Namespace

Namespace in Kubernetes is basically an abstraction to divide cluster into sub-virtual cluster that isolate from each other. We can group resources based on department on team with namespace by creating namespace and then assign any kubernetes objects to it.

Namespace Manifest File

namespace.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: prod
  labels:
    app: prod

After make the manifest file, we apply the manifest to create namespace

kubectl apply -f namespace.yaml

Then check the namespace

# Get Namespace
kubectl get namespace

# Gheck object that saved in namespace
kubectl api-resources --namespaced=true

We also can see what resource is in the namespace

# Get Pod
kubectl get pods -n [NAMESPACE]

# Get Service
kubectl get service -n [SERVICE_NAME]

# Get all Resource
kubectl get all -n [NAMESPACE]
