Kubernetes Namespaces - ResourceQuota - Declarative using YAML¶

Step-01: Create Namespace manifest¶

Important Note: File name starts with 00- so that when creating k8s objects namespace will get created first so it don't throw an error.
```
apiVersion: v1
kind: Namespace
metadata:
  name: dev3
```

Azure Kubernetes Service with Azure DevOps and Terraform¶

Step-02: Create ResourceQuota manifest¶

apiVersion: v1
kind: ResourceQuota
metadata:
  name: ns-resource-quota
  namespace: dev3
spec:
  hard:
    requests.cpu: "1"
    requests.memory: 1Gi
    limits.cpu: "2"
    limits.memory: 2Gi  
    pods: "5"    
    configmaps: "5" 
    persistentvolumeclaims: "5" 
    secrets: "5" 
    services: "5"

Step-03: Create k8s objects & Test¶

# Create All Objects
kubectl apply -f kube-manifests/

# List Pods
kubectl get pods -n dev3

# View Pod Specification (CPU & Memory)
kubectl get pod <pod-name> -o yaml -n dev3

# Get & Describe Limits
kubectl get limits -n dev3
kubectl describe limits default-cpu-mem-limit-range -n dev3

# Get Resource Quota 
kubectl get quota -n dev3
kubectl describe quota ns-resource-quota -n dev3

# List Service
kubectl get svc -n dev3

# Access Application
http://<Public-IP-from-List-Services-Output>/app1/index.html

Step-04: Clean-Up¶

Delete all k8s objects created as part of this section
```
# Delete All
kubectl delete -f kube-manifests/
```
