+## Set the AppArmor Profile for a Container
+
+To set the AppArmor profile for a Container, include the `appArmorProfile` field
+in the `securityContext` section of your Container. The `appArmorProfile` field
+is a
+[AppArmorProfile](/docs/reference/generated/kubernetes-api/{{< param "version"
+>}}/#apparmorprofile-v1-core) object consisting of `type` and `localhostProfile`.
+Valid options for `type` include `RuntimeDefault`(default), `Unconfined`, and
+`Localhost`. `localhostProfile` must only be set if `type` is `Localhost`. It
+indicates the name of the pre-configured profile on the node. The profile needs
+to be loaded onto all nodes suitable for the Pod, since you don't know where the
+pod will be scheduled. 
+Approaches for setting up custom profiles are discussed in
+[Setting up nodes with profiles](/docs/tutorials/security/apparmor/#setting-up-nodes-with-profiles).
+
+Note: If `containers[*].securityContext.appArmorProfile.type` is explicitly set 
+to `RuntimeDefault`, then the Pod will not be admitted if AppArmor is not
+enabled on the Node. However if `containers[*].securityContext.appArmorProfile.type`
+is not specified, then the default (which is also `RuntimeDefault`) will only
+be applied if the node has AppArmor enabled. If the node has AppArmor disabled
+the Pod will be admitted but the Container will not be restricted by the 
+`RuntimeDefault` profile.
+
+Here is an example that sets the AppArmor profile to the node's container runtime
+default profile:
+
+```yaml
+...
+containers:
+- name: container-1
+  securityContext:
+    appArmorProfile:
+      type: RuntimeDefault
+```
+
+Here is an example that sets the AppArmor profile to a pre-configured profile
+named `k8s-apparmor-example-deny-write`:
+
+```yaml
+...
+containers:
+- name: container-1
+  securityContext:
+    appArmorProfile:
+      type: Localhost
+      localhostProfile: k8s-apparmor-example-deny-write
+```
