### ERROR: You enabled external access to MongoDB&reg; nodes without specifying  ###
###   the array of load balancer IPs for MongoDB&reg; nodes.                     ###
####################################################################################

This deployment will be incomplete until you configure the array of load balancer
IPs for MongoDB&reg; nodes. To complete your deployment follow the steps below:

1. Wait for the load balancer IPs (it may take a few minutes for them to be available):

    kubectl get svc --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ template "mongodb.name" . }},app.kubernetes.io/instance={{ .Release.Name }},app.kubernetes.io/component=mongodb" -w

2. Obtain the load balancer IPs and upgrade your chart:

    {{- range $e, $i := until $replicaCount }}
    LOAD_BALANCER_IP_{{ add $i 1 }}="$(kubectl get svc --namespace {{ $releaseNamespace }} {{ $fullname }}-{{ $i }}-external -o jsonpath='{.status.loadBalancer.ingress[0].ip}')"
    {{- end }}

3. Upgrade you chart:

    helm upgrade --namespace {{ .Release.Namespace }} {{ .Release.Name }} bitnami/{{ .Chart.Name }} \
      --set mongodb.replicaCount={{ $replicaCount }} \
      --set mongodb.externalAccess.enabled=true \
      {{- range $i, $e := until $replicaCount }}
      --set mongodb.externalAccess.service.loadBalancerIPs[{{ $i }}]=$LOAD_BALANCER_IP_{{ add $i 1 }} \
      {{- end }}
      --set mongodb.externalAccess.service.type=LoadBalancer

{{- else }}

{{- if and (or (and (eq .Values.architecture "standalone") (or (eq .Values.service.type "LoadBalancer") (eq .Values.service.type "NodePort"))) (and (eq .Values.architecture "replicaset") .Values.externalAccess.enabled)) (not .Values.auth.enabled) }}
-------------------------------------------------------------------------------
 WARNING

    By not enabling "mongodb.auth.enabled" you have most likely exposed the
    MongoDB&reg; service externally without any authentication mechanism.

    For security reasons, we strongly suggest that you enable authentiation
    setting the "mongodb.auth.enabled" parameter to "true".

-------------------------------------------------------------------------------
{{- end }}

** Please be patient while the chart is being deployed **

MongoDB&reg; can be accessed on the following DNS name(s) and ports from within your cluster:

{{- if eq .Values.architecture "replicaset" }}
{{ join "\n" $mongoList | nindent 4 }}
{{- else }}

    {{ $fullname }}.{{ $releaseNamespace }}.svc.{{ .Values.clusterDomain }}

{{- end }}

{{- if .Values.auth.enabled }}

To get the root password run:

    export MONGODB_ROOT_PASSWORD=$(kubectl get secret --namespace {{ template "mongodb.namespace" . }} {{ template "mongodb.secretName" . }} -o jsonpath="{.data.mongodb-root-password}" | base64 --decode)

{{- end }}
{{- $customUsers := include "mongodb.customUsers" . -}}
{{- $customDatabases := include "mongodb.customDatabases" . -}}
{{- if and (not (empty $customUsers)) (not (empty $customDatabases)) }}
{{- $customUsersList := splitList "," $customUsers }}
{{- range $index, $user := $customUsersList }}

To get the password for "{{ $user }}" run:

    export MONGODB_PASSWORD=$(kubectl get secret --namespace {{ include "mongodb.namespace" $ }} {{ include "mongodb.secretName" $ }} -o jsonpath="{.data.mongodb-passwords}" | base64 --decode | awk -F',' '{print ${{ add 1 $index }}}')

{{- end }}
{{- end }}

To connect to your database, create a MongoDB&reg; client container:

    kubectl run --namespace {{ template "mongodb.namespace" . }} {{ template "mongodb.fullname" . }}-client --rm --tty -i --restart='Never' --env="MONGODB_ROOT_PASSWORD=$MONGODB_ROOT_PASSWORD" --image {{ template "mongodb.image" . }} --command -- bash

Then, run the following command:

    {{- if eq .Values.architecture "replicaset" }}
    mongo admin --host "{{ join "," $mongoList }}" {{- if .Values.auth.enabled }} --authenticationDatabase admin -u root -p $MONGODB_ROOT_PASSWORD{{- end }}
    {{- else }}
    mongo admin --host "{{ template "mongodb.fullname" . }}" {{- if .Values.auth.enabled }} --authenticationDatabase admin -u root -p $MONGODB_ROOT_PASSWORD{{- end }}
    {{- end }}

{{- if and (eq .Values.architecture "replicaset") .Values.externalAccess.enabled }}

To connect to your database nodes from outside, you need to add both primary and secondary nodes hostnames/IPs to your Mongo client. To obtain them, follow the instructions below:

{{- if eq "NodePort" .Values.externalAccess.service.type }}
{{- if .Values.externalAccess.service.domain }}

    MongoDB&reg; nodes domain: Use your provided hostname to reach MongoDB&reg; nodes, {{ .Values.externalAccess.service.domain }}

{{- else }}

    MongoDB&reg; nodes domain: you can reach MongoDB&reg; nodes on any of the K8s nodes external IPs.

        kubectl get nodes -o wide

{{- end }}

    MongoDB&reg; nodes port: You will have a different node port for each MongoDB&reg; node. You can get the list of configured node ports using the command below:

        echo "$(kubectl get svc --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ template "mongodb.name" . }},app.kubernetes.io/instance={{ .Release.Name }},app.kubernetes.io/component=mongodb,pod" -o jsonpath='{.items[*].spec.ports[0].nodePort}' | tr ' ' '\n')"

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

  NOTE: It may take a few minutes for the LoadBalancer IPs to be available.
        Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ template "mongodb.name" . }},app.kubernetes.io/instance={{ .Release.Name }},app.kubernetes.io/component=mongodb,pod" -w'

    MongoDB&reg; nodes domain: You will have a different external IP for each MongoDB&reg; node. You can get the list of external IPs using the command below:

        echo "$(kubectl get svc --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ template "mongodb.name" . }},app.kubernetes.io/instance={{ .Release.Name }},app.kubernetes.io/component=mongodb,pod" -o jsonpath='{.items[*].status.loadBalancer.ingress[0].ip}' | tr ' ' '\n')"

    MongoDB&reg; nodes port: {{ .Values.externalAccess.service.port }}

{{- end }}

{{- else if eq .Values.architecture "standalone" }}

To connect to your database from outside the cluster execute the following commands:

{{- if contains "NodePort" .Values.service.type }}

    export NODE_IP=$(kubectl get nodes --namespace {{ template "mongodb.namespace" . }} -o jsonpath="{.items[0].status.addresses[0].address}")
    export NODE_PORT=$(kubectl get --namespace {{ template "mongodb.namespace" . }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "mongodb.fullname" . }})
    mongo --host $NODE_IP --port $NODE_PORT {{- if .Values.auth.enabled }} --authenticationDatabase admin -p $MONGODB_ROOT_PASSWORD{{- end }}

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

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace {{ template "mongodb.namespace" . }} -w {{ template "mongodb.fullname" . }}'

    export SERVICE_IP=$(kubectl get svc --namespace {{ template "mongodb.namespace" . }} {{ template "mongodb.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
    mongo --host $SERVICE_IP --port {{ $portNumber }} {{- if .Values.auth.enabled }} --authenticationDatabase admin -p $MONGODB_ROOT_PASSWORD{{- end }}

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

    kubectl port-forward --namespace {{ template "mongodb.namespace" . }} svc/{{ template "mongodb.fullname" . }} {{ $portNumber }}:{{ $portNumber }} &
    mongo --host 127.0.0.1 {{- if .Values.auth.enabled }} --authenticationDatabase admin -p $MONGODB_ROOT_PASSWORD{{- end }}

{{- end }}
{{- end }}
{{- end }}

{{- if .Values.metrics.enabled }}

To access the MongoDB&reg; Prometheus metrics, get the MongoDB&reg; Prometheus URL by running:

    kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ include "mongodb.fullname" . }}-metrics {{ .Values.metrics.service.port }}:{{ .Values.metrics.service.port }} &
    echo "Prometheus Metrics URL: http://127.0.0.1:{{ .Values.metrics.service.port }}/metrics"

Then, open the obtained URL in a browser.
