Docker image
This directory contains the files that are used to build the official Docker image on https://hub.docker.com/r/etherpad/etherpad.
Rebuilding with custom settings
In order to use a personalized settings file, you will have to rebuild your image.
All of these instructions are as a member of the docker group.
Prepare your custom settings.json file:
cd <BASEDIR>/docker
cp ../settings.json.template settings.json
[ further edit your settings.json as needed]
Each configuration parameter can also be set via an environment variable, using the syntax "${ENV_VAR}" or "${ENV_VAR:default_value}". For details, refer to settings.json.template.

# builds latest development version
docker build --tag <YOUR_USERNAME>/etherpad .
