Etherpad Lite image for docker

This image uses an mysql container for the backend for the pads. It is based on latest nodejs image.

About Etherpad Lite

From the official website:

Etherpad allows you to edit documents collaboratively in real-time, much like a live multi-player editor that runs in your browser. Write articles, press releases, to-do lists, etc. together with your friends, fellow students or colleagues, all working on the same document at the same time.

All instances provide access to all data through a well-documented API and supports import/export to many major data exchange formats. And if the built-in feature set isn't enough for you, there's tons of plugins that allow you to customize your instance to suit your needs.

You don't need to set up a server and install Etherpad in order to use it. Just pick one of publicly available instances that friendly people from everywhere around the world have set up. Alternatively, you can set up your own instance by following our installation guide

Quickstart

Copy-paste the following content in a docker-compose.yml file

---
version: "3.4"

services:
  db:
    image: mariadb:10.3
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    volumes:
      - db_data:/var/lib/mysql
    environment:
      MARIADB_ROOT_PASSWORD: insecure
      MARIADB_DATABASE: etherpad

  etherpad:
    build:
      context: .
      dockerfile: Dockerfile
    image: glenux/etherpad:latest
    environment:
      DATABASE_URL: mysql://root:insecure:3306@db/etherpad
      ETHERPAD_ADMIN_USER: admin
      ETHERPAD_ADMIN_PASSWORD: insecure
      NODE_ENV: production
    ports:
      - 9001:9001

volumes:
  db_data:

Then run docker-compose up

Etherpad will automatically create an etherpad database in the specified mysql server if it does not already exist.

You can now access Etherpad Lite from http://localhost:9001/
