Creating Deployment

Deployment is a controller for pods, you create a template for a pod and run X replicas of the pod. In a deployment all the replicas of the pods are stateless, meaning the names of the pod are dynamic.

Modify the below manifest to include the pod spec from the pod.yaml:

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: veri-deployment
  labels:
    app: http-echo
spec:
  replicas: <?>
  selector:
    matchLabels:
      app: http-echo
  template:
    metadata:
      labels:
        app: http-echo #needs to match with selector for Deployment to find pod!
    spec:
      <your-code-comes-here>

Again deploy the manifest and use get/describe to view the status of the deployment:

kubectl get deployments
kubectl get deployment veri-deployment
kubectl describe deployment veri-deployment

You can refer to official docs for more examples: https://kubernetes.io/docs/concepts/workloads/deployments/

If you're struggling with yaml or short on time, you can get the completed manifest under here

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: veri-deployment
  labels:
    app: http-echo
spec:
  replicas: 1
  selector:
    matchLabels:
      app: http-echo
  template:
    metadata:
      labels:
        app: http-echo #needs to match with selector for Deployment to find pod!
    spec:
      containers:
      - name: http-echo
        env:
        - name: ECHO_TEXT
          value: "Wohoo"
        image: verifa/http-echo:latest
        ports:
        - containerPort: 5678
