How to Install Designate on POP! OS Latest

Designate is a DNSaaS (DNS as a service) project, which provides DNS management features for OpenStack environments. In this tutorial, we will guide you through the steps to install Designate on POP! OS Latest.

Prerequisites

  • A running POP! OS Latest instance or virtual machine with sudo access
  • Basic knowledge of POP! OS and OpenStack

Step 1: Installing Dependencies

The first step is to install the required software packages and dependencies for Designate. Open a terminal window and run the following command:

sudo apt-get update
sudo apt-get install -y designate designate-central designate-api designate-mdns designate-sink python-designateclient

Step 2: Configuring Designate

Next, you need to configure Designate by editing its configuration file. Run the following command to open the file in nano text editor:

sudo nano /etc/designate/designate.conf

In the configuration file, make the following changes:

  1. Under the [service:api] section, change the auth_strategy parameter to keystone.
  2. Under the [service:central] section, change the auth_strategy parameter to keystone.
  3. Under the [keystone_authtoken] section, add the following parameters:
auth_uri = http://<KEYSTONE_IP_ADDRESS>:5000
auth_url = http://<KEYSTONE_IP_ADDRESS>:35357
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = designate
password = <DESIGNATE_SERVICE_PASSWORD>

Note: Replace the <KEYSTONE_IP_ADDRESS> and <DESIGNATE_SERVICE_PASSWORD> placeholders with your own values.

  1. Save the changes and exit the configuration file.

Step 3: Creating the Designate Database

Before you can start Designate, you need to create its database. Run the following commands to create a database with the required privileges:

sudo mysql
CREATE DATABASE designate;
GRANT ALL PRIVILEGES ON designate.* TO 'designate'@'localhost' IDENTIFIED BY '<DESIGNATE_DB_PASSWORD>';
FLUSH PRIVILEGES;
exit

Note: Replace the <DESIGNATE_DB_PASSWORD> placeholder with your own value.

Step 4: Starting Designate

Now that you've installed Designate and configured its settings, you can start the service by running the following commands:

sudo systemctl enable designate-central designate-api designate-mdns designate-sink
sudo systemctl start designate-central designate-api designate-mdns designate-sink
sudo systemctl status designate-central

To verify that the service is running, you should see output similar to the following:

● designate-central.service - OpenStack DNS As A Service - Central Agent
   Loaded: loaded (/lib/systemd/system/designate-central.service; enabled; vendor preset: enabled)
