Types of Kubernetes Policies
Network Policy
Network policies in Kubernetes allow you to specify how groups of pods are allowed to communicate with each other and other network endpoints. You can use network policies to isolate pods or allow specific inbound or outbound traffic for pods. Network policies are implemented using a controller that creates iptables rules on the nodes in the cluster.
Pod Security Policy
Pod security policies allow you to specify security constraints that apply to a pod’s containers. You can use pod security policies to specify things like allowed capabilities, allowed privileged operations, and required volume types.
Resource Quotas
Resource quotas allow you to limit the number of resources (such as CPU, memory, and storage) that are consumed by pods in a namespace. You can use resource quotas to prevent one set of pods from using all of the resources in a namespace, leaving none for other pods.
Limit Ranges
Limit ranges allow you to specify the minimum and maximum limits for resources (such as CPU and memory) that can be allocated to pods in a namespace. You can use limit ranges to ensure that pods are not allocated more resources than they need, or to prevent a single pod from consuming all of the resources in a namespace.
Kubernetes Policies
Pre-requisite: Kubernetes
In this article, we will be discussing Kubernetes policies, a key feature in the Kubernetes platform that allows administrators to enforce rules and restrictions on the use and management of resources within a cluster. We will cover the basics of Kubernetes policies, including their types and how they are implemented and managed, as well as delve into some of the more advanced features and use cases for Kubernetes policies.
