Setting heap size using the Docker images

[Phandora (Mayte)]

Hi everyone,

I am using Elasticsearch 7.10.0 version on EKS. I need to manually set the heap size since Elasticsearch does not automatically sizes JVM heap until 7.11 version.

It is recommended that the heap size should be no more than 50% of available RAM and no more than 32GB but, are these values equally valid for EKS?

Does this mean that I should not set a heap size greater than 50% of available RAM visible to the container?

Any assistance will be greatly appreciated.

Regards!

Yes. This is valid for any Elasticsearch deployment. Note that the threshold is less than 32GB, potentially around 30GB.
