## 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
## Adding the Wiki.js Helm Repository
```console
$ helm repo add requarks https://charts.js.wiki
```
## Installing the Chart
To install the chart with the release name `my-release` run the following:
### Using Helm 3:
```console
$ helm install my-release requarks/wiki
```
### Using Helm 2:
```console
$ helm install --name my-release requarks/wiki
```
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.
| Parameter | Description | Default |
| ------------------------------- | ------------------------------- | ---------------------------------------------------------- |
| `image.repository` | Wiki.js image | `requarks/wiki` |
| `image.tag` | Wiki.js image tag | `latest` |
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
| `replicacount` | Amount of wiki.js service pods to run | `1` |
| `revisionHistoryLimit` | Total amount of revision history points | `10` |
| `resources.limits` | wiki.js service resource limits | `nil` |
| `resources.requests` | wiki.js service resource requests | `nil` |
| `nodeSelector` | Node labels for wiki.js pod assignment | `{}` |
| `affinity` | Affinity settings for wiki.js pod assignment | `{}` |
| `schedulerName` | Name of an alternate scheduler for wiki.js pod | `nil` |
| `tolerations` | Toleration labels for wiki.jsk pod assignment | `[]` |
| `volumeMounts` | Volume mounts for Wiki.js container | `[]` |
| `volumes` | Volumes for Wiki.js Pod | `[]` |
| `ingress.enabled` | Enable ingress controller resource | `false` |
| `ingress.className` | Ingress class name | `""` |
| `ingress.annotations` | Ingress annotations | `{}` |
| `ingress.hosts` | List of ingress rules | `[{"host": "wiki.local", "paths": ["/"]}]` |
| `ingress.tls` | Ingress TLS configuration | `[]` |
| `sideload.enabled` | Enable sideloading of locale files from git | `false` |
| `sideload.repoURL` | Git repository URL containing locale files | `https://github.com/Requarks/wiki-localization` |
| `sideload.env` | Environment variables for sideload Container | `{}` |
| `postgresql.enabled` | Deploy postgres server (see below) | `true` |
| `postgresql.postgresqlDatabase` | Postgres database name | `wiki` |
| `postgresql.postgresqlUser` | Postgres username | `postgres` |
| `postgresql.postgresqlHost` | External postgres host | `nil` |
| `postgresql.postgresqlPassword` | External postgres password | `nil` |
| `postgresql.existingSecret` | Provide an existing `Secret` for postgres | `nil` |
| `postgresql.existingSecretKey` | The postgres password key in the existing `Secret` | `postgresql-password` |
| `postgresql.postgresqlPort` | External postgres port | `5432` |
| `postgresql.ssl` | Enable external postgres SSL connection | `false` |
| `postgresql.ca` | Certificate of Authority content for postgres | `nil` |
| `postgresql.persistence.enabled` | Enable postgres persistence using PVC | `true` |
| `postgresql.persistence.existingClaim` | Provide an existing `PersistentVolumeClaim` for postgres | `nil` |
| `postgresql.persistence.storageClass` | Postgres PVC Storage Class (example: `nfs`) | `nil` |
| `postgresql.persistence.size` | Postgers PVC Storage Request | `8Gi` |
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install --name my-release \
--set postgresql.persistence.enabled=false \
requarks/wiki
```
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 requarks/wiki
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## PostgresSQL
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`. To use an existing `Secret`, set `postgresql.existingSecret`. The other options (`postgresql.postgresqlDatabase`, `postgresql.postgresqlUser`, `postgresql.postgresqlPort` and `postgresql.existingSecretKey`) 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`.
If `postgresql.existingSecret` is not specified, you also need to add the following Helm template to your deployment in order to create the postgresql `Secret`:
```yaml
kind: Secret
apiVersion: v1
metadata:
name: {{ template "wiki.postgresql.secret" . }}
data:
{{ template "wiki.postgresql.secretKey" . }}: "{{ .Values.postgresql.postgresqlPassword | b64enc }}"
```
## Persistence
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 add `ingress.hosts` for the URL. Then, you should be able to access the installation using that address.
