This deployment will be incomplete until you configure Discourse with a resolvable host. To configure Discourse with the URL of your service:

1. Get the discourse URL by running:

  {{- if contains "NodePort" .Values.service.type }}
  export DISCOURSE_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}"):$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "common.names.fullname" . }} -o jsonpath="{.spec.ports[0].nodePort}")
  {{- 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 {{ .Release.Namespace }} -w {{ template "common.names.fullname" . }}'

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

  {{ include "common.utils.secret.getvalue" (dict "secret" $secretName "field" "discourse-password" "context" $) }}

  {{- if (include "discourse.redis.auth.enabled" .) }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $redisSecretName "field" "redis-password" "context" $) }}
  {{- end }}

2. Complete your Discourse deployment by running:

{{- if .Values.postgresql.enabled }}

  helm upgrade --namespace {{ .Release.Namespace }} {{ .Release.Name }} bitnami/{{ .Chart.Name }} \
    --set discourse.host=$DISCOURSE_HOST \
    --set discourse.password=$DISCOURSE_PASSWORD \

    --set postgresql.enabled=false

{{- else -}}

1. Get the Discourse URL by running:

  Discourse URL : http://{{ include "discourse.host" . }}/

{{- if eq .Values.service.type "ClusterIP" }}
  kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ template "common.names.fullname" . }} 80:{{ .Values.service.port }}
{{- end }}

2. Get your Discourse login credentials by running:

  Username: {{ .Values.discourse.username }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $secretName "field" "discourse-password" "context" $) }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $postgresqlSecretName "field" "postgresql-password" "context" $) }}
  {{- if (include "discourse.redis.auth.enabled" .) }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $redisSecretName "field" "redis-password" "context" $) }}
  {{- end }}

{{- end }}
