I am unable to patch my statefulset to use a RollingUpdate strategy.
(Encountered while working through the "StatefulSet Basics" tutorial here)
$ kubectl patch statefulset web -p '{"spec":{"strategy":{"type":"RollingUpdate"}}}'
statefulset "web" not patchedI wish kubectl patch would return more info as to the reason the statefulset could not be patched.
kubectl edit tells me...
found invalid field updateStrategy for v1beta1.StatefulSetSpec
But I am not sure I put the key and value in the proper place to be sure this is the same issue patch is encountering.
How do tell my statefulset to use a RollingUpdate strategy?
To reproduce this issue just follow the Kubernetes tutorial here: https://kubernetes.io/docs/tutorials/stateful-application/basic-stateful-set/
Better to apply changes on your yaml file directly.
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: nginx-sts
spec:
serviceName: "nginx-headless"
replicas: 3
#podManagementPolicy: Parallel
selector:
matchLabels:
run: nginx-sts-demo
updateStrategy:
rollingUpdate:
partition: 0 #for full partition update
type: RollingUpdate
