the host system and the config will not be overwritten when updating the docker container.

The volume is created by docker-compose. You can find the volume name via: docker volume ls (eg. libreoffice-online_config-volume). Finally, find the location of the config file with docker volume inspect <volume_name>. You should see the mount point, for example: /var/lib/docker/volumes/libreoffice-online_config-volume/_data. The file loolwsd.xml in that directory is the main config file.

Edit it to your liking, then restart the container: docker-compose restart

Using it

You should now be able to edit documents in your nextcloud with LibreOffice online. Create a document using the '+' button or upload some.

To access the LibreOffice Online admin dashboard, visit http://libreoffice.yourhost:9980/loleaflet/dist/admin/admin.html and use the credentials from your .env file.

To test just LibreOffice Online without using Nextcloud, visit http://libreoffice.yourhost:9980/loleaflet/dist/loleaflet.html?file_path=file:///opt/libreoffice/share/template/common/internal/idxexample.odt . Note that you have to allow local file access for this to work. Look for storage/filesystem in the config.

Updating

To get the latest version, run the following two commands:

docker-compose pull
docker-compose up -d --build

Troubleshooting

If it doesn't work, look at the logs from your docker containers, easiest with: docker-compose logs
