Bitnami package for Magento

Magento is a powerful open source e-commerce platform. With easy customizations and rich features, it allows retailers to grow their online businesses in a cost-effective way.

Overview of Magento

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

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

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository.

Introduction

This chart bootstraps a Magento 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 as a database for the Magento application.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

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/magento

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 Magento 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 resourcePreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

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.

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.

  1. Manually create image pull secret(s) in the namespace. See this YAML example reference. 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:

    imagePullSecrets:
      - name: SECRET_NAME
    
  3. Install the chart

Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as nginx-ingress-controller or contour you can utilize the ingress controller to serve your application.

To enable ingress integration, please set ingress.enabled to true.

Hosts

Most likely you will only want to have one hostname that maps to this Magento installation. If that’s your case, the property ingress.hostname will set it. However, it is possible to have more than one host. To facilitate this, the ingress.extraHosts object can be specified as an array. You can also use ingress.extraTLS to add the TLS configuration for extra hosts.

For each host indicated at ingress.extraHosts, please indicate a name, path, and any annotations that you may want the ingress controller to know about.

For annotations, please see this document. Not all annotations are supported by all ingress controllers, but this document does a good job of indicating which annotation is supported by many popular ingress controllers.

Certificates

TLS Secrets

This chart will facilitate the creation of TLS secrets for use with the ingress controller, however, this is not required. There are three common use cases:

  • Helm generates/manages certificate secrets.
  • User generates/manages certificates separately.
  • An additional tool (like cert-manager) manages the secrets for the application.

In the first two cases, it’s needed a certificate and a key. We would expect them to look like this:

  • certificate files should look like (and there can be more than one certificate if there is a certificate chain)

    -----BEGIN CERTIFICATE-----
    MIID6TCCAtGgAwIBAgIJAIaCwivkeB5EMA0GCSqGSIb3DQEBCwUAMFYxCzAJBgNV
    ...
    jScrvkiBO65F46KioCL9h5tDvomdU1aqpI/CBzhvZn1c0ZTf87tGQR8NK7v7
    -----END CERTIFICATE-----
    
  • keys should look like:

    -----BEGIN RSA PRIVATE KEY-----
    MIIEogIBAAKCAQEAvLYcyu8f3skuRyUgeeNpeDvYBCDcgq+LsWap6zbX5f8oLqp4
    ...
    wrj2wDbCDCFmfqnSJ+dKI3vFLlEz44sAV8jX/kd4Y6ZTQhlLbYc=
    -----END RSA PRIVATE KEY-----
    

If you are going to use Helm to manage the certificates, please copy these values into the certificate and key values for a given ingress.secrets entry.

If you are going to manage TLS secrets outside of Helm, please know that you can create a TLS secret (named magento.local-tls for example).

CA Certificates

Custom CA certificates not included in the base docker image can be added by means of existing secrets. The secret must exist in the same namespace and contain the desired CA certificates to import. By default, all found certificate files will be loaded.

certificates:
  customCAs:
  - secret: my-ca-1
  - secret: my-ca-2
Note

Tip! You can create a secret containing your CA certificates using the following command:

kubectl create secret generic my-ca-1 --from-file my-ca-1.crt

Adding extra environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the extraEnvVars property.

extraEnvVars:
  - name: LOG_LEVEL
    value: DEBUG

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the extraEnvVarsCM or the extraEnvVarsSecret values.

Sidecars and Init Containers

If you have a need for additional containers to run within the same pod as Magento (e.g. an additional metrics or logging exporter), you can do so via the sidecars config parameter. Simply define your container according to the Kubernetes container spec.

sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
       containerPort: 1234

If these sidecars export extra ports, you can add extra port definitions using the service.extraPorts value:

service:
...
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311

Similarly, you can add extra init containers using the initContainers parameter.

initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234

Using an external database

Sometimes you may want to have Magento connect to an external database rather than installing one inside your cluster, e.g. to use a managed database service, or use run a single database server for all your applications. To do this, the chart allows you to specify credentials for an external database under the externalDatabase parameter. You should also disable the MariaDB installation with the mariadb.enabled option. For example with the following parameters:

mariadb.enabled=false
externalDatabase.host=myexternalhost
externalDatabase.user=myuser
externalDatabase.password=mypassword
externalDatabase.database=mydatabase
externalDatabase.port=3306

Note also if you disable MariaDB per above you MUST supply values for the externalDatabase connection.

In case the database already contains data from a previous Magento installation, you need to set the magentoSkipInstall parameter to true. Otherwise, the container would execute the installation wizard and could modify the existing data in the database. This parameter force the container to not execute the Magento installation wizard. This is necessary in case you use a database that already has Magento data +info.

Deploying extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app’s configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the extraDeploy parameter.

Setting Pod’s affinity

This chart allows you to set your custom affinity using the affinity parameter. Find more infomation about Pod’s affinity in the kubernetes documentation.

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.

Persistence

The Bitnami Magento image stores the Magento data and configurations at the /bitnami/magento and /bitnami/apache paths 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.

Existing PersistentVolumeClaim

  1. Create the PersistentVolume
  2. Create the PersistentVolumeClaim
  3. Install the chart

    helm install my-release --set persistence.existingClaim=PVC_NAME oci://REGISTRY_NAME/REPOSITORY_NAME/magento
    
    Note

    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 per pod. Or you may manually sync your container whenever host files are changed with tools like docker-sync or docker-bg-sync.

Mounting steps

  1. The specified hostPath directory must already exist (create one if it does not).
  2. Install the chart

    helm install my-release --set persistence.hostPath=/PATH/TO/HOST/MOUNT oci://REGISTRY_NAME/REPOSITORY_NAME/magento
    
    Note

    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 magento-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 Magento file directory permissions yourself and disable or clear Magento cache.

Other Parameters

Name Description Value
autoscaling.enabled Enable autoscaling for replicas false
autoscaling.minReplicas Minimum number of replicas 1
autoscaling.maxReplicas Maximum number of replicas 11
autoscaling.targetCPU Target CPU utilization percentage ""
autoscaling.targetMemory Target Memory utilization percentage ""

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

Note

:

For Magento to function correctly, you should specify the magentoHost parameter to specify the FQDN (recommended) or the public IP address of the Magento service.

Optionally, you can specify the service.loadBalancerIP parameter to assign a reserved IP address to the Magento service of the chart. However please note that this feature is only available on a few cloud providers (f.e. GKE).

To reserve a public IP address on GKE:

$ gcloud compute addresses create magento-public-ip

The reserved IP address can be associated to the Magento service by specifying it as the value of the service.loadBalancerIP parameter while installing the chart.

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

helm install my-release \
  --set magentoUsername=admin,magentoPassword=password,mariadb.auth.rootPassword=secretpassword \
    oci://REGISTRY_NAME/REPOSITORY_NAME/magento

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 Magento 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/magento

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

To 26.0.0

This major release bumps the and MariaDB chart version to 18.x.x; no major issues are expected during the upgrade.

To 23.0.0

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

21.0.0

This major updates the Elasticsearch subchart to its newest major, 19.0.0, which removes support for elasticsearch-curator. Check Elasticsearch Upgrading Notes for more information.

19.0.0

This major updates the Elasticsearch subchart to its newest major, 17.0.0, which adds support for X-pack security features such as SSL/TLS encryption and password protection. Check Elasticsearch Upgrading Notes for more information.

18.0.0

Elasticsearch dependency version was bumped to a new major version changing the license of some of its components to the Elastic License that is not currently accepted as an Open Source license by the Open Source Initiative (OSI). Check Elasticsearch Upgrading Notes for more information.

Regular upgrade is compatible from previous versions.

17.0.0

In this major there were three main changes introduced:

  • Parameter standarizations
  • Migration to non-root
  • Elasticsearch sub-chart 14.0.0 update

1. Chart standarizations

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

  • Lots of new parameters were added, including SMTP configuration, for using existing DBs (magentoSkipInstall), configuring security context, etc.
  • Some parameters were renamed or disappeared in favor of new ones in this major version. For example, persistence.magento.* parameters were deprecated in favor of persistence.*.
  • This version also introduces bitnami/common, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.

2. Migration of the Magento image to non-root

The Bitnami Magento image was migrated to a “non-root” user approach. Previously the container ran as the root user and the Apache daemon was started as the daemon user. From now on, both the container and the Apache daemon run as user 1001. Consequences:

  • The HTTP/HTTPS ports exposed by the container are now 8080/8443 instead of 80/443.
  • Backwards compatibility is not guaranteed. Uninstall & install the chart again to obtain the latest version.

3. Elasticsearch sub-chart 14.0.0 update

This version of the Elasticsearch sub-chart standardizes the way of defining Ingress rules in the Kibana sub-chart.

14.0.0

This version updates the docker image to 2.3.5-debian-10-r57 version. That version persists the full htdocs folder. From now on, to upgrade the Magento version it is needed to follow the official steps manually.

13.0.0

Several changes were introduced that can break backwards compatibility:

  • This version includes a new major version of the ElasticSearch chart bundled as dependency. You can find the release notes of the new ElasticSearch major version in this section of the ES README.
  • Labels are adapted to follow the Helm charts best practices.

9.0.0

This version enabled by default an initContainer that modify some kernel settings to meet the Elasticsearch requirements.

Currently, Elasticsearch requires some changes in the kernel of the host machine to work as expected. If those values are not set in the underlying operating system, the ES containers fail to boot with ERROR messages. More information about these requirements can be found in the links below:

You can disable the initContainer using the elasticsearch.sysctlImage.enabled=false parameter.

Upgrading

To 28.0.0

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 24.0.0

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 22.0.0

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 18.0.0

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

Additionally, it updates both the Elasticsearch and the MariaDB subcharts to their latest major versions, 18.0.0 and 10.0.0 respectively, where similar changes have been also performed. Check Elasticsearch Upgrading Notes and MariaDB Upgrading Notes for more information.

The following values have been renamed:

  • service.port renamed as service.ports.http.
  • service.httpsPort renamed as service.ports.https.
  • persistence.accessMode renamed as persistence.accessModes and has array type now.
  • sessionAffinity renamed as service.sessionAffinity.

To 17.0.0

To upgrade to 17.0.0, backup Magento data and the previous MariaDB databases, install a new Magento chart and import the backups and data, ensuring the 1001 user has the appropriate permissions on the migrated volume.

You can disable the non-root behavior by setting the parameters containerSecurityContext.runAsUser to root.

For the Elasticsearch 14.0.0 sub-chart update, when enabling Kibana and configuring a single hostname for the Kibana Ingress rule, set the kibana.ingress.hostname value. When defining more than one, set the kibana.ingress.extraHosts array. Apart from this case, no issues are expected to appear when upgrading.

To 16.0.0

  • Chart labels were adapted to follow the Helm charts standard labels.
  • This version also introduces bitnami/common, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.

Consequences:

  • Backwards compatibility is not guaranteed. However, you can easily workaround this issue by removing Magento deployment before upgrading (the following example assumes that the release name is magento):
export APP_HOST=$(kubectl get svc --namespace default magento --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
export APP_PASSWORD=$(kubectl get secret --namespace default magento -o jsonpath="{.data.magento-password}" | base64 -d)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default magento-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default magento-mariadb -o jsonpath="{.data.mariadb-password}" | base64 -d)
kubectl delete deployments.apps magento
helm upgrade magento oci://REGISTRY_NAME/REPOSITORY_NAME/magento --set magentoHost=$APP_HOST,magentoPassword=$APP_PASSWORD,mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD,mariadb.auth.password=$MARIADB_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.

To 15.0.0

In this major there were two main changes introduced:

  1. Adaptation to Helm v2 EOL
  2. Updated MariaDB and Elasticsearch dependency versions

Please read the update notes carefully.

1. Adaptation to Helm v2 EOL

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
  • If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the official Helm documentation about migrating from Helm v2 to v3

2. Updated MariaDB dependency version

In this major the MariaDB and Elasticsearch dependency versions were also bumped to a new major version that introduces several incompatilibites. Therefore, backwards compatibility is not guaranteed. Check MariaDB Upgrading Notes for more information. Although it is using the latest bitnami/mariadb chart, given Magento 2.4 current limitations, the container image of MariaDB has been bumped to 10.4.x instead of using the latest 10.5.x.

To upgrade to 15.0.0, it should be done reusing the PVCs used to hold data from MariaDB, Elasticsearch and Magento data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is magento and that a rootUser.password was defined for MariaDB in values.yaml when the chart was first installed):

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 10.4.x

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

export MAGENTO_HOST=$(kubectl get svc --namespace default magento --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
export MAGENTO_PASSWORD=$(kubectl get secret --namespace default magento -o jsonpath="{.data.magento-password}" | base64 -d)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default magento-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default magento-mariadb -o jsonpath="{.data.mariadb-password}" | base64 -d)
export MARIADB_PVC=$(kubectl get pvc -l app=mariadb,component=master,release=magento -o jsonpath="{.items[0].metadata.name}")

Delete the Magento deployment and delete the MariaDB statefulset. Notice the option --cascade=false in the latter.

kubectl delete deployments.apps magento
kubectl delete statefulsets.apps magento-mariadb --cascade=false

Now the upgrade works:

helm upgrade magento oci://REGISTRY_NAME/REPOSITORY_NAME/magento --set mariadb.primary.persistence.existingClaim=$MARIADB_PVC --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD --set mariadb.auth.password=$MARIADB_PASSWORD --set magentoPassword=$MAGENTO_PASSWORD --set magentoHost=$MAGENTO_HOST

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 will have to delete the existing MariaDB pod and the new statefulset is going to create a new one

kubectl delete pod magento-mariadb-0z

Finally, you should see the lines below in MariaDB container logs:

$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=magento,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 10.0.0

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 4dfac075aacf74405e31ae5b27df4369e84eb0b0 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 5.0.0

Manual intervention is needed if configuring Elasticsearch 6 as Magento search engine is desired.

Follow the Magento documentation in order to configure Elasticsearch, setting Search Engine to Elasticsearch 6.0+. If using the Elasticsearch server included in this chart, hostname and port can be obtained with the following commands:

kubectl get svc -l app=elasticsearch,component=client,release=RELEASE_NAME -o jsonpath="{.items[0].metadata.name}"
kubectl get svc -l app=elasticsearch,component=client,release=RELEASE_NAME -o jsonpath="{.items[0].spec.ports[0].port}"

Where RELEASE_NAME is the name of the release. Use helm list to find it.

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 magento:

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