1. Let's try to create several Pods with the previous labels to distinguish different projects, environments, and tiers, as follows:

YAML Filename	Pod Image	Project	Environment	Tier
pilot-dev.yaml	nginx	pilot	develop	frontend
pilot-dev.yaml	memcached			cache
pilot-prod.yaml	nginx		production	frontend
pilot-prod.yaml	memcached			cache
poc-dev.yaml	httpd	poc	develop	frontend
poc-dev.yaml	memcached			cache

2. For convenience, we will prepare three YAML files that contain two Pods each, with a YAML separator --- between Pods:

• pilot-dev.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: pilot.dev.nginx
  labels:
    project: pilot
    environment: develop
    tier: frontend
spec:
  containers:
    - name: nginx
      image: nginx
---
apiVersion: v1
kind: Pod
metadata:
  name: pilot.dev.memcached
  labels:
    project: pilot
    environment: develop
    tier: cache
spec:
  containers:
    - name: memcached
      image: memcached

• pilot-prod.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: pilot.prod.nginx
  labels:
    project: pilot
    environment: production
    tier: frontend
spec:
  containers:
    - name : nginx
      image: nginx
---
apiVersion: v1
kind: Pod
metadata:
  name: pilot.prod.memcached
  labels:
    project: pilot
    environment: production
    tier: cache
spec:
  containers:
    - name: memcached
      image: memcached

• poc-dev.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: poc.dev.httpd
  labels:
    project: poc
    environment: develop
    tier: frontend
spec:
  containers:
    - name: httpd
      image: httpd
---
apiVersion: v1
kind: Pod
metadata:
  name: poc.dev.memcached
  labels:
    project: poc
    environment: develop
    tier: cache
spec:
  containers:
    - name: memcached
      image: memcached
