## Containerized

Use environment variables to inform Nextcloud about internal configuration:

| Name                        | Default   | Description                                               |
|-----------------------------|-----------|-----------------------------------------------------------|
| `NEXTCLOUD_ADMIN_USER`      | (not set) | Name of the Nextcloud admin user                          |
| `NEXTCLOUD_ADMIN_PASSWORD`  | (not set) | Password for the Nextcloud admin user                     |
| `NEXTCLOUD_TRUSTED_DOMAINS` | (not set) | Optional space-separated list of domains                  |
| `REDIS_HOST`                | (not set) | Name of the Redis container, or FQDN of the Redis service |
| `REDIS_HOST_PORT`           | 6379      | Port for Redis services that run on non-standard ports    |

### Official helm chart

Installation:

1. add the repository to helm

   ```sh
   helm repo add nextcloud https://nextcloud.github.io/helm/
   helm repo update
   ```

1. get the default values from the updated chart

   ```sh
   helm inspect values nextcloud/nextcloud > "$(git rev-parse --show-toplevel)/kubernetes/helm/nextcloud/values.yaml"
   ```

1. edit the values to your heart's content
1. install the server

   ```sh
   helm install --namespace nextcloud nextcloud nextcloud/nextcloud --values kubernetes/helm/nextcloud/values.dev.yaml
   helm install --atomic --create-namespace --namespace nextcloud nextcloud nextcloud/nextcloud --values kubernetes/helm/nextcloud/values.dev.yaml
   ```

Update the release after changes are made to the values:

```sh
helm upgrade --atomic --namespace nextcloud nextcloud nextcloud/nextcloud --values kubernetes/helm/nextcloud/values.dev.yaml
```

Connect to the server (install with default values):

```sh
export POD_NAME=$(kubectl get pods --namespace nextcloud -l "app.kubernetes.io/name=nextcloud,app.kubernetes.io/instance=nextcloud" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace nextcloud port-forward "${POD_NAME}" 8080:80
```

default admin user: `admin`
default admin password: `changeme`

Update the external database connection parameters (install with default values):

```sh
export APP_HOST=127.0.0.1
export APP_PASSWORD=$(kubectl get secret --namespace nextcloud nextcloud -o jsonpath="{.data.nextcloud-password}" | base64 --decode)
helm upgrade nextcloud nextcloud/nextcloud \
  --set nextcloud.password=$APP_PASSWORD,nextcloud.host=$APP_HOST,service.type=ClusterIP,mariadb.enabled=false,externalDatabase.user=nextcloud,externalDatabase.database=nextcloud,externalDatabase.host=YOUR_EXTERNAL_DATABASE_HOST
```

Delete everything:

```sh
helm delete --namespace nextcloud nextcloud
kubectl delete namespace --ignore-not-found nextcloud
```

## Snappy

To configure Nextcloud from `snap`:

- use `nextcloud.occ`
- edit `/var/snap/nextcloud/current/nextcloud/config/config.php`
- use the extra configuration options via the `snap set` command
