Hi I am new to elastic search.
I searched a lot but not found documentation / article regarding auto scaling elastic search using kubernetes Vertical Pod Autoscaling.
I need to know whether I can do VPA with elastic search ?
According to the official google docs regarding the limitations of the Vertical Pod Autoscaling:
Vertical Pod autoscaling is not yet ready for use with JVM-based workloads due to limited visibility into actual memory usage of the workload.
and to the Elasticsearch documentation:
Elasticsearch is built using Java, and requires at least Java 8 in order to run. Only Oracle’s Java and the OpenJDK are supported. The same JVM version should be used on all Elasticsearch nodes and clients.
So I am afraid that combining these two is not a recommended way.
