deployment strategy of sentinel to Recreate

[raviranjanelastisys]

Do you have the option to change the deployment strategy of sentinel to Recreate instead of default Rollingupdate ? I tried but i am facing below error .

@raviranjanelastisys where did you try to change it? If you are trying to change in the Deployment resources managed by the operator, that's NOT the right thing to do. Its ideally a code change in the operator, and would need to do something like this.

But I definitely would want to hear the use-case.

@samof76 That would be great if you add in the operator , as i want to use the Podantiaffnity with requiredDuringSchedulingIgnoredDuringExecution and new the pods become pending state while rollingupdate as i have only 3 workers node and i don't want to increase the worker nodes !! So, i want this option for sentinel deployment

@raviranjanelastisys please use topologySpreadConstraints instead. They give you better distribution of pods.

Thanks @samof76 But seems like topologySpreadConstraints is not supported in your operator .
