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.
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...
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!
Enterprise users who need a more reliable and scalable solution with long term support, guaranteed response times and security updates can take advantage of our optional support contract for Collabora Online.
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\\.nexcloud\\.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
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
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 Lets 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
Some common issues:
docker logs id-of-your-instance). If the logs note something like:
No acceptable WOPI hosts found matching the target host [YOUR NEXTCLOUD DOMAIN] in config.
Unauthorized WOPI host. Please try again later and report to your administrator if the issue persists.
Connection is not allowederrors.
We are sorry, this is an unexpected connection error. Please try again.error.
