[Question] Inconsistency regarding the count of Env Injector installed in the cluster

[lshi18]

I'd like to ask a question concerning the inconsistency regarding the count of Env Injector installed in the cluster. Why is it that in the Requiement, it says

Note: You should at most have only one Env Injector installment in your cluster, because multiple instances of the Env Injector mutating webhook might compete and fail when a new pod (that needs environment injection) is created.

but at the same time, the default value for the env_injector.replicaCount in the chart is set to 2?

Using the default value of 2 seems to have led us into this issue.

Thanks

The replicas fall behind the same Service resource because replicas are part of a Deployment. The documentation is advising not to have multiple Deployments of AKV2K8S env-injector (one might do this to have a separation of privileges by deploying different env-injectors to different namespaces, much the way Gitlab advises to deploy their Gitlab Agent, however this setup is not one that can be supported because the cluster can have at most one AKV2K8S MutatingWebhookConfiguration resource.)
