Or grab it like this:

$ docker pull collabora/code
$ docker run -t -d -p 127.0.0.1:9980:9980 -e "domain=<your-dot-escaped-domain>" \
        -e "username=admin" -e "password=S3cRet" --restart always --cap-add MKNOD collabora/code

<your-dot-escaped-domain> is the WOPI host, i.e. your preferred File Sync and Share solution that implements WOPI protocol, for example share\\.example\\.com. You need double backslash in command line, because shell escapes the first, and the domain parameter takes a regular expression. Note: you can enable multiple domains by separating the domain names with | character.
The optional username and password parameters enable the admin console feature of CODE. You can access the admin console at https://<CODE-domain>/loleaflet/dist/admin/admin.html.

Other optional environment variables that you can pass to collabora/code

If you need to tweak other parameters of CODE, you can edit the configuration file /etc/loolwsd/loolwsd.xml in the Docker image, it is self documented.

If you need customizations, for example additional fonts, you can build the docker image yourself. See the source on GitHub. Add font packages to install-libreoffice.sh script, then build a custom image.

Now you can give https://collabora.example.com as the WOPI URL in your preferred File Sync and Share solution. See below for specific examples.

What next ?

That’s it – once you’ve integrated your docker image with your preferred File Sync and Share (FSS), or started up your VM you should be setup to share and collaborate on your own documents, with friends, from the comfort of your own home.

So now you’re all happy and secure, why not participate in the project?
