What we cover
Master Kubernetes networking — Services, Ingress, DNS, CNI plugins, and Network Policies that control how traffic flows inside and into your cluster.
Written guides that show you how to apply this concept in real projects.
Key words used in this concept — explained simply, no jargon.
A Kubernetes mechanism for partitioning cluster resources into isolated virtual segments. Namespaces allow multiple teams, projects, or environments to share the same physical cluster while maintaining logical separation of workloads, access controls, and resource quotas. They do not provide network isolation by themselves — that requires Network Policies.
An API object that manages external HTTP and HTTPS access to services inside a cluster. Ingress sits in front of multiple services and acts as a smart router — directing traffic based on hostnames, URL paths, or headers without exposing each service directly to the internet.
