### Overwrite world on start
The world will only be downloaded or copied if it doesn't exist already. Set `FORCE_WORLD_COPY=TRUE` to force overwrite the world on every server start.
### Custom worlds directory path
To set a custom worlds directory for the Multiverse plugin on a baremetal server, you'd pass the `--world-dir` argument after the jar file.
In order to accomplish the same in a containerized server, set the `EXTRA_ARGS` environment variable in your command line or docker compose yaml to the same argument string. For example:
```
docker run -d -e EXTRA_ARGS='--world-dir ./worlds/'
```
`--world-container`, `-W`, and `--universe` are aliases to `--world-dir` and can also be used.
### Datapacks
Datapacks can be installed in a similar manner to mods/plugins. There are many environment variables which function in the same way they do for [mods](#working-with-mods-and-plugins):

For some cases, if e.g. after removing mods, it could be necessary to startup minecraft with an additional `-D` parameter like `-Dfml.queryResult=confirm`. To address this you can use the environment variable `JVM_DD_OPTS`, which builds the params from a given list of values separated by space, but without the `-D` prefix. To make things running under systems (e.g. Plesk), which doesn't allow `=` inside values, a `:` (colon) could be used instead. The upper example would look like this:
`JVM_DD_OPTS=fml.queryResult:confirm`, and will be converted to `-Dfml.queryResult=confirm`.
### Jarfile Options
Options that would usually be passed to the jar file (those which are written after the filename) can be passed via the `EXTRA_ARGS` environment variable.
See [Custom worlds directory path](#custom-worlds-directory-path) for an example.
### Interactive and Color Console
If you would like to `docker attach` to the Minecraft server console with color and interactive capabilities, then add
