+## 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). 
+
+Here is an example that sets the AppArmor profile to the node's container runtime
+default profile:
+
+```yaml
+...
+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
+...
+securityContext:
+  appArmorProfile:
+    type: Localhost
+    localhostProfile: k8s-apparmor-example-deny-write
+```
+
+For more details please see, [Restrict a Container's Access to Resources with AppArmor](/docs/tutorials/security/apparmor/).
