Can we modify kernal parameters underlying virtual machine for their managed Kubernetes service.

You can't modify kernel parameters of the underlying virtual machine for their managed Kubernetes service. To overcome this limitation, use a privileged Init Container to set the values in the container's net namespace or run a DaemonSet on every node with privileged containers to modify non-namespaced sysctls. For example, launch an Init Container using the following code:

      ```
      initContainers:
        - command:
          - /bin/sh
          - -c
          - |
            sysctl -w net.core.somaxconn=10000
        image: busybox
        imagePullPolicy: Mas
        name: init-sysctl
        resources: {}
        securityContext:
          privileged: true
      ```
      Note: Kubernetes doesn't allow updates in securityContext for non-namespaced sysctls.
