Prerequisites and Assumptions
Installation
Build from Source
-
Clone this repository and build the image with
docker build <arguments> (imagename) . -
If you decide to compile this, it will take quite a few hours even on the fastest computer due to the amount of data required to download to compile. At some stages this image will grow to 30GB before shedding most of it for it's final size.
Prebuilt Images
Builds of the image are available on Docker Hub and is the recommended method of installation.
docker pull tiredofit/collabora-online:(imagetag)The following image tags are available along with their tagged release based on what's written in the Changelog:

Multi Architecture
Images are built primarily for amd64 architecture, and may also include builds for arm/v7, arm64 and others. These variants are all unsupported. Consider sponsoring my work so that I can work with various hardware. To see if this image supports multiple architecures, type docker manifest (image):(tag)
Configuration
Quick Start
- The quickest way to get started is using docker-compose. See the examples folder for a working docker-compose.yml that can be modified for development or production use.
- Set various environment variables to understand the capabilities of this image. A Sample
docker-compose.ymlis provided that will work right out of the box for most people without any fancy optimizations. - Map persistent storage for access to configuration and data files for backup.
- Make sure you set your hostname e.g. online.example.com when starting your container to make sure the administration console urls are correct.
Persistent Storage
The following directories should be mapped for persistent storage in order to utilize the container effectively.
| Folder | Description |
|---|---|
/logs/ |
Log files |
/assets/custom |
If you want to update the theme of Collabora online, dropping files in here will overwrite /opt/cool/share on startup |
/assets/custom-fonts |
(Optional) If you want to include custom truetype fonts, place them in this folder |
/assets/custom-scripts |
(Optional) If you want to execute a bash script before the application starts, drop your files here |
/etc/coolwsd/certs |
(Optional) If you would like to use your own certificates, map this volume and set appropriate variables |
Environment Variables
Base Images used
This image relies on a Debian Linux base image that relies on an init system for added capabilities. Outgoing SMTP capabilities are handlded via msmtp. Individual container performance monitoring is performed by zabbix-agent. Additional tools include: bash,curl,less,logrotate,nano,vim.
