On supported hosts, the 'runtime/default' AppArmor profile is applied by default.
|
|
The default policy should prevent overriding or disabling the policy, or restrict
|
|
overrides to an allowed set of profiles. This policy ensures Pods do not
|
|
specify any other AppArmor profiles than `runtime/default` or `localhost/*`.

Specifying other AppArmor profiles is disallowed. The annotation
