Services for Network Access
Expose your applications inside and outside the cluster using various Kubernetes Service types.
What is a Kubernetes Service?
In Kubernetes, Pods are the smallest deployable units. They are designed to be ephemeral, meaning they can be created, deleted, or replaced at any time, often receiving new IP addresses.
This dynamic nature makes it hard for other applications to reliably find and communicate with them. This is where Services come in!
Providing Stable Network Access
A Kubernetes Service acts as a stable network endpoint for a set of Pods. Think of it as a permanent address that doesn't change, even if the Pods behind it do.
- Services provide a consistent IP address and DNS name.
- They can load balance traffic across multiple Pods.
- They ensure continuous availability as Pods scale or restart.
