The following procedure describes how to redeploy an existing Distributed DDNS Service Node on a BlueCat DNS/DHCP Server (BDDS).

To redeploy the Distributed DDNS Service Node on BDDS:
  1. Before you begin, remove the running container on the Service Node. To do so, on the host server of the Database Node, run the following command: 
    docker rm –f <running-container-name>

  2. Log in to the BlueCat instance for the Distributed DDNS Application Node.

  3. Under Available Actions, click Distributed DDNS, then click the DDNS Deployment tab.

  4. Within the list of BDDS servers, click the name of the server whose service node you want to redeploy.

  5. In the Service Type section, select DDNS Node.

    If a DDNS Node is already deployed, you will be warned that a DDNS Node is already enabled, and that the service will be re-deployed (rather than deployed to that node for the first time).

  6. Click Continue.

  7. In the General section, enter the following information:

    • Authentication Type: Select the method of authentication. You can select Password or SSH Key.

      If you select Password, enter the following information:

      • SSH Username: Enter the username that will be used to SSH to the BDDS.

      • SSH Password: Enter the password that will be used to SSH to the BDDS.

      If you select SSH Key, enter the following information:

      • SSH Username: Enter the username of the root or non-root user. If entering a non-root username, it must also be added to the /etc/sudoers file. You can use the following commands to add non-root username to the file:

        sudo visudo
<non-root_username> ALL=(ALL) NOPASSWD: ALL

      • SSH Private Key—enter the SSH private key produced using the ssh-keygen command. Ensure that the corresponding public key is available on the destination server using the following commands:

        ssh-keygen
ssh-copy-id -i <public_key_file> <remote_user>@<remote_server>

      • Key Passphrase: Enter the key passphrase if one was used when generating the SSH key pair.

    • DB Address: Select one of the IP addresses of the available Data Nodes.

    • DB Password: Enter the password for the default user of the database cluster. By default, the password is ddns_admin.

  8. In the Repository section, enter the following information:

    • Image: Enter quay.io/bluecat/distributed_ddns_service:23.2.3

    • Username: Enter your Quay username.

    • Password: Enter your Quay password.

  9. Click Deploy.
