@ -14,10 +14,14 @@ This chart bootstraps a [Ghost](https://github.com/bitnami/bitnami-docker-ghost)
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.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).
## Prerequisites
- Kubernetes 1.4+ with Beta APIs enabled
- Kubernetes 1.12+
- Helm 2.11+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Using an existing database
## Configuration and installation details
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:
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### 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](#parameters). You should also disable the MariaDB installation with the `mariadb.enabled` option. For example using the following parameters:
```console
$ helm install stable/ghost \
--set mariadb.enabled=false,externalDatabase.host=myexternalhost,externalDatabase.user=myuser,externalDatabase.password=mypassword,externalDatabase.database=mydatabase
mariadb.enabled=false
externalDatabase.host=myexternalhost
externalDatabase.user=myuser
externalDatabase.password=mypassword
externalDatabase.database=mydatabase
```
## Persistence
@ -121,4 +178,24 @@ $ helm install stable/ghost \
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.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
## Upgrading
### To 9.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pulls/17297 the `apiVersion` of the deployment resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.
This major version signifies this change.
### To 5.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 5.0.0. The following example assumes that the release name is ghost:
```console
$ kubectl patch deployment ghost-ghost --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
$ kubectl delete statefulset ghost-mariadb --cascade=false
```
