# Parse

[Parse](https://parse.com/) is an open source version of the Parse backend that can be deployed to any infrastructure that can run Node.js.

## TL;DR;

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/parse
```

## Introduction

This chart bootstraps a [Parse](https://github.com/bitnami/bitnami-docker-parse) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) 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](https://kubeprod.io/).

## Prerequisites

- 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`:

```console
$ helm install my-release bitnami/parse
```

The command deploys Parse 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`

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
$ helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

## Parameters

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

The above parameters map to the env variables defined in [bitnami/parse](http://github.com/bitnami/bitnami-docker-parse). For more information please refer to the [bitnami/parse](http://github.com/bitnami/bitnami-docker-parse) image documentation.

> **Note**:
>
> For the Parse application function correctly, you should specify the `parseHost` parameter to specify the FQDN (recommended) or the public IP address of the Parse service.
>
> Optionally, you can specify the `loadBalancerIP` parameter to assign a reserved IP address to the Parse 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:
>
> ```bash
> $ gcloud compute addresses create parse-public-ip
> ```
>
> The reserved IP address can be associated to the Parse service by specifying it as the value of the `loadBalancerIP` parameter while installing the chart.

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

```console
$ helm install my-release \
  --set dashboard.username=admin,dashboard.password=password \
    bitnami/parse
```

The above command sets the Parse administrator account username and password to `admin` and `password` respectively.

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 bitnami/parse
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

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](https://github.com/bitnami/bitnami-docker-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.

## Persistence

The [Bitnami Parse](https://github.com/bitnami/bitnami-docker-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](#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`.

### 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.

```yaml
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.

## Upgrading

### To 10.0.0

Backwards compatibility is not guaranteed. The following notables changes were included:

- **parse-dashboard** is bumped to the branch 2 (major version)
- Labels are adapted to follow the Helm charts best practices.

### To 5.1.0

Parse & Parse Dashboard containers were moved to a non-root approach. There shouldn't be any issue when upgrading since the corresponding `securityContext` is enabled by default. Both container images and chart can be upgraded by running the command below:

```
$ helm upgrade my-release bitnami/parse
```

If you use a previous container image (previous to **3.1.2-r14** for Parse or **1.2.0-r69** for Parse Dashboard), disable the `securityContext` by running the command below:

```
$ helm upgrade my-release bitnami/parse --set server.securityContext.enabled=false,dashboard.securityContext.enabled=false,server.image.tag=XXX,dashboard.image.tag=YYY
```

### 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 parse:

```console
$ kubectl patch deployment parse-parse-dashboard --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
$ kubectl patch deployment parse-parse-server --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
$ kubectl patch deployment parse-mongodb --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
```
