Upgrading application

Kubernetes update strategies

Kubernetes provides two strategies to update applications managed by statefulset controllers:

Rolling update

The pods will be upgraded one by one until all pods run containers with the updated template. The upgrade is managed by Kubernetes and the user has limited control during the upgrade process, after having modified the template. This is the default upgrade strategy in Kubernetes.

To perform a canary or multi-phase upgrade, a partition can be defined on the cluster and Kubernetes will upgrade just the nodes in that partition.

The default implementation is based on RollingUpdate strategy with no partition defined.

OnDelete strategy

In this strategy users select the pod to upgrade by deleting it, and Kubernetes will replace it by creating a new pod based on the updated template. To select this strategy the following should be replaced with the current implementation of updateStrategy in the statefulset spec:

    type: OnDelete
