Elasticsearch in HCL Connections Componentpack is secured with Searchguard and needs certificates to work properly. These certificates are generated by bootstrap during the initial container deployment with
These certificates are valid for 10 years (

CVE-2021-44228 was a very serious problem end of 2021, and we are still finding new occurrences, or security teams scan servers and find vulnerable log4j files. Don’t get me wrong most of these occurrences are not vulnerable any more, because the JVM is hardened like in the Elasticsearch 7 containers, or they use of the JVM parameter
Today I activated Elasticsearch Metrics and Typeahead Search on my demo HCL Connections cluster .
To my surprise the indices weren’t created and I got errors on the
I checked the Elasticsearch pods which showed a running state, but the logs showed following messages:
