Bringing self-hosted online office to everybody
Collabora Online is a powerful LibreOffice-based online office suite with collaborative editing, which supports all major document, spreadsheet and presentation file formats and works in all modern browsers.
We deployed Nextcloud with Collabora some months ago. We are very happy with the user-acceptance of the sync&share function and hope to expand on Collabora usage as part of our plans to make Nextcloud a core component of our digital-workspace initiative.

Collabora Online supports editing your documents in real time with multiple other editors, showing high fidelity, WYSIWYG rendering and preserving the layout and formatting of your documents.
Users can insert and reply to comments and invite others without a Nextcloud account for anonymous editing of files with a public link shared folder.
Collabora Online supports dozens of document formats including DOC, DOCX, PPT, PPTX, XLS, XLSX + ODF, Import/View Visio, Publisher and many more…

Collabora Online Development Edition (CODE) is free and under heavy development, adding features and improvements all the time, but beware that it is limited to 10 open documents only, so it is only suitable for small teams or as demo version! Enterprise users have access to the more stable, scalable Collabora Online Enterprise version through a Nextcloud support subscription.
Most people use online services for storing their data, communication and editing documents, often giving up control over their files in exchange for the convenience of online collaboration. With Nextcloud and Collabora Online, this is no longer a trade-off.
Collabora Online is Open Source, self-hosted and secure!
The users had no problems with Collabora Online; installing it had only a few tickets in half a year, it was easy to provide this service … it just works.

We are able to provide a solution for Online Office for the entire Nextcloud community through our partnership with Collabora in an easy to use docker image for developers and home users. Enterprise users looking for a more reliable solution should contact Nextcloud Sales.
We’ll describe how to get Collabora Online running on your server and how to integrate it into your Nextcloud using the docker image Nextcloud and Collabora built.
To install it the following dependencies are required:
Note: This guide does NOT cover self-signed certificates. If you use a self-signed certificate then you’re mostly on your own 😉
The following steps will download the Collabora Online docker, make sure to replace “cloud.nextcloud.com” with the host that your own Nextcloud runs on. Also make sure to escape all dots with double backslashes (
\), since this string will be evaluated as a regular expression (and your bash ‘eats’ the first backslash.) If you want to use the docker container with more than one Nextcloud, you’ll need to use
'domain=cloud\\.nextcloud\\.com\|second\\.nextcloud\\.com' instead. (All hosts are separated by
docker pull collabora/code docker run -t -d -p 127.0.0.1:9980:9980 -e 'domain=cloud\\.nextcloud\\.com' --restart always --cap-add MKNOD collabora/code
Optionally, you can select the dictionaries you want with:
docker run -t -d -p 127.0.0.1:9980:9980 -e 'domain=cloud\\.nextcloud\\.com' -e 'dictionaries=de en es ..' --restart always --cap-add MKNOD collabora/code
This way you are not only limited to German, English, Italian, French and Spanish.
That will be enough. Once you have done that the server will listen on “localhost:9980”. Now we just need to configure the locally installed Apache reverse proxy.
On a recent Ubuntu or Debian this should be possible using:
apt-get install apache2
Warning, if you are using Nextcloud 23 (Nextcloud HUB II), the VirtualHost configuration has changed. You can find the latest installation information on Collabora Online official documentation.
Afterward, configure one VirtualHost properly to proxy the traffic. For security reason we recommend to use a subdomain such as office.nextcloud.com instead of running on the same domain. An example config can be found below:
<VirtualHost *:443> ServerName office.nextcloud.com:443 # SSL configuration, you may want to take the easy route instead and use Let's Encrypt!

After configuring these do restart your apache using
Occasionally, new versions of this docker image are released with security and feature updates. We will of course let you know when that happens! This is how you upgrade to a new version:
docker pull collabora/code
docker stop CONTAINER_ID
docker rm CONTAINER_ID
docker run -t -d -p 127.0.0.1:9980:9980 -e 'domain=cloud\\.nextcloud\\.com' --restart always --cap-add MKNOD collabora/code
