Collabora Online - Built-in CODE Server (for Nextcloud)

Created by Collabora Productivity Ltd.

• This app provides a built-in server with all of the document editing features of Collabora Online.
• Easy to install, for personal use or for small teams.
• A bit slower than a standalone server and without the advanced scalability features.

Collabora Online is a powerful LibreOffice-based online office suite with collaborative editing, which supports all major documents, spreadsheet and presentation file formats and works together with all modern browsers.

The included CODE Server app is provided as an AppImage. When running under Docker/LXC the AppImage will be unpacked and run, else the host is required to be able to run AppImages which adds a requirement on FUSE.

Notes:

• If the app is built with an ARM64 AppImage, it will be named richdocumentscode_arm64.
• On slower systems, the first time the CODE Server is started there may be a noticeable delay (also applies on subsequent runs if /tmp whenever cleared)

• Linux x86-64 or ARM64 (aarch64) platform
• 2 CPU cores
• 1 GB RAM + 100 MB RAM / user
• 100 kbit/s network bandwidth / user
• 300 MB space on disk (800 MB in /tmp if not using FUSE)
• Nextcloud 19 with the Nextcloud Office app 3.7.0 or higher
• A glibc based distribution/container (AppImage does not support musl libc)
• Fontconfig (libfontconfig.so.1 - required by Collabora_Online.AppImage)

• Kernel supporting the FUSE (Filesystem in Userspace)
• FUSE 2 (libfuse.so.2)

Note: If FUSE support is not present, a warning (dlopen(): error loading libfuse.so.2) will be generated, but then the AppImage will be started with the --appimage-extract-and-run parameter automatically as a fallback.

The download is rather big (~300 MB) so it is possible you will experience a time-out if using the web interface to install from the AppStore. Using the OCC command line tool is suggested for reliability:

sudo -u wwwrun php -d memory_limit=512M ./occ app:install richdocumentscode

Where wwwrun is the user of your web server. This is www-data on Debian, Ubuntu and derivatives, wwwrun on SUSE based distributions, apache on Red Hat/Fedora and http on Arch linux and derivatives. Updates can be done like this:

sudo -u wwwrun php -d memory_limit=512M ./occ app:update --all

Of course, alternatively you could increase memory usage and PHP time-outs by default, see the Nextcloud documentation.

• Make sure you have enough disk space
• Check the logs:
  • nextcloud.log
  • container logs (if applicable)
  • /tmp/coolwsd.*/coolwsd.log (on your host or in the container's /tmp if applicable)
