stable/dokuwiki/README.md
DokuWiki is a standards-compliant, simple to use wiki optimized for creating documentation. It is targeted at developer teams, workgroups, and small companies. All data is stored in plain text files, so no database is required.
Given the stable deprecation timeline, the Bitnami maintained DokuWiki Helm chart is now located at bitnami/charts.
The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the bitnami repo and using it during the installation (bitnami/<chart> instead of stable/<chart>)
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/<chart> # Helm 3
$ helm install --name my-release bitnami/<chart> # Helm 2
To update an exisiting stable deployment with a chart hosted in the bitnami repository you can execute
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm upgrade my-release bitnami/<chart>
Issues and PRs related to the chart itself will be redirected to bitnami/charts GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in this issue created as a common place for discussion.
$ helm install my-release stable/dokuwiki
This chart bootstraps a DokuWiki deployment on a Kubernetes cluster using the Helm package manager.
Bitnami charts can be used with Kubeapps 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.
To install the chart with the release name my-release:
$ helm install my-release stable/dokuwiki
The command deploys DokuWiki on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
To uninstall/delete the my-release deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.
The following table lists the configurable parameters of the DokuWiki chart and their default values.

The above parameters map to the env variables defined in bitnami/dokuwiki. For more information please refer to the bitnami/dokuwiki image documentation.
Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install my-release \
--set dokuwikiUsername=admin,dokuwikiPassword=password \
stable/dokuwiki
The above command sets the DokuWiki administrator account username and password to admin and password respectively.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
$ helm install my-release -f values.yaml stable/dokuwiki
Tip: You can use the default values.yaml
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.
The 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 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.
See the Parameters section to configure the PVC or to disable persistence.
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.
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:
$ kubectl patch deployment dokuwiki-dokuwiki --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
