This project provides a xjoin-es-exporter image based on ubi8/ubi-minimal to fulfill Red Hat's security compliance. The elasticsearch_exporter in this project was copied from quay.io/cloudservices/xjoin-es-exporter:f621527 because the Dockerfile or the source project producing this image is unknown. The xjoin-es-exporter:f621527 image was built 3 years ago and the SECURITY SCAN at quay.io shows this image:tag as Unsupported, the ubi-minimal based image shows one "medium" vulnerability which has a fix available in "0:2.9.7-15.el8_7.1"
If elasticsearch_exporter requires an update in future, then try rebuilding it using https://github.com/prometheus-community/elasticsearch_exporter/ as this is the closest match discovered.
