 #### Attributes
 
 * `host` - Host is the fully qualified domain name of a network host, as defined by RFC 3986. Note the following deviations from the \"host\" part of the URI as defined in the RFC: 1. IPs are not allowed. Currently an IngressRuleValue can only apply to the IP in the Spec of the parent Ingress. 2. The : delimiter is not respected because ports are not allowed. Currently the port of an Ingress is implicitly :80 for http and :443 for https. Both these may change in the future. Incoming requests are matched against the host before the IngressRuleValue. If the host is unspecified, the Ingress routes all traffic based on the specified IngressRuleValue.
-* `http` - http is a list of http selectors pointing to backends. In the example: http:///? -> backend where where parts of the url correspond to RFC 3986, this resource will be used to match against everything after the last '/' and before the first '?' or '#'. See `http` block attributes below.

 * `priority_class_name` - If specified, indicates the pod's priority. 'system-node-critical' and 'system-cluster-critical' are two special keywords which indicate the highest priorities with the formerer being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.
 * `restart_policy` - Restart policy for all containers within the pod. One of Always, OnFailure, Never. For more info see [Kubernetes reference](http://kubernetes.io/docs/user-guide/pod-states#restartpolicy).
 * `security_context` - (SecurityContext holds pod-level security attributes and common container settings. Optional: Defaults to empty
-* `service_account_name` - ServiceAccountName is the name of the ServiceAccount to use to run this pod. For more info see http://releases.k8s.io/HEAD/docs/design/service_accounts.md.
+* `service_account_name` - ServiceAccountName is the name of the ServiceAccount to use to run this pod. For more info see https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/.
 * `share_process_namespace` - Share a single process namespace between all of the containers in a pod. When this is set containers will be able to view and signal processes from other containers in the same pod, and the first process in each container will not be assigned PID 1. HostPID and ShareProcessNamespace cannot both be set.
 * `subdomain` - If specified, the fully qualified Pod hostname will be "...svc.". If not specified, the pod will not have a domainname at all..
 * `termination_grace_period_seconds` - Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process.
@@ -99,7 +99,7 @@ The following arguments are supported:
 * `port` - List of ports to expose from the container. Exposing a port here gives the system additional information about the network connections a container uses, but is primarily informational. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Cannot be updated.
 * `readiness_probe` - Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. For more info see [Kubernetes reference](http://kubernetes.io/docs/user-guide/pod-states#container-probes)
 * `resources` - Compute Resources required by this container. Cannot be updated. For more info see [Kubernetes reference](http://kubernetes.io/docs/user-guide/persistent-volumes#resources)

+* `security_context` - Security options the pod should run with. For more info see https://kubernetes.io/docs/tasks/configure-pod-container/security-context/.
 * `stdin` - Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF.
 * `stdin_once` - Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF.
 * `termination_message_path` - Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Defaults to /dev/termination-log. Cannot be updated.

 * `external_traffic_policy` - (Optional) Denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints. `Local` preserves the client source IP and avoids a second hop for LoadBalancer and Nodeport type services, but risks potentially imbalanced traffic spreading. `Cluster` obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading. For more info: https://kubernetes.io/docs/tutorials/services/source-ip/
 * `load_balancer_ip` - Only applies to `type = LoadBalancer`. LoadBalancer will get created with the IP specified in this field.
