# Moodle
[Moodle](https://www.moodle.org) Moodle is a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create personalised learning environments
## TL;DR;
```console
$ helm install .
```
## Introduction
This chart bootstraps a [Moodle](https://github.com/bitnami/bitnami-docker-moodle) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
It also packages the [Bitnami MariaDB chart](https://github.com/kubernetes/charts/tree/master/stable/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the Moodle application.
## Prerequisites
- Kubernetes 1.4+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install --name my-release ./moodle
```
The command deploys Moodle on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
## Configuration
The following tables lists the configurable parameters of the Moodle chart and their default values.
| Parameter | Description | Default |
|------------------------------------|----------------------------------------|---------------------------------------------|
| `image` | Moodle image | `bitnami/moodle:{VERSION}` |
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
| `moodleUsername` | User of the application | `user` |
| `moodlePassword` | Application password | _random 10 character alphanumeric string_ |
| `moodleEmail` | Admin email | `user@example.com` |
| `smtpHost` | SMTP host | `nil` |
| `smtpPort` | SMTP port | `nil` |
| `smtpProtocol` | SMTP Protocol | `nil` |
| `smtpUser` | SMTP user | `nil` |
| `smtpPassword` | SMTP password | `nil` |
| `serviceType` | Kubernetes Service type | `LoadBalancer` |
| `resources` | CPU/Memory resource requests/limits | Memory: `512Mi`, CPU: `300m` |
| `persistence.enabled` | Enable persistence using PVC | `true` |
| `persistence.apache.storageClass` | PVC Storage Class for Apache volume | `nil` (uses alpha storage class annotation) |
| `persistence.apache.accessMode` | PVC Access Mode for Apache volume | `ReadWriteOnce` |
| `persistence.apache.size` | PVC Storage Request for Apache volume | `1Gi` |
| `persistence.moodle.storageClass` | PVC Storage Class for Moodle volume | `nil` (uses alpha storage class annotation) |
| `persistence.moodle.accessMode` | PVC Access Mode for Moodle volume | `ReadWriteOnce` |
| `persistence.moodle.size` | PVC Storage Request for Moodle volume | `8Gi` |
| `mariadb.mariadbRootPassword` | MariaDB admin password | `nil` |
| `mariadb.persistence.enabled` | Enable MariaDB persistence using PVC | `true` |
| `mariadb.persistence.storageClass` | PVC Storage Class for MariaDB volume | `generic` |
| `mariadb.persistence.accessMode` | PVC Access Mode for MariaDB volume | `ReadWriteOnce` |
| `mariadb.persistence.size` | PVC Storage Request for MariaDB volume | `8Gi` |
The above parameters map to the env variables defined in [bitnami/moodle](http://github.com/bitnami/bitnami-docker-moodle). For more information please refer to the [bitnami/moodle](http://github.com/bitnami/bitnami-docker-moodle) image documentation.
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install --name my-release \
--set moodleUsername=admin,moodlePassword=password,mariadb.mariadbRootPassword=secretpassword \
stable/moodle
```
The above command sets the Moodle administrator account username and password to `admin` and `password` respectively. Additionally it sets the MariaDB `root` user password to `secretpassword`.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```console
$ helm install --name my-release -f values.yaml stable/moodle
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Persistence
The [Bitnami Moodle](https://github.com/bitnami/bitnami-docker-moodle) image stores the Moodle data and configurations at the `/bitnami/moodle` and `/bitnami/apache` paths of the container.
Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Configuration](#configuration) section to configure the PVC or to disable persistence.
