# Bitnami Secure Images Helm chart for Matomo Matomo, formerly known as Piwik, is a real time web analytics program. It provides detailed reports on website visitors. [Overview of Matomo](https://matomo.org/) Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement. ## TL;DR ```console helm install my-release oci://registry-1.docker.io/bitnamicharts/matomo ``` ## Why use Bitnami Secure Images? Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise [OS Photon Linux](https://vmware.github.io/photon/). Why choose BSI images? - Hardened secure images of popular open source software with Near-Zero Vulnerabilities - Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores - Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM) - Software supply chain provenance attestation through in-toto - First class support for the internet’s favorite Helm charts Each image comes with valuable security metadata. You can view the metadata in [our public catalog here](https://app-catalog.vmware.com/bitnami/apps). Note: Some data is only available with [commercial subscriptions to BSI](https://bitnami.com/). ![Alt text](https://github.com/bitnami/containers/blob/main/BSI%20UI%201.png?raw=true "Application details") ![Alt text](https://github.com/bitnami/containers/blob/main/BSI%20UI%202.png?raw=true "Packaging report") If you are looking for our previous generation of images based on Debian Linux, please see the [Bitnami Legacy registry](https://hub.docker.com/u/bitnamilegacy). ## Introduction This chart bootstraps a [Matomo](https://github.com/bitnami/containers/tree/main/bitnami/matomo) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager. It also packages the [Bitnami MariaDB chart](https://github.com/bitnami/charts/tree/main/bitnami/mariadb) which is required for bootstrapping a MariaDB deployment as a database for the Matomo 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`: ```console helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/matomo ``` > 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 Matomo 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` ## 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](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). 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](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/). ### 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](https://matomo.org/faq/how-to/faq_139/) - Update the password secret with the new values (replace the SECRET_NAME, PASSWORD and SMTP_PASSWORD placeholders) ```shell kubectl create secret generic SECRET_NAME --from-literal=matomo-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](https://github.com/Lusitaniae/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](https://github.com/bitnami/charts/tree/main/bitnami/prometheus) or the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) 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: ```text no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1" ``` Install the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) for having the necessary CRDs and the Prometheus Operator. ### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html) 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. ### Image The `image` parameter allows specifying which image will be pulled for the chart. #### Private registry If you configure the `image` value to one in a private registry, you will need to [specify an image pull secret](https://kubernetes.io/docs/concepts/containers/images/#specifying-imagepullsecrets-on-a-pod). 1. Manually create image pull secret(s) in the namespace. See [this YAML example reference](https://kubernetes.io/docs/concepts/containers/images/#creating-a-secret-with-a-docker-config). Consult your image registry's documentation about getting the appropriate secret. 2. Note that the `imagePullSecrets` configuration value cannot currently be passed to helm using the `--set` parameter, so you must supply these using a `values.yaml` file, such as: ```yaml imagePullSecrets: - name: SECRET_NAME ``` 3. Install the chart ### 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. ### 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](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html). ## Persistence The [Bitnami Matomo](https://github.com/bitnami/containers/tree/main/bitnami/matomo) image stores the Matomo data and configurations at the `/bitnami/matomo` path 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 [Parameters](#parameters) section to configure the PVC or to disable persistence. ### Existing PersistentVolumeClaim 1. Create the PersistentVolume 2. Create the PersistentVolumeClaim 3. Install the chart ```console helm install my-release --set persistence.existingClaim=PVC_NAME oci://REGISTRY_NAME/REPOSITORY_NAME/matomo ``` > 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`. ### Host path #### System compatibility - The local filesystem accessibility to a container in a pod with `hostPath` has been tested on OSX/MacOS with xhyve, and Linux with VirtualBox. - Windows has not been tested with the supported VM drivers. Minikube does however officially support [Mounting Host Folders](https://minikube.sigs.k8s.io/docs/handbook/mount/) per pod. Or you may manually sync your container whenever host files are changed with tools like [docker-sync](https://github.com/EugenMayer/docker-sync) or [docker-bg-sync](https://github.com/cweagans/docker-bg-sync). #### Mounting steps 1. The specified `hostPath` directory must already exist (create one if it does not). 2. Install the chart ```console helm install my-release --set persistence.hostPath=/PATH/TO/HOST/MOUNT oci://REGISTRY_NAME/REPOSITORY_NAME/matomo ``` > 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`. This will mount the `matomo-data` volume into the `hostPath` directory. The site data will be persisted if the mount path contains valid data, else the site data will be initialized at first launch. 3. Because the container cannot control the host machine's directory permissions, you must set the Matomo file directory permissions yourself ## Parameters ### Global parameters | Name | Description | Value | | ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | | `global.imageRegistry` | Global Docker image registry | `""` | | `global.imagePullSecrets` | Global Docker registry secret names as an array | `[]` | | `global.defaultStorageClass` | Global default StorageClass for Persistent Volume(s) | `""` | | `global.security.allowInsecureImages` | Allows skipping image verification | `false` | | `global.compatibility.openshift.adaptSecurityContext` | Adapt the securityContext sections of the deployment to make them compatible with Openshift restricted-v2 SCC: remove runAsUser, runAsGroup and fsGroup and let the platform use their allowed default IDs.

For example, ```console helm install my-release \ --set matomoUsername=user,matomoPassword=password,mariadb.auth.rootPassword=secretpassword \ oci://REGISTRY_NAME/REPOSITORY_NAME/matomo ``` > 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 Matomo administrator account username and password to `user` 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, ```console helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/matomo ``` > 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](https://github.com/bitnami/charts/tree/main/bitnami/matomo/values.yaml) ## Troubleshooting Find more information about how to deal with common errors related to Bitnami's Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues). ## Upgrading ### To 11.0.0 This major release bumps the MariaDB version to 12.0. Follow the [upstream instructions](https://mariadb.com/docs/server/server-management/install-and-upgrade-mariadb/upgrading) for upgrading from MariaDB 11.8 to 12.0. No major issues are expected during the upgrade. ### To 10.0.0 This major release bumps the MariaDB version to 11.8. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-11-4-to-mariadb-11-8/) for upgrading from MariaDB 11.4 to 11.8. No major issues are expected during the upgrade. ### To 9.1.0 This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850). ### To 9.0.0 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): ```shell kubectl delete sts RELEASE_NAME-mariadb --cascade=false ``` Then execute `helm upgrade` as usual. ### To 8.0.0 This major release bumps the MariaDB version to 11.4. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-11-3-to-mariadb-11-4/) for upgrading from MariaDB 11.3 to 11.4. No major issues are expected during the upgrade. ### To 7.0.0 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](https://github.com/bitnami/charts/pull/24804); no major issues are expected during the upgrade. ### To 6.0.0 Moved persistence config for the cronjobs from `persistence` to `cronjobs.archive.persistence` and `cronjobs.taskScheduler.persistence` respectively. Moved resource config for the archive cronjob from `resources` to `cronjobs.archive.resources`. ### To 4.0.0 This major release bumps the MariaDB version to 11.2. No major issues are expected during the upgrade. ### To 3.2.0 This version deprecates `cronjobs.enabled` value in favor of `cronjobs.taskScheduler.enabled` and `cronjobs.archive.enabled` values. ### To 3.0.0 This major release bumps the MariaDB version to 11.1. No major issues are expected during the upgrade. ### To 2.0.0 This major release bumps the MariaDB version to 11.0. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-10-11-to-mariadb-11-0/) for upgrading from MariaDB 10.11 to 11.0. No major issues are expected during the upgrade. ### To 1.0.0 This major release bumps the MariaDB version to 10.11. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for upgrading from MariaDB 10.6 to 10.11.
