Updates DNS records for Clearwater using AWS Route53 service
- miscellaneous ›
This charm supports deployment of the AWS Route53 DNS agent for installing Project Clearwater in AWS EC2. See http://www.projectclearwater.org for more information on Project Clearwater.
The Clearwater Route53 service should be deployed as part of a Clearwater system. A Clearwater system can be deployed in a Juju environment by creating a config.yaml file then running the following commands.
juju deploy --config config.yaml clearwater-route53 juju deploy --config config.yaml clearwater-ellis juju deploy --config config.yaml clearwater-bono juju deploy --config config.yaml clearwater-sprout juju deploy --config config.yaml clearwater-homestead juju deploy --config config.yaml clearwater-homer juju add-relation clearwater-ellis clearwater-route53:register-ellis juju add-relation clearwater-bono clearwater-route53:register-bono juju add-relation clearwater-sprout clearwater-route53:register-sprout juju add-relation clearwater-homestead clearwater-route53:register-homestead juju add-relation clearwater-homer clearwater-route53:register-homer juju expose clearwater-bono juju expose clearwater-ellis
The config.yaml configuration file takes the following format.
clearwater-route53: zone: <domain> access_key: <ec2 access key> secret_key: <ec2 secret access key> sas: "0.0.0.0" clearwater-ellis: smtp_server: smtp.cw-ngv.com smtp_username: username smtp_password: password email_sender: firstname.lastname@example.org<mailto:email@example.com> signup_key: secret base_number: "6505550000" number_count: 1000 repo: http://repo.cw-ngv.com/stable clearwater-bono: turn_workaround: password repo: http://repo.cw-ngv.com/stable clearwater-sprout: reg_min_expires: 400 session_max_expires: 900 repo: http://repo.cw-ngv.com/stable clearwater-homestead: repo: http://repo.cw-ngv.com/stable clearwater-homer: repo: http://repo.cw-ngv.com/stable
Scale out Usage
clearwater-route53 does not current support scaling out.
Known Limitations and Issues
The only currently supported DNS service for Clearwater is clearwater-route53 (when deploying in Amazon EC2), so will currently only work on EC2. Additional DNS services will be added for other environments in future.
Note that this charm does not current pass charm proof because its hooks use EC2 APIs directly to obtain the public IP address rather than unit-get public-address. This is to work around what looks like a Juju bug - unit-get public-address on EC2 returns the public hostname of the unit rather than the public IP address. Unfortunately EC2 public hostname are actually split horizon hostnames, so if you attempt to resolve the hostname from within EC2 it actually resolved to a private IP address - it will only resolve to a public address if resolved from outside EC2.
Clearwater has a number of configuration fields which are non-defaultable. These are as follows.
zone:This must be set to a DNS zone name which is managed by the AWS Route53 service.
secret_key:These must be set to the AWS access key and secret key of the AWS account which owns the DNS zone name.
signup_key:This is used as a signup key on the Ellis self-provisioning portal, so should be set to a unique string for each installation.
number_count:These define the telephone number range assigned to the Clearwater system.
