# Introduction

This will build a container for [LibreOffice Online](https://libreoffice.org/) for editing documents in a browser from supported applications

* This Container uses a [customized Debian Linux base](https://hub.docker.com/r/tiredofit/debian) which includes [s6 overlay](https://github.com/just-containers/s6-overlay) enabled for PID 1 Init capabilities, [zabbix-agent](https://zabbix.org) for individual container monitoring, Cron also installed along with other tools (bash,curl, less, logrotate, nano, vim) for easier management.

* Configurable Concurrent User and Document Limit (set to generarous values by default)
* Set features to support autogeneration of TLS certificates/activate reverse proxy support, others..
* 
* Zabbix Monitoring of Active Documents, Users, Memory Consumed

# Prerequisites

This image assumes that you are using a reverse proxy such as [jwilder/nginx-proxy](https://github.com/jwilder/nginx-proxy) and optionally the [Let's Encrypt Proxy Companion @ https://github.com/JrCs/docker-letsencrypt-nginx-proxy-companion](https://github.com/JrCs/docker-letsencrypt-nginx-proxy-companion) in order to serve your pages. However, it will run just fine on it's own if you map appropriate ports.


# Installation

Automated builds of the image are available on [Docker Hub](https://hub.docker.com/tiredofit/libreoffice-online) and is the 
recommended method of installation.

If you decide to compile this, it will take quite a few hours.


```bash
docker pull tiredofit/libreoffice-online
```

The following image tags are available:

* `latest` - See most recent versioned tag
* `1.4` - Collabora Libreoffice 6.0.30 with Collabora Office Online 4.0.4-1
* `1.1` - Collabora Libreoffice 5.3.61 with Collabora Office Online 3.4.2.1

# Quick Start

* The quickest way to get started is using [docker-compose](https://docs.docker.com/compose/). See the examples folder for a working [docker-compose.yml](examples/docker-compose.yml) that can be modified for development or production use.

* Set various [environment variables](#environment-variables) to understand the capabilities of this image. A Sample `docker-compose.yml` is provided that will work right out of the box for most people without any fancy optimizations.

* Map [persistent storage](#data-volumes) for access to configuration and data files for backup.

# Configuration

### Persistent Storage

The following directories should be mapped for persistent storage in order to utilize the container effectively.

| Folder    | Description |
|-----------|-------------|
| `/var/log/loolwsd` | Log files
| `/assets/custom` | If you want to update the theme of LibreOffice online, dropping files in here will overwrite /opt/lool/share on startup |
### Environment Variables
