    • Tune net.ipv4.ip_local_port_range to 1024 65535 as a safe sysctl.
    • Tune net.core.somaxconn to 32768 via an initContainer with privilege escalation.

  • Connectivity ingress-nginx-app v1.6.8

    Changed

    • Default max-worker-connections to 0, making it same as max-worker-open-files i.e. max open files (system's limit) / worker-processes - 1024. This optimizes for high load conditions where it improves performance at the cost of increasing RAM utilization (even on idle).
    • HorizontalPodAutoscaler was tuned to use targetMemoryUtilizationPercentage of 80 due to increased RAM utilization with new default for max-worker-connections of 0.
