A declarative way of maintaining the desired state.

Continuing my example from the last blog

--- # Pod deployment
apiVersion: apps/v1
kind: Deployment
metadata:
 name: go-server-deployment
spec:
 replicas: 2
 selector:
 matchLabels:
 app: my-go-server
 template:
 metadata:
 labels:
 app: my-go-server
 spec:
 containers:
 - name: go-server
 image: samarthya/epserver:2.0
 resources:
 limits:
 memory: "256Mi"
 cpu: "1024m"
 env:
 - name: SERVERPORT
 value: "9090"
 ports:
 - containerPort: 9090
# Reference - https://kubernetes.io/docs/concepts/workloads/controllers/deployment/

In my deployment, I have two replicas configured, which can be increased to three using the command like the one below.
