## TL;DR

```console
helm install my-release oci://registry-1.docker.io/bitnamicharts/dokuwiki
```

## Introduction

This chart bootstraps a [DokuWiki](https://github.com/bitnami/containers/tree/main/bitnami/dokuwiki) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://registry-1.docker.io/bitnamicharts/dokuwiki
```

The command deploys DokuWiki on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) 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.

The above parameters map to the env variables defined in [bitnami/dokuwiki](https://github.com/bitnami/containers/tree/main/bitnami/dokuwiki). For more information please refer to the [bitnami/dokuwiki](https://github.com/bitnami/containers/tree/main/bitnami/dokuwiki) image documentation.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
  --set dokuwikiUsername=admin,dokuwikiPassword=password \
    oci://registry-1.docker.io/bitnamicharts/dokuwiki
```

The above command sets the DokuWiki administrator account username and password to `admin` and `password` respectively.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://registry-1.docker.io/bitnamicharts/dokuwiki
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [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.

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

## Persistence

The [Bitnami DokuWiki](https://github.com/bitnami/containers/tree/main/bitnami/dokuwiki) image stores the DokuWiki data and configurations at the `/bitnami/dokuwiki` path of the container.

Persistent Volume Claims are used to keep the data across deployments. There is a [known issue](https://github.com/kubernetes/kubernetes/issues/39178) in Kubernetes Clusters with EBS in different availability zones. Ensure your cluster is configured properly to create Volumes in the same availability zone where the nodes are running. Kuberentes 1.12 solved this issue with the [Volume Binding Mode](https://kubernetes.io/docs/concepts/storage/storage-classes/#volume-binding-mode).

See the [Parameters](#parameters) section to configure the PVC or to disable persistence.

## Certificates

### CA Certificates

Custom CA certificates not included in the base docker image can be added with
the following configuration. The secret must exist in the same namespace as the
deployment. Will load all certificates files it finds in the secret.

```yaml
certificates:
  customCAs:
  - secret: my-ca-1
  - secret: my-ca-2
```

#### CA Certificates secret

Secret can be created with:

```console
kubectl create secret generic my-ca-1 --from-file my-ca-1.crt
```

### TLS Certificate

A web server TLS Certificate can be injected into the container with the
following configuration. The certificate will be stored at the location
specified in the certificateLocation value.

```yaml
certificates:
  customCertificate:
    certificateSecret: my-secret
    certificateLocation: /ssl/server.pem
    keyLocation: /ssl/key.pem
    chainSecret:
      name: my-cert-chain-secret
      key: chain.pem
```

#### TLS secret

The certificate tls secret can be created with:

```console
kubectl create secret tls my-secret --cert tls.crt --key tls.key
```

The certificate chain is created with:

```console
kubectl create secret generic my-ca-1 --from-file my-ca-1.crt
```

## Upgrading

### To 12.0.0

Some of the chart values were changed to adapt to the latest Bitnami standards. More specifically:

- `containerPort` was changed to `containerPorts.http`
- `service.port` was changed to `service.ports.http`

No issues should be expected when upgrading.

### To 11.0.0

This version standardizes the way of defining Ingress rules. When configuring a single hostname for the Ingress rule, set the `ingress.hostname` value. When defining more than one, set the `ingress.extraHosts` array. Apart from this case, no issues are expected to appear when upgrading.

### To 10.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

#### What changes were introduced in this major version?

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

#### Considerations when upgrading to this version

- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

### To 7.0.0

This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.

The [Bitnami Dokuwiki](https://github.com/bitnami/containers/tree/main/bitnami/dokuwiki) image was migrated to a "non-root" user approach. Previously the container ran as the `root` user and the Apache daemon was started as the `daemon` user. From now on, both the container and the Apache daemon run as user `1001`. You can revert this behavior by setting the parameters `containerSecurityContext.runAsUser` to `root`.

Consequences:

- The HTTP/HTTPS ports exposed by the container are now `8080/8443` instead of `80/443`.
- Backwards compatibility is not guaranteed.

To upgrade to `7.0.0`, backup Drupal data and the previous MariaDB databases, install a new Drupal chart and import the backups and data, ensuring the `1001` user has the appropriate permissions on the migrated volume.

### To 6.0.0

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/pull/17294> 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 3.0.0

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 3.0.0. The following example assumes that the release name is dokuwiki:

```console
kubectl patch deployment dokuwiki-dokuwiki --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
```

## Community supported solution

Please, note this Helm chart is a community-supported solution. This means that the Bitnami team is not actively working on new features/improvements nor providing support through GitHub Issues for this Helm chart. Any new issue will stay open for 20 days to allow the community to contribute, after 15 days without activity the issue will be marked as stale being closed after 5 days.

The Bitnami team will review any PR that is created, feel free to create a PR if you find any issue or want to implement a new feature.

New versions are not going to be affected. Once a new version is released in the upstream project, the Bitnami container image will be updated to use the latest version.
