## Introduction
This chart bootstraps a Wiki.js deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
It also optionally packages the [PostgreSQL](https://github.com/kubernetes/charts/tree/master/stable/postgresql) as the database but you are free to bring your own.
## Prerequisites
- PV provisioner support in the underlying infrastructure (with persistence storage enabled) if you want data persistance
## Installing the Chart
To install the chart with the release name `my-release` run the following from this (`helm`) directory:
The command deploys Wiki.js 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.
> **Warning**: Persistant Volume Claims for the database are not deleted automatically. They need to be manually deleted
```console
$ kubectl delete pvc/data-wiki-postgresql-0
```
## Configuration
The following table lists the configurable parameters of the Wiki.js chart and their default values.
By default, PostgreSQL is installed as part of the chart.
### Using an external PostgreSQL server
To use an external PostgreSQL server, set `postgresql.enabled` to `false` and then set `postgresql.postgresqlHost` and `postgresql.postgresqlPassword`. The other options (`postgresql.postgresqlDatabase`, `postgresql.postgresqlUser` and `postgresql.postgresqlPort`) may also want changing from their default values.
To use an SSL connection you can set `postgresql.ssl` to `true` and if needed the path to a Certificate of Authority can be set using `postgresql.ca` to `/path/to/ca`. Default `postgresql.ssl` value is `false`.
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.
## Ingress
This chart provides support for Ingress resource. If you have an available Ingress Controller such as Nginx or Traefik you maybe want to set `ingress.enabled` to true and choose an `ingress.hostname` for the URL. Then, you should be able to access the installation using that address.
