# Appendix - Docker Tweaks

Beside of original Apache Solr Docker image, on which is our image based on we provide some tweaks to make our and your work simpler.

## Disable unnecessary cores on container start

By defining env `TYPO3_SOLR_ENABLED_CORES` with a space separated list of languages/cores to enable, only those cores will be initialized on start-up.
This allows to save memory usage of Apache Solr server instance.

Usage:

```bash
docker run -e 'TYPO3_SOLR_ENABLED_CORES=english german' -it typo3solr/ext-solr
```
