Containers Orchestrator hands-on lab with Kubernetes

Create and deploy into Kubernetes Namspaces

Kubernetes provides namespaces as a way to create isolated environments within a cluster (e.g. dev,test,prod)

https://github.com/lastcoolnameleft/demos/blob/master/k8s-lab/k8s-create-namespaces.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: test
  labels:
    name: test
---
apiVersion: v1
kind: Namespace
metadata:
  name: prod
  labels:
    name: prod

Create a test and prod namespace deployment using the kubectl create command:

kubectl create -f https://raw.githubusercontent.com/lastcoolnameleft/demos/master/k8s-lab/k8s-create-namespaces.yaml

Use the UI or command line to verify the available namespaces now include test and prod:

kubectl get namespaces

Deploy the demo application into the test namespace

• Get a list of the current contexts
  • Context is a tuple of {Cluster, User, Namespace}
• Create a context named test and bind it to the test namespace
• Set the current context to test
• Show the current context again and note that test is tagged as CURRENT
• Deploy the application into the test namespace

kubectl config get-contexts
kubectl config set-context test --cluster=$RESOURCE_GROUP --user=$USER --namespace=test 
kubectl config use-context test
kubectl config get-contexts
