Updating

You can change the version used for solr by modifying the build argument SOLR_VERSION and SOLR_FILE_SHA256 in the Dockerfile.

Change SOLR_VERSION and then generate the SOLR_FILE_SHA256 with the following commands:

SOLR_VERSION=$(cat solr/Dockerfile | grep -o 'SOLR_VERSION=.*' | cut -f2 -d=)
SOLR_FILE=$(cat solr/Dockerfile | grep -o 'SOLR_FILE=.*' | cut -f2 -d=)
SOLR_URL=$(cat solr/Dockerfile | grep -o 'SOLR_URL=.*' | cut -f2 -d=)
SOLR_FILE=$(eval "echo $SOLR_FILE")
SOLR_URL=$(eval "echo $SOLR_URL")
wget --quiet "${SOLR_URL}"
shasum -a 256 "${SOLR_FILE}" | cut -f1 -d' '
rm "${SOLR_FILE}"
