# Mongo Express
[Mongo Express](https://github.com/mongo-express/mongo-express) is a web-based MongoDB admin interface, written with Node.js and express.
**DISCLAIMER**: This is an unofficial chart not supported by Mongo Express authors.
## TL;DR;
```bash
$ helm repo add cowboysysop https://cowboysysop.github.io/charts/
$ helm install my-release cowboysysop/mongo-express
```
## Introduction
This chart bootstraps a Mongo Express deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
## Prerequisites
- Kubernetes >= 1.24
- Helm >= 3.9
## Installing
Install the chart using:
```bash
$ helm repo add cowboysysop https://cowboysysop.github.io/charts/
$ helm install my-release cowboysysop/mongo-express
```
These commands deploy Mongo Express on the Kubernetes cluster in the default configuration and with the release name `my-release`. The deployment configuration can be customized by specifying the customization parameters with the `helm install` command using the `--values` or `--set` arguments. Find more information in the [configuration section](#configuration) of this document.
## Upgrading
Upgrade the chart deployment using:
```bash
$ helm upgrade my-release cowboysysop/mongo-express
```
The command upgrades the existing `my-release` deployment with the most latest release of the chart.
**TIP**: Use `helm repo update` to update information on available charts in the chart repositories.
### Upgrading to version 5.0.0
The chart is now tested with Kubernetes >= 1.24 and Helm >= 3.9.
Future upgrades may introduce undetected breaking changes if you continue to use older versions.
### Upgrading to version 4.0.0
Some parameters related to port management have been modified:
- Parameter `service.port` has been renamed `service.ports.http`.
- Parameter `service.nodePort` has been renamed `service.nodePorts.http`.
### Upgrading to version 3.0.0
Some parameters related to image management have been modified:
- Registry prefix in `image.repository` parameters is now configured in `image.registry`.
- Parameter `imagePullSecrets` has been renamed `global.imagePullSecrets`.
### Upgrading to version 2.0.0
The chart is no more compatible with Helm 2.
Refer to the [Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/) for more information.
## Uninstalling
Uninstall the `my-release` deployment using:
```bash
$ helm uninstall my-release
```
The command deletes the release named `my-release` and frees all the kubernetes resources associated with the release.
**TIP**: Specify the `--purge` argument to the above command to remove the release from the store and make its name free for later use.

## Setting parameters
Specify the parameters you which to customize using the `--set` argument to the `helm install` command. For instance,
```bash
$ helm install my-release \
--set nameOverride=my-name cowboysysop/mongo-express
```
The above command sets the `nameOverride` to `my-name`.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```bash
$ helm install my-release \
--values values.yaml cowboysysop/mongo-express
```
**TIP**: You can use the default [values.yaml](values.yaml).
