⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new Bitnami Secure Images initiative. As part of this transition:

• Granting community users access for the first time to security-optimized versions of popular container images.
• Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
• Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
• For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the Bitnami Secure Images announcement.

Introduction

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.

Prerequisites

• Kubernetes 1.23+
• Helm 3.8.0+
• 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:

helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/moodle

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

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

Configuration and installation details

Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the resources value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the resourcesPreset values, which automatically sets the resources section according to different presets. Check these presets in the bitnami/common chart. However, in production workloads using resourcesPreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

Update credentials

Bitnami charts configure credentials at first boot. Any further change in the secrets or credentials require manual intervention. Follow these instructions:

• Update the user password following the upstream documentation
• Update the password secret with the new values (replace the SECRET_NAME, PASSWORD and SMTP_PASSWORD placeholders)

kubectl create secret generic SECRET_NAME --from-literal=moodle-password=PASSWORD --from-literal=smtp-password=SMTP_PASSWORD --dry-run -o yaml | kubectl apply -f -

Prometheus metrics

This chart can be integrated with Prometheus by setting metrics.enabled to true. This will deploy a sidecar container with apache-exporter in all pods and a metrics service, which can be configured under the metrics.service section. This metrics service will have the necessary annotations to be automatically scraped by Prometheus.

Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the Bitnami Prometheus helm chart or the Bitnami Kube Prometheus helm chart to easily have a working Prometheus in your cluster.

Integration with Prometheus Operator

The chart can deploy ServiceMonitor objects for integration with Prometheus Operator installations. To do so, set the value metrics.serviceMonitor.enabled=true. Ensure that the Prometheus Operator CustomResourceDefinitions are installed in the cluster or it will fail with the following error:

no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"

Install the Bitnami Kube Prometheus helm chart for having the necessary CRDs and the Prometheus Operator.

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):

ingress.enabled=True
ingress.hosts[0]=moodle.domain.com
serviceType=ClusterIP
moodleUsername=admin
moodlePassword=password
mariadb.mariadbRootPassword=secretpassword

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

Ingress TLS

If your cluster allows automatic creation/retrieval of TLS certificates, 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:

ingress:
  ## If true, Moodle(TM) server Ingress will be created
  ##
  enabled: true

  ## Moodle(TM) server Ingress annotations
  ##
  annotations: {}
  #   kubernetes.io/ingress.class: nginx
  #   kubernetes.io/tls-acme: 'true'

  ## Moodle(TM) server Ingress hostnames
  ## Must be provided if Ingress is enabled
  ##
  hosts:
    - moodle.domain.com

  ## Moodle(TM) server Ingress TLS configuration
  ## Secrets must be manually created in the namespace
  ##
  tls:
    - secretName: moodle-server-tls
      hosts:
        - moodle.domain.com

Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using Velero, a Kubernetes backup/restore tool. Find the instructions for using Velero in this guide.

Persistence

The Bitnami Container Image for Moodle™ 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.

helm install my-release \
  --set moodleUsername=admin,moodlePassword=password,mariadb.auth.rootPassword=secretpassword \
    oci://REGISTRY_NAME/REPOSITORY_NAME/moodle

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

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.

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,

helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/moodle

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts. Tip: You can use the default values.yaml

Upgrading

To 28.0.0

This major release bumps the MariaDB version to 12.0. Follow the upstream instructions for upgrading from MariaDB 11.8 to 12.0. No major issues are expected during the upgrade.

To 27.0.0

This major release bumps the MariaDB version to 11.8. Follow the upstream instructions for upgrading from MariaDB 11.4 to 11.8. No major issues are expected during the upgrade.

To 25.1.0

This version introduces image verification for security purposes. To disable it, set global.security.allowInsecureImages to true. More details at GitHub issue.

To 25.0.0

This major bump updates the MariaDB subchart to version 20.0.0. This subchart updates the StatefulSet objects serviceName to use a headless service, as the current non-headless service attached to it was not providing DNS entries. This will cause an upgrade issue because it changes "immutable fields". To workaround it, delete the StatefulSet objects as follows (replace the RELEASE_NAME placeholder):

kubectl delete sts RELEASE_NAME-mariadb --cascade=false

Then execute helm upgrade as usual.

To 24.0.0

This major updates Moodle to branch 4.5. Check the upstream documentation to ensure the migration to the new version is complete.

To 23.0.0

This major release bumps the MariaDB version to 11.4. Follow the upstream instructions for upgrading from MariaDB 11.3 to 11.4. No major issues are expected during the upgrade.

To 21.0.0

This major bump changes the following security defaults:

• resourcesPreset is changed from none to the minimum size working in our test suites (NOTE: resourcesPreset is not meant for production usage, but resources adapted to your use case).
• global.compatibility.openshift.adaptSecurityContext is changed from disabled to auto.
• The networkPolicy section has been normalized amongst all Bitnami charts. Compared to the previous approach, the values section has been simplified (check the Parameters section) and now it set to enabled=true by default. Egress traffic is allowed by default and ingress traffic is allowed by all pods but only to the ports set in containerPorts and extraContainerPorts.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

Also, this major release bumps the MariaDB chart version to 18.x.x; no major issues are expected during the upgrade.

To 20.0.0

This major release bumps the MariaDB version to 11.2. No major issues are expected during the upgrade.

To 18.0.0

This major release bumps the MariaDB version to 11.1. No major issues are expected during the upgrade.

To 17.0.0

This major release bumps the MariaDB version to 11.0. Follow the upstream instructions for upgrading from MariaDB 10.11 to 11.0. No major issues are expected during the upgrade.

To 15.0.0

This major release bumps the MariaDB version to 10.11. Follow the upstream instructions for upgrading from MariaDB 10.6 to 10.11. No major issues are expected during the upgrade.

To 13.0.0

This major release bumps the MariaDB version to 10.6. Follow the upstream instructions for upgrading from MariaDB 10.5 to 10.6. No major issues are expected during the upgrade.

To 12.0.0

This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.

Affected values:

• service.port was deprecated. We recommend using service.ports.http instead.
• service.httpsPort was deprecated. We recommend using service.ports.https instead.

Additionally updates the MariaDB subchart to it newest major, 10.0.0, which contains similar changes. Check MariaDB Upgrading Notes for more information.

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, 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 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

To 9.0.0

MariaDB dependency version was bumped to a new major version that introduces several incompatilibites. Therefore, backwards compatibility is not guaranteed unless an external database is used. Check MariaDB Upgrading Notes for more information.

To upgrade to 9.0.0, it should be done reusing the PVCs used to hold both the MariaDB and Moodle™ data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is moodle):

NOTE: Please, create a backup of your database before running any of those actions. The steps below would be only valid if your application (e.g. any plugins or custom code) is compatible with MariaDB 10.5.x

Obtain the credentials and the names of the PVCs used to hold both the MariaDB and Moodle™ data on your current release:

export MOODLE_PASSWORD=$(kubectl get secret --namespace default moodle -o jsonpath="{.data.moodle-password}" | base64 -d)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default moodle-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default moodle-mariadb -o jsonpath="{.data.mariadb-password}" | base64 -d)
export MARIADB_PVC=$(kubectl get pvc -l app=mariadb,component=master,release=moodle -o jsonpath="{.items[0].metadata.name}")

Upgrade your release (maintaining the version) disabling MariaDB and scaling Moodle™ replicas to 0:

helm upgrade moodle oci://REGISTRY_NAME/REPOSITORY_NAME/moodle --set moodlePassword=$MOODLE_PASSWORD --set replicaCount=0 --set mariadb.enabled=false --version 8.1.6

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

Finally, upgrade you release to 9.0.0 reusing the existing PVC, and enabling back MariaDB:

helm upgrade moodle oci://REGISTRY_NAME/REPOSITORY_NAME/moodle --set mariadb.primary.persistence.existingClaim=$MARIADB_PVC --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD --set mariadb.auth.password=$MARIADB_PASSWORD --set moodlePassword=$MOODLE_PASSWORD

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

You should see the lines below in MariaDB container logs:

$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=moodle,app.kubernetes.io/name=mariadb,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
...
mariadb 12:13:24.98 INFO  ==> Using persisted data
mariadb 12:13:25.01 INFO  ==> Running mysql_upgrade
...

To 8.0.0

The Bitnami Container Image for Moodle™ was updated to support "non-root" user approach, however, it is not enabled by default. The container still runs as the root user and the Apache daemon is started as the daemon user, due to running Cron as a service, which requires running as root.

If you want to run with a non-root user, you need to set podSecurityContext.enabled=true and containerSecurity.context.enabled=true. In addition to that, you will also need to change the default Apache HTTP ports to run as a non-privileged user by setting containerPorts.http and containerPorts.https to a non-privileged port number (higher than 1024, i.e. 8080 and 8443, respectively). Note that, when running as a non-root user, Cron will not supported and therefore scheduled tasks will not be enabled for Moodle™.

This upgrade also adapts the chart to the latest Bitnami good practices. Check the Parameters section for more information.

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 https://github.com/helm/charts/pull/17301 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
