GKE security features

The contents of your container image, the container runtime, the cluster network, and access to the cluster API server all play a role in protecting workloads in GKE. Let us understand a few security features in GKE.

Namespaces

In Kubernetes, namespaces are used to separate groups of resources in a cluster. Resources within a namespace must have unique names, but this requirement doesn’t apply across namespaces. It’s important to note that namespace-based scoping only applies to resources that are specific to a namespace, such as Deployments and Services, and doesn’t apply to objects that are used across the entire cluster, such as Nodes, StorageClass, and PersistentVolume.

Namespaces in Kubernetes are intended for situations where there are multiple users spread across different teams or projects. If your cluster only has a small number of users, you may not need to worry about namespaces.
