2.3.3 Scaling a Pod Deployment

To change the number of instances of the same pod that you are running, you can use the kubectl scale deployment command:

$ kubectl scale deployment --replicas=3 hello-world
deployment.apps/hello-world scaled

You can check that the number of pod instances has been scaled appropriately:

$ kubectl get pods
NAME                           READY     STATUS    RESTARTS   AGE
hello-world-5f55779987-tswmg   1/1       Running   0          18s
hello-world-5f55779987-v8w5h   1/1       Running   0          26m
hello-world-5f55779987-wd857   1/1       Running   0          18s
