Moodle is a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create personalized learning environments

This Helm chart is deprecated

Given the stable deprecation timeline, the Bitnami maintained Moodle 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
$ 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
$ 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/moodle


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

It also packages the Bitnami MariaDB chart which is required for bootstrapping a MariaDB deployment for the database requirements of the Moodle application.

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.


  • Kubernetes 1.12+
  • Helm 2.11+ or Helm 3.0-beta3+
  • 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:

$ helm install my-release stable/moodle

The command deploys Moodle 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

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.


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

The above parameters map to the env variables defined in bitnami/moodle. For more information please refer to the bitnami/moodle image documentation.

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

$ helm install my-release \
  --set moodleUsername=admin,moodlePassword=password,mariadb.mariadbRootPassword=secretpassword \

The above command sets the Moodle administrator account username and password to admin and password respectively. Additionally, it sets the MariaDB root user password to secretpassword.

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/moodle

Tip: You can use the default values.yaml

Configuration and installation details

Rolling VS Immutable tags

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.

Ingress without TLS

For using ingress (example without TLS):


These are the 3 mandatory parameters when Ingress is desired: ingress.enabled=True, ingress.hosts[0] and serviceType=ClusterIP

Ingress TLS

If your cluster allows automatic creation/retrieval of TLS certificates (e.g. kube-lego), please refer to the documentation for that mechanism.

To manually configure TLS, first create/retrieve a key & certificate pair for the address(es) you wish to protect. Then create a TLS secret (named moodle-server-tls in this example) in the namespace. Include the secret’s name, along with the desired hostnames, in the Ingress TLS section of your custom values.yaml file:

  ## If true, Moodle server Ingress will be created
  enabled: true

  ## Moodle server Ingress annotations
  annotations: {}
  # nginx
  # 'true'

  ## Moodle server Ingress hostnames
  ## Must be provided if Ingress is enabled

  ## Moodle server Ingress TLS configuration
  ## Secrets must be manually created in the namespace
    - secretName: moodle-server-tls


The Bitnami Moodle image stores the Moodle data and configurations at the /bitnami/moodle 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, vpshere, and minikube. See the Parameters section to configure the PVC or to disable persistence. You may want to review the PV reclaim policy and update as required. By default, it’s set to delete, and when Moodle is uninstalled, data is also removed.


To 7.0.0

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 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 moodle:

$ kubectl patch deployment moodle-moodle --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
$ kubectl delete statefulset moodle-mariadb --cascade=false
