ownCloud

ownCloud is a file sharing server that puts the control and security of your own data back into your hands.

This Helm chart is deprecated

Given the stable deprecation timeline, the Bitnami maintained ownCloud Helm chart is now located at bitnami/charts.

The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we’ve been keeping here these years. Installation instructions are very similar, just adding the bitnami repo and using it during the installation (bitnami/<chart> instead of stable/<chart>)

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/<chart>           # Helm 3
$ helm install --name my-release bitnami/<chart>    # Helm 2

To update an exisiting stable deployment with a chart hosted in the bitnami repository you can execute

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm upgrade my-release bitnami/<chart>

Issues and PRs related to the chart itself will be redirected to bitnami/charts GitHub repository. In the same way, we’ll be happy to answer questions related to this migration process in this issue created as a common place for discussion.

TL;DR;

$ helm install my-release stable/owncloud

Introduction

This chart bootstraps an ownCloud 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 for the database requirements of the ownCloud application.

Bitnami charts can be used with Kubeapps 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.

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:

$ helm install my-release stable/owncloud

The command deploys ownCloud 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

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

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

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

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

Note:

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

Optionally, you can specify the owncloudLoadBalancerIP parameter to assign a reserved IP address to the ownCloud 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 owncloud-public-ip
> ```
>
> The reserved IP address can be associated to the ownCloud service by specifying it as the value of the `owncloudLoadBalancerIP` 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 owncloudUsername=admin,owncloudPassword=password,mariadb.mariadbRootPassword=secretpassword \
    stable/owncloud

The above command sets the ownCloud 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,

$ helm install my-release -f values.yaml stable/owncloud

Tip: You can use the default values.yaml

Configuration and installation details

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.

Persistence

The Bitnami ownCloud image stores the ownCloud data and configurations at the /bitnami/owncloud path 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.

Upgrading

7.0.0

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/17304 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 owncloud:

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