# 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:
```bash
cd <BASEDIR>/docker
cp ../settings.json.template settings.json
[ further edit your settings.json as needed]
```

Build the version you prefer:
```bash
# builds latest development version
docker build --tag <YOUR_USERNAME>/etherpad .

# builds latest stable version
docker build --build-arg ETHERPAD_VERSION=master --tag <YOUR_USERNAME>/etherpad .

# builds a specific version
docker build --build-arg ETHERPAD_VERSION=1.7.5 --tag <YOUR_USERNAME>/etherpad .

# builds a specific git hash
docker build --build-arg ETHERPAD_VERSION=4c45ac3cb1ae --tag <YOUR_USERNAME>/etherpad .
```
