DokuWiki

DokuWiki 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.

TL;DR;

$ helm install stable/dokuwiki

Introduction

This chart bootstraps a DokuWiki deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled
• PV provisioner support in the underlying infrastructure

Installing the Chart

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

$ helm install --name my-release stable/dokuwiki

The command deploys DokuWiki on the Kubernetes cluster in the default configuration. The 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:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following table lists the configurable parameters of the DokuWiki chart and their default values.

Parameter	Description	Default

service.nodePorts.https	Kubernetes https node port	""
ingress.enabled	Enable ingress controller resource	false
ingress.hosts[0].name	Hostname to your Joomla! installation	joomla.local
ingress.hosts[0].path	Path within the url structure	/
ingress.hosts[0].tls	Utilize TLS backend in ingress	false
ingress.hosts[0].tlsSecret	TLS Secret (certificates)	joomla.local-tls-secret
ingress.hosts[0].annotations	Annotations for this host's ingress record	[]
ingress.secrets[0].name	TLS Secret Name	nil
ingress.secrets[0].certificate	TLS Secret Certificate	nil
ingress.secrets[0].key	TLS Secret Key	nil
persistence.enabled	Enable persistence using PVC	true
persistence.apache.storageClass	PVC Storage Class for apache volume	nil (uses alpha storage class annotation)
persistence.apache.accessMode	PVC Access Mode for apache volume	ReadWriteOnce
persistence.apache.size	PVC Storage Request for apache volume	1Gi
persistence.dokuwiki.storageClass	PVC Storage Class for DokuWiki volume	nil (uses alpha storage class annotation)
persistence.dokuwiki.accessMode	PVC Access Mode for DokuWiki volume	ReadWriteOnce
persistence.dokuwiki.size	PVC Storage Request for DokuWiki volume	8Gi
resources	CPU/Memory resource requests/limits	Memory: 512Mi, CPU: 300m
livenessProbe.enabled	Enable/disable the liveness probe	true
livenessProbe.initialDelaySeconds	Delay before liveness probe is initiated	120
livenessProbe.periodSeconds	How often to perform the probe	10
livenessProbe.timeoutSeconds	When the probe times out	5
livenessProbe.failureThreshold	Minimum consecutive failures to be considered failed	6
livenessProbe.successThreshold	Minimum consecutive successes to be considered successful	1
readinessProbe.enabled	Enable/disable the readiness probe	true
readinessProbe.initialDelaySeconds	Delay before readinessProbe is initiated	30
readinessProbe.periodSeconds	How often to perform the probe	10
readinessProbe.timeoutSeconds	When the probe times out	5
readinessProbe.failureThreshold	Minimum consecutive failures to be considered failed	6
readinessProbe.successThreshold	Minimum consecutive successes to be considered successful	1

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 --name 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 --name my-release -f values.yaml stable/dokuwiki

Tip: You can use the default values.yaml

Persistence

The Bitnami DokuWiki image stores the DokuWiki data and configurations at the /bitnami/dokuwiki 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 section to configure the PVC or to disable persistence.
