We have delpoyed elastic cache version 8.17 and 8.19 in our env's where fluentd aggregator is running as stateful set with out any issue.
But when Elastic cache is deployed with docker.elastic.co/elasticsearch/elasticsearch:9.2.3 with fluentd:v1.19.1-debian-1.0 and fluentd:v1.18-debian-1
im getting error in the logs stating ruby path is not found due to which plugins are failing to install.
efk-upgrade-fluentd-aggregator-0.log
as we are planning for upgrade from 8-9 fluentd is blocking the upgrade.
