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

1. Get the Ghost URL by running:

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

  export APP_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")

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

  {{- end }}

  {{ include "common.utils.secret.getvalue" (dict "secret" $ghostSecretName "field" $ghostPasswordKey "context" $) }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $databaseSecretName "field" "mysql-root-password" "context" $) }}
  {{ include "common.utils.secret.getvalue" (dict "secret" $databaseSecretName "field" "mysql-password" "context" $) }}

2. Complete your Ghost deployment by running:

{{- if .Values.mysql.enabled }}

  helm upgrade --namespace {{ .Release.Namespace }} {{ .Release.Name }} my-repo/{{ .Chart.Name }} \
    --set service.type={{ .Values.service.type }},ghostHost=$APP_HOST,ghostPassword=$GHOST_PASSWORD,mysql.auth.rootPassword=$MYSQL_ROOT_PASSWORD,mysql.auth.password=$MYSQL_PASSWORD{{- if .Values.global }}{{- if .Values.global.imagePullSecrets }},global.imagePullSecrets={{ .Values.global.imagePullSecrets }}{{- end }}{{- end }}

1. Get the Ghost URL and associate its hostname to your cluster external IP:

   export CLUSTER_IP=$(minikube ip) # On Minikube. Use: `kubectl cluster-info` on others K8s clusters
   echo "Ghost URL: http{{ if .Values.ingress.tls }}s{{ end }}://{{ .Values.ingress.hostname }}"
   echo "$CLUSTER_IP  {{ .Values.ingress.hostname }}" | sudo tee -a /etc/hosts

{{- else }}

1. Get the Ghost URL by running:

{{- if eq .Values.service.type "ClusterIP" }}

  echo Blog URL  : http://127.0.0.1:{{ default "80" (coalesce .Values.service.ports.http .Values.service.port) }}{{ .Values.ghostPath }}
  echo Admin URL : http://127.0.0.1:{{ default "80" (coalesce .Values.service.ports.http .Values.service.port) }}{{ default "/" .Values.ghostPath }}ghost
  kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ template "common.names.fullname" . }} {{ default "80" (coalesce .Values.service.ports.http .Values.service.port) }}:{{ default "80" (coalesce .Values.service.ports.http .Values.service.port) }}

{{- else if eq .Values.service.type "NodePort" }}

  export APP_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
  export APP_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "common.names.fullname" . }})

  echo Blog URL  : http://$APP_HOST:$APP_PORT{{ .Values.ghostPath }}
  echo Admin URL : http://$APP_HOST:$APP_PORT{{ default "/" .Values.ghostPath }}ghost

{{- else }}

  echo Blog URL  : http://{{ include "ghost.host" . }}
  echo Admin URL : http://{{ include "ghost.host" . }}ghost

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

2. Get your Ghost login credentials by running:

  echo Email:    {{ .Values.ghostEmail }}
  echo Password: $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "common.names.fullname" . }} -o jsonpath="{.data.{{- $ghostPasswordKey -}}}" | base64 -d)

{{- end }}
