I’m running Nextcloud on the smallest DigitalOcean Ubuntu 16.04 VS with 1GB RAM. Is that sufficient to also run Collabora? I can’t find system requirements anywhere.
Even though docker handles most of the time resources pretty well, it uses around
1 GB of storage (CODE image)
~150 MB RAM on the first document open.
~50 MB of RAM on later documents
I would suggest at least 2 GB of RAM.
Or you might hit resources exhaustion.

System requirements for Collabora CODE (in addition to Nextcloud itself)
Linux x86-64 or ARM64 (aarch64) platform
2 CPU cores
1 GB RAM + 100 MB RAM / user
100 kbit/s network bandwidth / user
350 MB space on disk
Nextcloud 19 with Collabora Online app 3.7.0 or higher
glibc (AppImage does not support musl libc)
Fontconfig (libfontconfig.so.1 - required by Collabora_Online.AppImage)
fyi some updates since your post:
- Since April 2024, (23.05.10) I believe RAM usage dropped by 20MB per user to about 30MB per user (assuming a typical mix of file sizes).
- Since about March 2024, Collabora have an application for the automatic up/down Scaling and Load Distribution management, very useful for the 100,000+ user deployments, info here.
- Since Oct 2022, (22.05.6) Collabora Online now also supports the ppc64le architecture, press release.
