## Overview

This is a Helm chart for deploying Mongo Express with MongoDB on Kubernetes. The main workflow is an operator installing the chart, which provisions the web and database workloads and exposes the web interface for browser access. The chart also configures database credentials and persistent storage. The README and file tree establish the intended resources and settings, but source excerpts were unavailable, so detailed manifest wiring is not inferred.

Main entry points: [`Chart.yaml`](https://github.com/mathesh-me/helm-mongo-admin/blob/main/Chart.yaml) (Chart definition), [`templates/db-depl.yaml`](https://github.com/mathesh-me/helm-mongo-admin/blob/main/templates/db-depl.yaml) (MongoDB workload), [`templates/pvc.yaml`](https://github.com/mathesh-me/helm-mongo-admin/blob/main/templates/pvc.yaml) (Volume claim), [`templates/web-depl.yaml`](https://github.com/mathesh-me/helm-mongo-admin/blob/main/templates/web-depl.yaml) (Mongo Express workload)
