Deploy NGINX on the Kubernetes Cluster

Deploy NGINX on the Kubernetes Cluster

From your master node kubectl create an nginx deployment:

kubectl create deployment nginx --image=nginx

1. This creates a deployment called nginx. kubectl get deployments lists all available deployments:

   kubectl get deployments
   

2. Use kubectl describe deployment nginx to view more information:

1. Make the NGINX container accessible via the internet:

   kubectl create service nodeport nginx --tcp=80:80
   

   This creates a public facing service on the host for the NGINX deployment. Because this is a nodeport deployment, kubernetes will assign this service a port on the host machine in the 32000+ range.
   Try to get the current services:

   root@kube-master:~# kubectl get svc
   NAME         TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
   kubernetes   ClusterIP   10.96.0.1     <none>        443/TCP        5h
   nginx        NodePort    10.98.24.29   <none>        80:32555/TCP   52s
   

2. Verify that the NGINX deployment is successful by using curl on the slave node:

   root@kube-master:~# curl kube-worker-1:32555
   

   The output will show the unrendered “Welcome to nginx!” page HTML.
