# PrestaShop

[PrestaShop](https://prestashop.com/) is a popular open source e-commerce solution. Professional tools are easily accessible to increase online sales including instant guest checkout, abandoned cart reminders and automated Email marketing.

## TL;DR

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

## Introduction

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

It also packages the [Bitnami MariaDB chart](https://github.com/kubernetes/charts/tree/master/bitnami/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the PrestaShop application.

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 2.12+ 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/prestashop
```

The command deploys PrestaShop 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 PrestaShop chart and their default values per section/component:

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

> **Note**:
>
> For PrestaShop to function correctly, you should specify the `prestashopHost` parameter to specify the FQDN (recommended) or the public IP address of the PrestaShop service.
>
> Optionally, you can specify the `prestashopLoadBalancerIP` parameter to assign a reserved IP address to the PrestaShop 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 prestashop-public-ip
> ```
>
> The reserved IP address can be associated to the PrestaShop service by specifying it as the value of the `prestashopLoadBalancerIP` 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 prestashopUsername=admin,prestashopPassword=password,mariadb.auth.rootPassword=secretpassword \
    bitnami/prestashop
```

The above command sets the PrestaShop administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MariaDB `root` user password to `secretpassword`.

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/prestashop
```

> **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.

### 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.
1. 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
```

1. Install the chart

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` paremeter. Find more infomation 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/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

## Persistence

The [Bitnami PrestaShop](https://github.com/bitnami/bitnami-docker-prestashop) image stores the PrestaShop data and configurations at the `/bitnami/prestashop` 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
1. Create the PersistentVolumeClaim
1. Install the chart

```bash
$ helm install my-release --set persistence.existingClaim=PVC_NAME bitnami/prestashop
```

### 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://github.com/kubernetes/minikube/blob/master/docs/host_folder_mount.md) 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).
1. Install the chart

    ```bash
    $ helm install my-release --set persistence.hostPath=/PATH/TO/HOST/MOUNT bitnami/prestashop
    ```

    This will mount the `prestashop-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.
1. Because the container cannot control the host machine's directory permissions, you must set the PrestaShop file directory permissions yourself and disable or clear PrestaShop cache.

## Troubleshooting

### SSL

One needs to explicitly turn on SSL in the Prestashop administration panel, else a `302` redirect to `http` scheme is returned on any page of the site by default.

To enable SSL on all pages, follow these steps:

- Browse to the administration panel and log in.
- Click “Shop Parameters” in the left navigation panel.
- Set the option “Enable SSL” to “Yes”.
- Click the “Save” button.
- Set the (now enabled) option “Enable SSL on all pages” to “Yes”.
- Click the “Save” button.

## Upgrading

### To 11.0.0

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](https://github.com/bitnami/charts/tree/master/bitnami/mariadb#to-800) for more information.

To upgrade to `11.0.0`, you have two alternatives:

- Install a new Prestashop chart, and migrate your Prestashop site using backup/restore using any [Backup and Restore tool from Prestashop marketplace](https://addons.prestashop.com/en/search?search_query=backup&).
- Reuse the PVC used to hold the MariaDB data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is `prestashop`):

Obtain the credentials and the name of the PVC used to hold the MariaDB data on your current release:

```console
export PRESTASHOP_PASSWORD=$(kubectl get secret --namespace default prestashop -o jsonpath="{.data.prestashop-password}" | base64 --decode)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default prestashop-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 --decode)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default prestashop-mariadb -o jsonpath="{.data.mariadb-password}" | base64 --decode)
export MARIADB_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=prestashop,app.kubernetes.io/name=mariadb,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
```

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

```console
$ helm upgrade prestashop bitnami/prestashop --set prestashopPassword=$PRESTASHOP_PASSWORD --set replicaCount=0 --set mariadb.enabled=false --version 10.0.0
```

Finally, upgrade you release to 11.0.0 reusing the existing PVC, and enabling back MariaDB:

```console
$ helm upgrade prestashop bitnami/prestashop --set mariadb.primary.persistence.existingClaim=$MARIADB_PVC --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD --set mariadb.auth.password=$MARIADB_PASSWORD --set prestashopPassword=$PRESTASHOP_PASSWORD
```

You should see the lines below in MariaDB container logs:

```console
$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=prestashop,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

The [Bitnami PrestaShop](https://github.com/bitnami/bitnami-docker-prestashop) image was updated to support and enable the "non-root" user approach

If you want to continue to run the container image as the `root` user, you need to set `podSecurityContext.enabled=false` and `containerSecurity.context.enabled=false`.

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

### To 9.0.0

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/17308 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 prestashop:

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