-Fairwinds' Polaris keeps your clusters sailing smoothly. It runs a variety of checks to ensure that
-Kubernetes pods and controllers are configured using best practices, helping you avoid
-problems in the future.
+Polaris is an open source policy engine for Kubernetes that validates and remediates resource configuration. It includes 30+ built in configuration policies, as well as the ability to build custom policies with JSON Schema. When run on the command line or as a mutating webhook, Polaris can automatically remediate issues based on policy criteria.
 
 Polaris can be run in three different modes:
-* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard), so you can audit what's running inside your cluster.
-* As an [admission controller](https://polaris.docs.fairwinds.com/admission-controller), so you can automatically reject workloads that don't adhere to your organization's policies.
-* As a [command-line tool](https://polaris.docs.fairwinds.com/infrastructure-as-code), so you can test local YAML files, e.g. as part of a CI/CD process.
-
+* As a [dashboard](https://polaris.docs.fairwinds.com/dashboard) - Validate Kubernetes resources against policy-as-code.

 ## Background
 
+### Liveness and Readiness Probes
 Readiness and liveness probes can help maintain the health of applications running inside Kubernetes. By default, Kubernetes only knows whether or not a process is running, not if it's healthy. Properly configured readiness and liveness probes will also be able to ensure the health of an application.
 
 Readiness probes are designed to ensure that an application has reached a "ready" state. In many cases there is a period of time between when a webserver process starts and when it is ready to receive traffic. A readiness probe can ensure the traffic is not sent to a pod until it is actually ready to receive traffic.
 
 Liveness probes are designed to ensure that an application stays in a healthy state. When a liveness probe fails, the pod will be restarted.
 
+### Image Pull Policy
 Docker's `latest` tag is applied by default to images where a tag hasn't been specified. Not specifying a specific version of an image can lead to a wide variety of problems. The underlying image could include unexpected breaking changes that break your application whenever the latest image is pulled. Reusing the same tag for multiple versions of an image can lead to different nodes in the same cluster having different versions of an image, even if the tag is identical.
 
 Related to that, relying on cached versions of a Docker image can become a security vulnerability. By default, an image will be pulled if it isn't already cached on the node attempting to run it. This can result in variations in images that are running per node, or potentially provide a way to gain access to an image without having direct access to the ImagePullSecret. With that in mind, it's often better to ensure the a pod has `pullPolicy: Always` specified, so images are always pulled directly from their source.
 
+### Topology Spread Constraints
+
+By default, the Kubernetes scheduler uses a bin-packing algorithm to fit as many pods as possible into a cluster. The scheduler prefers a more evenly distributed general node load to app replicas precisely spread across nodes. Therefore, by default, multi-replica is not guaranteed to be spread across multiple availability zones. Kubernetes provides topologySpreadConstraint configuration in order to better ensure pod spread across multiple AZs and/or Hosts.
+
+Example of a topologySpreadConstraint spreading across zones:
+
+```
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: demo-basic-demo
+spec:
+  selector:
+    matchLabels:
+      app.kubernetes.io/name: basic-demo
+      app.kubernetes.io/instance: demo
+  template:
+    metadata:
+      labels:
+        app.kubernetes.io/name: basic-demo
+        app.kubernetes.io/instance: demo
+    spec:
+      topologySpreadConstraints:
+        - maxSkew: 1
+          topologyKey: "topology.kubernetes.io/zone"
+          whenUnsatisfiable: ScheduleAnyway
+```

 ## Background
 
 Securing workloads in Kubernetes is an important part of overall cluster security. The overall goal should be to ensure that containers are running with as minimal privileges as possible. This includes avoiding privilege escalation, not running containers with a root user, not giving excessive access to the host network, and using read only file systems wherever possible.
 
+### Gateway API
+
+Gateway API separates listeners, routes, and backend TLS policy across different resources. Polaris checks standard `Gateway` and `HTTPRoute` resources for listener TLS, namespace isolation, host specificity, HTTPS redirects, cross-namespace authorization, and backend TLS. These checks work with conformant implementations such as kgateway.
+
+`httpRouteBackendTLSMissing` also recognizes kgateway's `Backend` and `BackendConfigPolicy` resources. It identifies TLS backends from ports 443 and 8443, Service port names and `appProtocol`, and kgateway static Backend ports. `kgatewayBackendTLSVerificationDisabled` checks the kgateway-specific `insecureSkipVerify` setting. Authentication, authorization, and rate-limiting requirements are organization-specific and should be implemented as custom checks.
+
+Checks marked "Cluster audits only" need related resources that are not available when Polaris evaluates a single admission request. They pass without a resource provider rather than rejecting an object without enough context.
+
 A pod running with the `hostNetwork` attribute enabled will have access to the loopback device, services listening on localhost, and could be used to snoop on network activity of other pods on the same node. There are certain examples where setting `hostNetwork` to true is required, such as deploying a networking plugin like Flannel.
 
 Setting the `hostPort` attribute on a container will ensure that it is accessible on that specific port on each node it is deployed to. Unfortunately when this is specified, it limits where a pod can actually be scheduled in a cluster.
