This project provides a standalone OpenStack Designate service. All dependent services such as the OpenStack Keystone service are provided as well. OSISM is used as the lifecycle management solution for this.

The purpose of this project is to be able to use Gardener on OpenStack-based CSPs that do not yet have a Designate in use without having to rely on an external DNS service.

It is intended as an interim solution until the respective CSPs provide Designate themselves. It's not meant to be a long-term solution.

The project is provided "AS IS", without warranty of any kind.

The first step is to create a new floating IP address on which the Designat endpoint and the name server are made available.

make openstack ENVIRONMENT=citycloud
(openstack) floating ip create -f json ext-net
{
  "created_at": "2021-06-11T19:38:12Z",
  "description": "",
  "dns_domain": null,
  "dns_name": null,
  "fixed_ip_address": null,
  "floating_ip_address": "91.123.203.120",
  "floating_network_id": "2aec7a99-3783-4e2a-bd2b-bbe4fef97d1c",
  "id": "43fa2b45-2365-478e-bf7c-607078aa07e3",
  "name": "91.123.203.120",
  "port_details": null,
  "port_id": null,
  "project_id": "xxx",
  "qos_policy_id": null,
  "revision_number": 0,
  "router_id": null,
  "status": "DOWN",
  "subnet_id": null,
  "tags": [],
  "updated_at": "2021-06-11T19:38:12Z"
}

Next, A and NS records for this IP address are created on an existing name server. In this case, later citycloud.23technologies.xyz is to be managed by Designate. Via citycloud.designate-in-a-box.23technologies.xyz, the Designate API endpoint will be available.

A - citycloud.designate-in-a-box.23technologies.xyz - 91.123.203.120 (TTL = 1800)
NS - citycloud.23technologies.xyz - 91.123.203.120 (TTL = 1800)

Before creating the environment, make sure that the A-record resolves correctly. Otherwise, the creation of the certificate via Letencrypt will not work.

The previously created floating IP address is now made available.

make attach ENVIRONMENT=citycloud PARAMS=43fa2b45-2365-478e-bf7c-607078aa07e3

If the environment is removed or rebuilt, the floating IP address should be detached first. So it can be reused later.

make detach ENVIRONMENT=citycloud

To create a Designate service that manages the domain citycloud.23technologies.xyz with the endpoint at citycloud.designate-in-a-box.23technologies.xyz proceed as follows:

cd terraform
make create \
     ENVIRONMENT=citycloud \
     DOMAIN=citycloud.23technologies.xyz \
     ENDPOINT=citycloud.designate-in-a-box.23technologies.xyz
