Deploying a new application version

In the previous chapter, we deployed an application using the nginx v1.18.0 Docker image. In this section, let's update it to nginx v1.19.0:

To update the nginx Docker image tag, run the following command:

$ kubectl set image deployment nginx nginx=nginx:1.19.0 \
 --record
deployment.apps/nginx image updated
$ kubectl rollout status deployment nginx
deployment "nginx" successfully rolled out
$ kubectl get deployment nginx
NAME    READY   UP-TO-DATE   AVAILABLE   AGE
