Daniel Schreiber c46556e1f6 Allow BBB to run behind a proxy the avoid gUM permission queries per node
The idea is to run a loadbalancer node which maps each BBB node to a
path. That way each user gets only one gUM permission query for a
cluster. The loadbalancer node only serves the html5 client, each BBB
node will serve its own API and handle the websockets for freeswitch and
bbb-webrtc-sfu.

Configuring a cluster setup
===========================

* let bbb-lb.example.com be the loadbalancer node
* let bbb-01.eaxmple.com be a BBB node

Loadbalancer
------------

On the loadbalancer node add an nginx configuration similar to this one
for each BBB node:

```
location /bbb-01/html5client/ {
  proxy_pass https://bbb-01.example.com/bbb-01/html5client/;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "Upgrade";
}

```

BBB Node
--------

On the BBB node add the following options to
`/etc/bigbluebutton/bbb-web.properties`:

```
defaultHTML5ClientUrl=https://bbb-lb.example.com/bbb-01/html5client/join
presentationBaseURL=https://bbb-01.example.com/bigbluebutton/presentation
accessControlAllowOrigin=https://bbb-lb.example.com
```

Add the following options to `/etc/bigbluebutton/bbb-html5.yml`:

```
public:
  app:
    basename: '/bbb-01/html5client'
    bbbWebBase: 'https://bbb-01.eaxmple.com/bigbluebutton'
    learningDashboardBase: 'https://bbb-01.eaxmple.com/learning-dashboard'
  media:
    stunTurnServersFetchAddress: 'https://bbb-01.eaxmple.com/bigbluebutton/api/stuns'
    sip_ws_host: 'bbb-01.eaxmple.com'
  presentation:
    uploadEndpoint: 'https://bbb-01.eaxmple.com/bigbluebutton/presentation/upload'
```

Create the following unit file overrides:

* `/etc/systemd/system/bbb-html5-frontend@.service.d/cluster.conf`
* `/etc/systemd/system/bbb-html5-backend@.service.d/cluster.conf`

with the following content:

```
[Service]
Environment=ROOT_URL=https://127.0.0.1/bbb-01/html5client
```

Change the nginx `$bbb_loadbalancer_node` variable to the name of the
load balancer node in `/etc/bigbluebutton/nginx/loadbalancer.nginx` to
allow CORS requests:

```
set $bbb_loadbalancer_node https://bbb-lb.example.com
```

Prepend the mount point of bbb-html5 in all location sections except
from the `location @html5client` section in
`/etc/bigbluebutton/nginx/bbb-html5.nginx`

```
location @html5client {
    ...
}
location /bbb-01/html5client/locales {
    ...
}
```
