# Ghost
[Ghost](https://ghost.org/) is one of the most versatile open source content management systems on the market.
## TL;DR;
```console
$ helm install stable/ghost
```
## Introduction
This chart bootstraps a [Ghost](https://github.com/bitnami/bitnami-docker-ghost) 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 Ghost 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 stable/ghost
```
The command deploys Ghost 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 Ghost chart and their default values.
| Parameter | Description | Default |
|-------------------------------|---------------------------------------------------------------|----------------------------------------------------------|
| `image` | Ghost image | `bitnami/ghost:{VERSION}` |
| `imagePullPolicy` | Image pull policy | `Always` if `image` tag is `latest`, else `IfNotPresent` |
| `ghostHost` | Ghost host to create application URLs | `nil` |
| `ghostPort` | Ghost port to create application URLs along with host | `80` |
| `ghostLoadBalancerIP` | `loadBalancerIP` for the Ghost Service | `nil` |
| `ghostUsername` | User of the application | `user@example.com` |
| `ghostPassword` | Application password | Randomly generated |
| `ghostEmail` | Admin email | `user@example.com` |
| `ghostBlogTitle` | Ghost Blog name | `User's Blog` |
| `allowEmptyPassword` | Allow DB blank passwords | `yes` |
| `externalDatabase.host` | Host of the external database | `nil` |
| `externalDatabase.user` | Existing username in the external db | `bn_ghost` |
| `externalDatabase.password` | Password for the above username | `nil` |
| `externalDatabase.database` | Name of the existing database | `bitnami_ghost` |
| `mariadb.enabled` | Whether or not to install MariaDB (disable if using external) | `true` |
| `mariadb.mariadbRootPassword` | MariaDB admin password | `nil` |
| `mariadb.mariadbDatabase` | MariaDB Database name to create | `bitnami_ghost` |
| `mariadb.mariadbUser` | MariaDB Database user to create | `bn_ghost` |
| `mariadb.mariadbPassword` | MariaDB Password for user | _random 10 character long alphanumeric string_ |
| `serviceType` | Kubernetes Service type | `LoadBalancer` |
| `persistence.enabled` | Enable persistence using PVC | `true` |
| `persistence.storageClass` | PVC Storage Class for Ghost volume | `nil` (uses alpha storage annotation) |
| `persistence.accessMode` | PVC Access Mode for Ghost volume | `ReadWriteOnce` |
| `persistence.size` | PVC Storage Request for Ghost volume | `8Gi` |
| `resources` | CPU/Memory resource requests/limits | Memory: `512Mi`, CPU: `300m` |
The above parameters map to the env variables defined in [bitnami/ghost](http://github.com/bitnami/bitnami-docker-ghost). For more information please refer to the [bitnami/ghost](http://github.com/bitnami/bitnami-docker-ghost) image documentation.
> **Note**:
>
> For the Ghost application function correctly, you should specify the `ghostHost` parameter to specify the FQDN (recommended) or the public IP address of the Ghost service.
>
> Optionally, you can specify the `ghostLoadBalancerIP` parameter to assign a reserved IP address to the Ghost service of the chart. However please note that this feature is only available on a few cloud providers (f.e. GKE).
>
> To reserve a public IP address on GKE:
>
> ```bash
> $ gcloud compute addresses create ghost-public-ip
> ```
>
> The reserved IP address can be associated to the Ghost service by specifying it as the value of the `ghostLoadBalancerIP` parameter while installing the chart.
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install --name my-release \
--set ghostUsername=admin,ghostPassword=password,mariadb.mariadbRootPassword=secretpassword \
stable/ghost
```
The above command sets the Ghost 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/ghost
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Using an existing database
Sometimes you may want to have Ghost connect to an external database rather than installing one inside your cluster, e.g. to use a managed database service, or use run a single database server for all your applications. To do this, the chart allows you to specify credentials for an external database under the [`externalDatabase` parameter](#configuration). You should also disable the MariaDB installation with the `mariadb.enabled` option. For example:
```console
$ helm install stable/ghost \
--set mariadb.enabled=false,externalDatabase.host=myexternalhost,externalDatabase.user=myuser,externalDatabase.password=mypassword,externalDatabase.database=mydatabase
```
## Persistence
The [Bitnami Ghost](https://github.com/bitnami/bitnami-docker-ghost) image stores the Ghost data and configurations at the `/bitnami/ghost` 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.

### ERROR: You did not provide an external host in your 'helm install' call ###

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:

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

Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "ghost.fullname" . }}'
export APP_HOST=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "ghost.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
{{- end }}
2. Complete your Ghost deployment by running:
helm upgrade {{ .Release.Name }} \
--set serviceType={{ .Values.serviceType }},ghostHost=$APP_HOST stable/ghost
{{- else -}}
1. Get the Ghost URL by running:
{{- if eq .Values.serviceType "ClusterIP" }}

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

2. Get your Ghost login credentials by running:
echo Email: {{ .Values.ghostEmail }}
echo Password: $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "ghost.fullname" . }} -o jsonpath="{.data.ghost-password}" | base64 --decode)
