|
|
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.
|
|
This policy ensures that only those "safe" subsets can be specified in
|
|
a Pod.
