Proposal

Elasticsearch recommend TCP retransmission timeout as important system configuration.
Can we get it out of the box in Elastic operator?
Today, I had to add an initContainer to configure it manually:

initContainers:
  - name: tcp-transmission-settings
  image: "busybox:1.36.0"
  imagePullPolicy: IfNotPresent
  command:
  - sysctl
  - -w
  - net.ipv4.tcp_retries2=5
  securityContext:
    privileged: true

The issue originally starts here.

Environment
