⁠ TL;DR

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

⁠ Introduction

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

⁠ Before you begin

• 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/parse

The command deploys Parse on the Kubernetes cluster in the default configuration. The Parameters⁠ section lists the parameters that can be configured during installation.

⁠ Configuration and installation details

This section describes credentials, configuration, and other installation options.

⁠ 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.

⁠ 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.

⁠ Deploy your Cloud functions with Parse Cloud Code

The Bitnami Parse⁠ image allows you to deploy your Cloud functions with Parse Cloud Code (a feature which allows running a piece of code in your Parse Server instead of the user's mobile devices). In order to add your custom scripts, they must be located inside the chart folder files/cloud so they can be consumed as a ConfigMap.

Alternatively, you can specify custom scripts using the cloudCodeScripts parameter as dict.

In addition to these options, you can also set an external ConfigMap with all the Cloud Code scripts. This is done by setting the existingCloudCodeScriptsCM parameter. Note that this will override the two previous options.

⁠ Gateway API

This chart provides support for exposing Parse using the Gateway API⁠ and its HTTPRoute resource. If you have a Gateway controller installed on your cluster, such as APISIX, Contour, Envoy Gateway, NGINX Gateway Fabric or Kong Ingress Controller you can utilize the Gateway controller to serve your application. To enable Gateway API integration, set XXX.httpRoute.enabled to true (where XXX is server, or dashboard depending on which component you want to expose). The Gateway to be used can be customized by setting the XXX.httpRoute.parentRefs parameter. By default, it will reference a Gateway named gateway in the same namespace as the release.

You can specify the list of hostnames to be mapped to the deployment using the XXX.httpRoute.hostnames parameter. Additionally, you can customize the rules used to route the traffic to the service by modifying the XXX.httpRoute.matches and XXX.httpRoute.filters parameters or adding new rules using the XXX.httpRoute.extraRules parameter.

⁠ 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, set ingress.enabled to true.

The most common scenario is to have one host name mapped to the deployment. In this case, the ingress.hostname property can be used to set the host name. The ingress.tls parameter can be used to add the TLS configuration for this host.

However, it is also possible to have more than one host. To facilitate this, the ingress.extraHosts parameter (if available) can be set with the host names specified as an array. The ingress.extraTLS parameter (if available) can also be used to add the TLS configuration for extra hosts.

Adding the TLS parameter (where available) will cause the chart to generate HTTPS URLs, and the application will be available on port 443. The actual TLS secrets do not have to be generated by this chart. However, if TLS is enabled, the Ingress record will not work until the TLS secret exists.

⁠ FIPS parameters

The FIPS parameters only have effect if you are using images from the Bitnami Secure Images catalog⁠.

For more information on this new support, please refer to the FIPS Compliance section⁠.

⁠ 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.

⁠ 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 (available in the server and dashboard sections) property.

extraEnvVars:
  - name: PARSE_SERVER_ALLOW_CLIENT_CLASS_CREATION
    value: true

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

⁠ 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, MASTER_KEY and PARSE_DASHBOARD_PASSWORD placeholders)

kubectl create secret generic SECRET_NAME --from-literal=master-key=PASSWORD --from-literal=parse-dashboard-password=PARSE_DASHBOARD_PASSWORD --dry-run -o yaml | kubectl apply -f -

⁠ Deploying extra resources

There are cases where you may want to deploy extra objects, such as KongPlugins, KongConsumers, amongst others. For covering this case, the chart allows adding the full specification of other objects using the extraDeploy parameter. The following example would activate a plugin at deployment time.

## <a id="extra-objects-to-deploy-value"></a> Extra objects to deploy (value evaluated as a template)
##
extraDeploy: |-
  - apiVersion: rbac.authorization.k8s.io/v1
    kind: RoleBinding
    metadata:
      name: {{ include "common.names.fullname" . }}-privileged
      namespace: {{ .Release.Namespace }}
      labels: {{- include "common.labels.standard" ( dict "customLabels" .Values.commonLabels "context" $ ) | nindent 6 }}
    roleRef:
      apiGroup: rbac.authorization.k8s.io
      kind: ClusterRole
      name: cluster-admin
    subjects:
      - kind: ServiceAccount
        name: default
        namespace: {{ .Release.Namespace }}

⁠ Setting Pod's affinity

This chart allows you to set your custom affinity using the XXX.affinity parameter(s). Find more information 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 XXX.podAffinityPreset, XXX.podAntiAffinityPreset, or XXX.nodeAffinityPreset parameters.

⁠ Persistence

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

⁠ Adjust permissions of persistent volume mountpoint

As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.

By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions. As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.

You can enable this initContainer by setting volumePermissions.enabled to true.
