Cluster Chart : Mongo

This helm chart is used to deploy MongoDB instances managed by the official mongodb operator.

This chart is part of the cluster-xxx startx helm chart series that doesn’t necessarily deploy pods but rather represent a cluster configuration state orchestrated by gitops tools like ArgoCD.
