Mastering Kubernetes Services: Types, Use-cases, and Security Practices
One of the core features of Kubernetes is its Service concept, which provides a way to expose applications running in a cluster to other services or users.
In this article, we will dive deeper into Kubernetes Services and their types, use cases, examples, and security practices.
What is a Kubernetes Service?
A Kubernetes Service is an abstraction that defines a logical set of pods and a policy by which to access them. Services enable a loose coupling between dependent applications by providing a stable IP address and DNS name for a set of pods, even if the pods are dynamically scaled or replaced.
A Service consists of a selector and a set of endpoints. The selector is used to match a set of pods, and the endpoints are the IP addresses of the pods that match the selector.
Types of Kubernetes Services:
Kubernetes Services come in four types: ClusterIP, LoadBalancer, and NodePort
ClusterIP
A ClusterIP Service provides a stable IP address and DNS name for pods within a cluster. This type of Service is the default, and it is used for internal…
