Configure an existing BIND9 server for Designate¶

If you already have a running BIND9 server, you can configure and use it for the Designate deployment.

The example configuration below has three predeployed BIND9 servers.

To configure an existing BIND9 server for Designate:

1. Open your BIND9 server UI.

2. Verify that the BIND9 configuration files contain rdnc.key for Designate.

   The following text is an example of /etc/bind/named.conf.local on the managed BIND9 server with the IPs allowed for Designate and rdnc.key:

   key "designate" {
     algorithm hmac-sha512;
     secret "4pc+X4PDqb2q+5o72dISm72LM1Ds9X2EYZjqg+nmsS7F/C8H+z0fLLBunoitw==";
   };
   controls {
     inet 10.0.0.3 port 953
     allow {
        172.16.10.101;
        172.16.10.102;
        172.16.10.103;
     }
     keys {
       designate;
     };
   };
   

3. Open classes/cluster/cluster_name/openstack in your Git project repository.

4. In init.yml, add the following parameters:

   bind9_node01_address: 10.0.0.1
   bind9_node02_address: 10.0.0.2
   bind9_node03_address: 10.0.0.3
   mysql_designate_password: password
   keystone_designate_password: password
   designate_service_host: ${_param:openstack_control_address}
   designate_bind9_rndc_algorithm: hmac-sha512
   designate_bind9_rndc_key: >
     4pc+X4PDqb2q+5o72dISm72LM1Ds9X2EYZjqg+nmsS7F/C8H+z0fLLBunoitw==
   designate_domain_id: 5186883b-91fb-4891-bd49-e6769234a8fc
   designate_pool_ns_records:
     - hostname: 'ns1.example.org.'
       priority: 10
   designate_pool_nameservers:
     - host: ${_param:bind9_node01_address}
       port: 53
     - host: ${_param:bind9_node02_address}
       port: 53
     - host: ${_param:bind9_node03_address}
       port: 53
   designate_pool_target_type: bind9
   designate_pool_target_masters:
     - host: ${_param:openstack_control_node01_address}
       port: 5354
     - host: ${_param:openstack_control_node02_address}
       port: 5354
     - host: ${_param:openstack_control_node03_address}
       port: 5354
   designate_pool_target_options:
     host: ${_param:bind9_node01_address}
     port: 53
     rndc_host: ${_param:bind9_node01_address}
     rndc_port: 953
     rndc_key_file: /etc/designate/rndc.key
   designate_version: ${_param:openstack_version}
   

5. In control.yml, modify the parameters section. Add targets according to the number of BIND9 severs that will be managed, three in our case.

   Example:

   designate:
       server:
         backend:
           bind9:
             rndc_key: ${_param:designate_bind9_rndc_key}
             rndc_algorithm: ${_param:designate_bind9_rndc_algorithm}
         pools:
           default:
             description: 'test pool'
             targets:
               default:
                 description: 'test target1'
               default1:
                 type: ${_param:designate_pool_target_type}
                 description: 'test target2'
                  masters: ${_param:designate_pool_target_masters}
                 options:
                   host: ${_param:bind9_node02_address}
                   port: 53
                   rndc_host: ${_param:bind9_node02_address}
                   rndc_port: 953
                   rndc_key_file: /etc/designate/rndc.key
               default2:
                 type: ${_param:designate_pool_target_type}
                 description: 'test target3'
                  masters: ${_param:designate_pool_target_masters}
                 options:
                   host: ${_param:bind9_node03_address}
                   port: 53
                   rndc_host: ${_param:bind9_node03_address}
                   rndc_port: 953
                   rndc_key_file: /etc/designate/rndc.key
   

6. Add your changes to a new commit.

7. Commit and push the changes.

Once done, proceed to deploy Designate as described in Deploy Designate.
