The docker image cubeengine/sponge sets up a sponge vanilla minecraft server containing Sponge Vanilla
This documentation only describes how to set up the docker container. Have a look at the related GitHub projects to get more details about the actual functionality:
To persist the data you must mount a few volumes which are listed below:
/home/minecraft/root- This directory only contains the filesbanned-ips.json,banned-players.json,ops.jsonandwhitelist.jsonof the server root directory./home/minecraft/world- This directory stores the heart of the server - the minecraft world(s)./home/minecraft/config- Here are the configuration files. You might edit them to set up your server correctly./home/minecraft/logs- This directory contains the server logs./home/minecraft/mods- This directory is your space to store any additional sponge mods.
The container can be configured using environment variables.
One important mention is the JAVA_VM_ARGS environment variable. This helps you to specify additional arguments for the java process. By default, it doesn't contain anything. As a suggestion I advise you to set the Xmx variable, the maximum size of the memory allocation pool at least 2G or 3G. For this just write JAVA_VM_ARGS=-Xmx2G
You might have noticed that the root-volume doesn't contain the server.properties file. This file doesn't need to be persisted because it can be set up using environment variables. Below you'll find a list of the environment variable names. A description of them, supported values and default behaviours can be found on the minecraft-wiki.

Some of the Sponge plugins may need a database connection. The database can be set up with the following variables. The list also shows the default values.
DB_ALIAS="jdbc:postgresql://user:password@localhost:5432/minecraft"- The alias under which the following connection string is placed in the sponge.confDB_CONNECTION_STRING="database- A connection string to a sql database.
When setting up your server initially you might want to give op to a list of players.
Set the environment variable OPS to a space separated list of usernames to op them.
This only works for the initial creation.
