Releasing a new version of an app deployed as a StatefulSet

We have just covered the scaling of StatefulSets in the previous section by making changes to the .spec.replicas number in the specification. Everything you have learned about sequential and ordered changes to the Pods plays an important role in rolling out a new revision of a StatefulSet object when using the RollingUpdate strategy. There are many similarities between StatefulSets and Deployment objects – we have covered the details of Deployment updates in Chapter 11, Deployment – Deploying Stateless Applications. Making changes to the StatefulSet Pod template (.spec.template) in the specification will also cause the rollout of a new revision for StatefulSet. Usually, you will change the image used by the Pod container to a new version – this is how you perform the release of a new version of an app deployed as StatefulSet.

StatefulSets support two types of update strategies that you define using...
