policies.kyverno.io/description: The Sysctl interface allows to modify kernel parameters at
|
|
runtime and in the pod can be specified under 'securityContext.sysctls'. If kernel parameters
|
|
in the pod are to be modified, should be handled cautiously, and policy with rules restricting
|
|
these options will be helpful. We can control minimum and maximum port that a network connection
|
|
can use as its source(local) port by checking 'net.ipv4.ip_local_port_range'.
