Deployment configuration files¶

In order to create the deployment configuration file, we'll create a new client-deployment.yml file :

apiVersion: apps/v1
kind: Deployment
metadata:
  name: client-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: web
  template:
    metadata:
      labels:
        component: web
    spec:
      containers:
        - name: client
          image: deiveris/multi-client
          ports:
            - containerPort: 3000

The template describes the pod to be created. The replicas describes the number of pods to make. The selector describes a handle for the deployment to find the pod after it's created.
