# Nextcloud + Onlyoffice helm chart
This helm chart installs Nextcloud and ONLYOFFICE
and configures Nextcloud to use ONLYOFFICE as its document editor.
Depends on the
[Nextcloud](https://github.com/nextcloud/helm/tree/master/charts/nextcloud)
chart.
For configuration details on Nextcloud, refer to their documentation.
Parts of this chart are based on a copy of the
[COLLABORA code helm chart](https://github.com/helm/charts/tree/master/stable/collabora-code)
**NOTE:** The `onlyoffice.server_name` variable needs to be
overwritten with a URL that points to your onlyoffice for this to work
correctly.
See `values-local.yaml.example` for an example of domain configurations
you might want to do.
These instructions assume you copy `values-local.yaml.example` to `values-local.yaml`
and edit it.
**NOTE:** It is very important that you uncomment and set the following password and
secrets variables manually when you run helm install:
- `nextcloud.nextcloud.password`
- `nextcloud.mariadb.auth.password`
- `nextcloud.mariadb.auth.rootPassword`
- `redis.auth.password`
- `rabbitmq.auth.password`
- `rabbitmq.auth.erlangCookie`
- `global.onlyofficeDb.password`
**NOTE:** The chart currently includes a ConfigMap with a name that is not
dependent on the release name. This means that the chart cannot be installed
more than once into the same namespace. If you need to install Nextcloud and
Onlyoffice several times into the same cluster, use different namespaces.
### Install from the remote repo
This is the way to go if you want to use the packaged chart as is. If you'd like to make changes before installing, refer to the next section.
Add our helm repository[^1]:
helm repo add nextcloud-onlyoffice https://open.greenhost.net/api/v4/projects/1/packages/helm/stable
```
Then install the chart:
```console
helm install -f values-local.yaml my-nextcloud nextcloud-onlyoffice/nextcloud-onlyoffice
```
### Install from a local repo
Start by cloning the nextcloud helm chart repo:
```console
git clone https://open.greenhost.net/stackspin/nextcloud.git
```
Add the dependencies repositories:
```console
# nextcloud chart
helm repo add nextcloud https://nextcloud.github.io/helm
# rabbitmq chart
helm repo add bitnami https://charts.bitnami.com/bitnami
```
Fetch the chart dependencies:
```console
helm dependency build
```
Then install the chart:
helm install -f values-local.yaml my-nextcloud .
## Nextcloud configuration.
This chart adds a "postStart" command to the Nextcloud pod, that installs apps
(see below) and applies a custom configuration to set up those apps and
integration with ONLYOFFICE as well as the Stackspin OIDC provider.
Kubernetes postStart commands do not log to the pod log.
Instead, the script creates its own log in `/var/www/tmp/postStart<date>.log`.
This means that even if you can't `exec` into the pod (because something is failing),
you can see the logs inside the `data` folder in the PVC.
Often, if the `postStart` command fails,
you can also see the problem by running `kubectl describe pod <nextcloud pod>`.
## Apps
The Nextcloud app store allows admin users to install applications, many of
which have not undergone security testing.
For that reason we disabled downloading new apps via the app store.
Upon installing Nextcloud it is possible to specify
which applications from the app store are available.
It is also possible to enable them by default.
Apps that are not enabled by default can be enabled by admins
through the Apps screen in Nextcloud.

Apps that are installed this way are automatically updated to their newest
version every time Nextcloud is updated.
To install apps, edit the values.yaml file:
```yaml
apps:
- name: sociallogin # Installs sociallogin app
enabled: false # Disables sociallogin by default
```
Note that manually enabled apps will not be disabled upon rerunning the installer,
which can lead to incompatibility errors upon Nextcloud Server version upgrades.
Check for `postStart` errors as mentioned above.
Additionally, we have added an option to install Apps immediately from GitHub releases.
Unlike when installing them with `occ`,
this allows us to pin the versions to specific GitHub releases.
To install an app from GitHub releases:
Maarten de Waard
committed
```yaml
apps:
- name: onlyoffice
# The name of the repository. This is the name for a repository located at
# https://github.com/ONLYOFFICE/onlyoffice-nextcloud:
github_repository: ONLYOFFICE/onlyoffice-nextcloud
# The version to install or upgrade the app to
version: 7.5.4
# The name of the "asset" to download from this release. This name can be
# found on https://github.com/ONLYOFFICE/onlyoffice-nextcloud/releases
release_filename: onlyoffice.tar.gz
# Enable the app after installing it
enabled: true
```
## Values
The included `values.yaml` file configures Nextcloud to use a Mariadb database,
otherwise the Job cannot access the database for plugin installation.
It also configures NextCloud to use a persistent volume, because this is
necessary for the integration job to work. Be sure to change the size of the
persistent disk (default: 2 GB) if you need more.

This chart comes with [Cypress e2e tests](https://www.cypress.io/) that you can
run by running `helm test <release name>`. Add the `--logs` parameter if you
want to immediately see the console output from the test.
If the tests fail, you'll want to observe the steps Cypress executes in the
browser. To do so, install Cypress with `npm`
#### Setup
```console
npm install -D
#### Usage
Export KUBECONFIG to access a cluster with an existing nextcloud helm chart installation.
```console
export KUBECONFIG=…/kube_config_cluster.yml
Set environment variables to use with Cypress. Read the script to see the
possible values and adjust them if necessary.
```console
source get-cypress-vars.sh <release_name>
```
Start Cypress GUI:
```console
./node_modules/.bin/cypress open
```
or just run the tests from the console:
```console
./node_modules/.bin/cypress run --headed
```
[^1]: If you want to test a version that is not on the `main` branch yet, use `https://open.greenhost.net/api/v4/projects/1/packages/helm/unstable`
## Releasing
To publish a new version of the helm chart:
1. increase the chart version in `Chart.yaml`;
2. update the appVersion (including both nextcloud and onlyoffice) in Chart.yaml;
3. update `CHANGELOG.md` and check that it includes relevant changes, including
4. commit and push these changes to `main`;
5. create a new git tag for the new release and push it to gitlab as well.
The last step will trigger a CI run that will package and publish the helm chart.
