The Deployment creates three replicated Pods, indicated by the .spec.replicas field. It does not wait for the 5 replicas of nginx:1.14.2 to be created The solution is pretty easy and straightforward. Deployment also ensures that only a certain number of Pods are created above the desired number of Pods. More specifically, setting this field to zero means that all old ReplicaSets with 0 replicas will be cleaned up. So, for example, if you want to scale a deployment called "example-app," you can execute: kubectl scale deployment/example-app --replicas=4. What was the significance of the word "ordinary" in "lords of appeal in ordinary"?

The kubectl scale command can scale several resources at once when you supply more than one name as arguments. Existing ReplicaSets are not orphaned, and a new ReplicaSet is not created, but note that the For example, with a Deployment that was created: Get the rollout status to verify that the existing ReplicaSet has not changed: You can make as many updates as you wish, for example, update the resources that will be used: The initial state of the Deployment prior to pausing its rollout will continue its function, but new updates to For additional examples on using the horizontal pod autoscaler, see HorizontalPodAutoscaler Walkthrough. Ensure that the 10 replicas in your Deployment are running. managing resources. The configuration of each Deployment revision is stored in its ReplicaSets; therefore, once an old ReplicaSet is deleted, you lose the ability to rollback to that revision of Deployment. returns a non-zero exit code if the Deployment has exceeded the progression deadline. Downtimeless Restarts With Rollouts it ensures that at least 75% of the desired number of Pods are up (25% max unavailable). number of seconds the Deployment controller waits before indicating (in the Deployment status) that the type: Available with status: "True" means that your Deployment has minimum availability. JobManager REST UI Service. down further, followed by scaling up the new ReplicaSet, ensuring that the total number of Pods available ReplicaSets (ReplicaSets with Pods) in order to mitigate risk.
