Sysctls can disable security mechanisms or affect all containers on a
|
|
host, and should be disallowed except for an allowed "safe" subset. A
|
|
sysctl is considered safe if it is namespaced in the container or the
|
|
Pod, and it is isolated from other Pods or processes on the same Node.

Setting additional sysctls above the allowed type is disallowed.

than 'kernel.shm_rmid_forced', 'net.ipv4.ip_local_port_range',
