= Nextcoloud Appliance

== Server setup

Copy your ssh key to the server for the root user

```
workstation $ ssh-copy-id root@server_ip
```

== Ansible Playbooks

Use the ansible playbooks to setup the nextcloud appliance

```
workstation $ ansible-playbook -i inventory_source, ansible/nextcloud_bootstrap.yaml

```

Debian 10 needs the Python interpreter setup by setting `-e ansible_python_interpreter=/usr/bin/python3` or in the inventory file.

This example runs the playbook with debugging information, for a specific host, and the Python interpreter.

```
workstation $ ansible-playbook -vvv -u root -i 192.168.1.112, -e ansible_python_interpreter=/usr/bin/python3 nextcloud_appliance.yaml
```



=== Parameters

There are multiple variables that can be set to customize the nextcloud installation.

* *To set the Nextcloud instance domain name set the `nextcloud_domain_name` variable*

```
workstation $ ansible-playbook -vvv -u root -i 192.168.1.112, -e nextcloud_domain_name="nextcloud.example.com" nextcloud_appliance.yaml
```

== Collabora Office Load Balance

Collabora uses the WOPI procotol. This protocol can be balanced by using the `WOPISrc` to send the traffic to the proper loolwsd
server.

Disable SSL of the loolwsd web service.

==== loolwsd.xml

```
<enable default="true" desc="Controls whether SSL encryption between browser and loolwsd is enabled (do not disable for production deployment). If default is false, must first be compiled with SSL support to enable." type="bool">false</enable>
 
<termination default="false" desc="Connection via proxy where loolwsd acts as working via https, but actually uses http." type="bool">true</termination>
```

==== HAProxy

Configure HAProxy to extract the `WOPISrc` URL parameter and use it to send always the traffic to the same `loolwsd` backend.

```
Frontend loolwsdbind \*:443 ssl crt /Path to your certificate_and_key.pem
  http-request set-header X-HAProxy-loolwsd %[url_param(WOPISrc)]
  mode http 
  default_backend loolwsd 
  
backend loolwsd timeout tunnel 3600s 
  mode http 
  balance hdr(X-HAProxy-loolwsd) 
  server lool1 <CE Server 1 IP>:9980 
  server lool2 <CE Server 2 IP>:9980 
  server lool3 <CE Server 3 IP>:99
```
