Supported Versions

  • 5.5
  • 6.6
  • 7.7

Lagoon & OpenShift adaptions

This image is prepared to be used on Lagoon, which leverages OpenShift. There are therefore some things already done:

  • Folder permissions are automatically adapted with fix-permissions, so this image will work with a random user, and therefore also on OpenShift.
  • 10-solr-port.sh script to fix and check Solr port.
  • 20-solr-datadir.sh script to check if Solr config is compliant for Lagoon.

Environment Variables

Environment variables defined in Solr base image.

Environment Variable Default Description
SOLR_JAVA_MEM 512M Default Java HEAP size (ie. SOLR_JAVA_MEM="-Xms10g -Xmx10g" ).
SOLR_DATA_DIR /var/solr Path of the solr data dir, be careful, changing this can occur data loss!
SOLR_COPY_DATA_DIR_SOURCE unset Path which the entrypoint script of solr will use to copy into the defined SOLR_DATA_DIR, this can be used for prepopulating the Solr with a core. The scripts expects actual Solr data files! Plus it only copies data if the destination does not already have a solr core in it.
