Mac – create a one container pod and get shell to it

Steps to create a pod with nginx container and get shell to it:

1. Create config file shell-demo.yaml
   

   apiVersion: v1
   kind: Pod
   metadata:
     name: shell-demo
   spec:
     volumes:
     - name: shared-data
       emptyDir: {}
     containers:
     - name: nginx
       image: nginx
       volumeMounts:
       - name: shared-data
         mountPath: /usr/share/nginx/html
     hostNetwork: true
     dnsPolicy: Default

2. Create the pod
   kubectl apply -f shell-demo.yaml
3. Get a shell to the running container (container name will be needed in case more than one containers in pod)
   kubectl exec --stdin --tty shell-demo -- /bin/bash
4. Create a root page for nginx (in shell window)
   echo 'Hello shell demo' > /usr/share/nginx/html/index.html
5. Install curl and test the site
   apt-get update
apt-get install curl
curl http://localhost/
   The output should show:
   Hello shell demo
