Updating deployment imagesΒΆ

In the next sections we are going to see on how to make a realistic deployments.

  • First, we'll revert the changes in the deployment to use the multi-client
  • We are going to update and push a new image to docker hub
  • Get the deployment to recreate our pods with the latest verision of the image

So, we are changing the client-deployment.yaml file back to:

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

$ kubectl apply -f client-deployment.yaml
deployment.apps/client-deployment configured
$ kubectl get deployment
NAME                READY   UP-TO-DATE   AVAILABLE   AGE
client-deployment   1/1     1            1           20m
$ kubectl get pods
NAME                                 READY   STATUS        RESTARTS   AGE
client-deployment-69f476d99b-s4trm   0/1     Terminating   0          10m
client-deployment-7bf8c9b5c5-ptj4h   1/1     Running       0          11s

And check that we can still access it:

$ minikube ip
192.168.99.101
