public class Deployment
extends Resource
implements IPodTemplate
    A Deployment provides declarative updates for Pods and ReplicaSets.

    You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new ReplicaSets, or to remove existing Deployments and adopt all their resources with new Deployments.

    Note: Do not manage ReplicaSets owned by a Deployment. Consider opening an issue in the main Kubernetes repository if your use case is not covered below.

    Use Case

    The following are typical use cases for Deployments:

    • Create a Deployment to rollout a ReplicaSet. The ReplicaSet creates Pods in the background. Check the status of the rollout to see if it succeeds or not.
    • Declare the new state of the Pods by updating the PodTemplateSpec of the Deployment. A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. Each new ReplicaSet updates the revision of the Deployment.
    • Rollback to an earlier Deployment revision if the current state of the Deployment is not stable. Each rollback updates the revision of the Deployment.
    • Scale up the Deployment to facilitate more load.
    • Pause the Deployment to apply multiple fixes to its PodTemplateSpec and then resume it to start a new rollout.
    • Use the status of the Deployment as an indicator that a rollout has stuck.
    • Clean up older ReplicaSets that you don't need anymore.
