Docker

The official Docker image is available on https://hub.docker.com/r/etherpad/etherpad.

Downloading from Docker Hub

If you are ok downloading a prebuilt image from Docker Hub, these are the commands:

# gets the latest published version
docker pull etherpad/etherpad

# gets a specific version
docker pull etherpad/etherpad:1.8.0

Build a personalized container

If you want to use a personalized settings file, you will have to rebuild your image. All of the following instructions are as a member of the docker group.

Rebuilding with custom settings

Edit <BASEDIR>/settings.json.docker at your will. When rebuilding the image, this file will be copied inside your image and renamed to setting.json.

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.

Rebuilding including some plugins

If you want to install some plugins in your container, it is sufficient to list them in the ETHERPAD_PLUGINS build variable. The variable value has to be a space separated, double quoted list of plugin names (see examples).

Some plugins will need personalized settings. Just refer to the previous section, and include them in your custom settings.json.docker.

Examples

Build a Docker image from the currently checked-out code:

docker build --tag <YOUR_USERNAME>/etherpad .

Include two plugins in the container:

docker build --build-arg ETHERPAD_PLUGINS="ep_codepad ep_author_neat" --tag <YOUR_USERNAME>/etherpad .

Running your instance:

To run your instance:

docker run --detach --publish <DESIRED_PORT>:9001 <YOUR_USERNAME>/etherpad

And point your browser to http://<YOUR_IP>:<DESIRED_PORT>

Options available by default

The settings.json.docker available by default enables some configuration to be set from the environment.

Available options:

  • TITLE: The name of the instance
  • FAVICON: favicon default name, or a fully specified URL to your own favicon
  • SKIN_NAME: either no-skin, colibris or an existing directory under src/static/skins.
  • IP: IP which etherpad should bind at. Change to :: for IPv6
  • PORT: port which etherpad should bind at
  • SHOW_SETTINGS_IN_ADMIN_PAGE: hide/show the settings.json in admin page
  • DB_TYPE: a database supported by https://www.npmjs.com/package/ueberdb2
  • DB_HOST: the host of the database
  • DB_PORT: the port of the database
  • DB_NAME: the database name
  • DB_USER: a database user with sufficient permissions to create tables
  • DB_PASS: the password for the database username
  • DB_CHARSET: the character set for the tables (only required for MySQL)
  • DB_FILENAME: in case DB_TYPE is DirtyDB, the database filename. Default: var/dirty.db
  • ADMIN_PASSWORD: the password for the admin user (leave unspecified if you do not want to create it)
  • USER_PASSWORD: the password for the first user user (leave unspecified if you do not want to create it)
  • TRUST_PROXY: set to true if you are using a reverse proxy in front of Etherpad (for example: Traefik for SSL termination via Let's Encrypt). This will affect security and correctness of the logs if not done
  • LOGLEVEL: valid values are DEBUG, INFO, WARN and ERROR

Examples

Use a Postgres database, no admin user enabled:

docker run -d \
	--name etherpad         \
	-p 9001:9001            \
	-e 'DB_TYPE=postgres'   \
	-e 'DB_HOST=db.local'   \
	-e 'DB_PORT=4321'       \
	-e 'DB_NAME=etherpad'   \
	-e 'DB_USER=dbusername' \
	-e 'DB_PASS=mypassword' \
	etherpad/etherpad

Run enabling the administrative user admin:

docker run -d \
	--name etherpad \
	-p 9001:9001 \
	-e 'ADMIN_PASSWORD=supersecret' \
	etherpad/etherpad

Run a test instance running DirtyDB on a persistent volume:

docker run -d \
	-v etherpad_data:/opt/etherpad-lite/var \
	-p 9001:9001 \
	etherpad/etherpad
