This Helm chart is deprecated

Given the `stable` deprecation timeline (https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained Helm chart is now located at bitnami/charts (https://github.com/bitnami/charts/).

The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)

```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/<chart>           # Helm 3
$ helm install --name my-release bitnami/<chart>    # Helm 2
```

To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute

```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm upgrade my-release bitnami/<chart>
```

Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in this issue (https://github.com/helm/charts/issues/20969) created as a common place for discussion.

{{- if or .Values.mariadb.enabled .Values.externalDatabase.host -}}
** Please be patient while the chart is being deployed **
{{- if and .Values.ingress.enabled (ne .Values.service.type "ClusterIP") }}
** Notice : Usually with ingress the service.type should be set to ClusterIP, which is not the case to this deployment! **
{{- end }}

1. Access you Moodle instance with:

{{- if .Values.ingress.enabled }}
  {{ if .Values.ingress.tls }}
    {{- range .Values.ingress.hosts }}
    - https://{{ . }}
    {{- end }}
  {{- else }}
    {{- range .Values.ingress.hosts }}
    - http://{{ . }}
    {{- end }}
  {{- end }}
{{- else if contains "NodePort" .Values.service.type }}
  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "moodle.fullname" . }})
  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
  echo "Moodle URL: http://$NODE_IP:$NODE_PORT/"

{{- else if contains "LoadBalancer" .Values.service.type }}

** Please ensure an external IP is associated to the {{ template "moodle.fullname" . }} service before proceeding **
** Watch the status using: kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "moodle.fullname" . }} **

  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "moodle.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")

{{- $port:=.Values.service.port | toString }}
  echo "Moodle URL: http://$SERVICE_IP{{- if ne $port "80" }}:{{ .Values.service.port }}{{ end }}/"

{{- else if contains "ClusterIP"  .Values.service.type }}

  kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ template "moodle.fullname" . }} 8080:{{ .Values.service.port }}
  echo "Moodle URL: http://127.0.0.1:8080/"

{{- end }}

2. Login with the following credentials

  echo Username: {{ .Values.moodleUsername }}
  echo Password: $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "moodle.fullname" . }} -o jsonpath="{.data.moodle-password}" | base64 --decode)

{{- else -}}

This deployment will be incomplete until you configure Moodle with a resolvable database
host. To configure Moodle to use and external database host:


1. Complete your Moodle deployment by running:

  helm upgrade {{ .Release.Name }} --set service.type={{ .Values.service.type }},mariadb.enabled=false,externalDatabase.host=YOUR_EXTERNAL_DATABASE_HOST stable/moodle

{{- end }}

WARNING: Rolling tag detected ({{ .Values.image.repository }}:{{ .Values.image.tag }}), please note that it is strongly recommended to avoid using rolling tags in a production environment.
