  apiVersion: v1    <-- K8s is extensible - we may add in our own custom objects
  kind: Pod         <-- the type of object we want to create
  metadata:         <-- config options for the object we are about to create
    name: posts     <-- when the pod is created, give it a name of "posts"
  spec:             <-- The exact attributes we want to apply to the object we are about to create 
    containers:     <-- An array. We can create many containers in a single pod
      - name: posts   <-- An array entity. One array entry. Make a container with a name of 'posts'
        image: docker.io/rayalevinson/posts:0.0.1    <-- The exact image we want to use

By default if version is not specified, docker adds :latest as version.

If version is not specified or :latest is specified, k8s will reach out the Docker Hub and will try to find and image listed in Docker Hub.

When version like 0.0.1 is specified, k8s will search for the image on the local machine first.

Run the yaml file
  cd ..
  cd infra/k8s
  kubectl apply -f posts.yaml  

Result: pod/posts created
