Overview

This is a Juju charm, which allows deployment and scaling of the Bono component of a Project Clearwater IMS core.

Bono should only be deployed alongside the other Project Clearwater charms and a DNS server - see our main Juju README for instructions on this, including a bundle that makes this deployment simple.

Deployment

Initial deployment

The Bono service should be initially deployed as part of a Clearwater bundle, following the instructions in our main README.

Note that the clearwater-bono charm can only be deployed on the amd64 architecture (although the provided bundle already enforces this constraint).

Scale out Usage

clearwater-bono can be scaled up through the normal Juju mechanism of juju add-unit clearwater-bono.

This will create a new Bono instance, and trigger the DNS server charm to add a DNS record for this Bono. (Unlike Sprout, Homestead, Homer and Ralf nodes, Bono nodes don't have a shared datastore, so don't need any cluster configuration.)

Using Bono

Once installed, Bono will listen for SIP traffic on port 5060 (both TCP and UDP). Once you have created a SIP subscriber through the Ellis UI, you can use a standard SIP client (e.g. Blink, Boghe or X-Lite) to register against Bono's public IP (which you can find with juju status clearwater-bono) and make calls.

Our "Making your first call" documentation has more information on this process.

Configuration

• zone: The home domain of this IMS deployment - this could be a real domain that you own, or an internal-only name like "clearwater.local".
• repo: The URL of the Clearwater package repository server. Our latest relese, updated roughly every two weeks, is at http://repo.cw-ngv.com/juju-clearwater-2.
• sas: (optional) The location of a Metaswitch SAS server for diagnostics and call flows.
• trusted_peers: (optional) Comma-separated list of IP addresses of trusted peers, for when Bono is used as an IBCF rather than a P-CSCF.

The zone, sas and repo configuration options should be consistent across all Clearwater nodes in the deployment.

Files downloaded

When the charm is being installed, several files are downloaded:

• Our standard Chef setup scripts, checked out from https://github.com/Metaswitch/chef.
• The Bono Debian packages, from our package repository server at repo.cw-ngv.com.
• Any dependencies of those Debian packages, from the standard Ubuntu repository servers.
