“designate-central” service

Designate-Central acts as the central management service for DNS zones and records in OpenStack Designate. It coordinates with other Designate services and components to provide DNS functionality in an OpenStack environment.

Here are some key aspects of OpenStack Designate-Central:

1. DNS Zone Management: Designate-Central is responsible for managing DNS zones. It allows users to create, update, and delete DNS zones within the OpenStack environment. A DNS zone represents a portion of the DNS namespace and includes a collection of DNS records.
2. DNS Record Management: Designate-Central handles the management of DNS records within the designated DNS zones. It enables users to create, update, and delete various types of DNS records such as A, AAAA, CNAME, MX, TXT, and others. DNS records define the mapping between domain names and corresponding IP addresses or other data.
3. Service Coordination: Designate-Central acts as the central coordinator for other Designate services, including Designate-API, Designate-MDNS, and Designate-Sink. It communicates with these services to ensure seamless integration and coordination of DNS operations across the OpenStack environment.
4. Communication with DNS Servers: Designate-Central communicates with DNS servers to manage DNS zones and records. It interacts with the DNS servers using standard DNS protocols like DNS zone transfers (AXFR/IXFR) or using DNS server-specific APIs. This communication ensures that the DNS information is properly propagated and available to DNS resolvers and clients.
5. Integration with OpenStack Services: Designate-Central integrates with other OpenStack services, such as Keystone (identity service), Nova (compute service), and Neutron (network service). This integration enables Designate-Central to leverage the authentication, authorization, and networking capabilities of these services.
6. Scalability and High Availability: Designate-Central is designed to be scalable and highly available. It supports horizontal scaling by allowing multiple instances of Designate-Central to be deployed in a distributed manner. This ensures that the DNS management service can handle increased workloads and provides fault tolerance in case of failures.
7. API and CLI: Designate-Central provides a RESTful API and a command-line interface (CLI) for users to interact with and manage DNS zones and records. The API allows programmatic access to DNS management functionality, while the CLI provides a command-line interface for administrative tasks and automation.

Overall, OpenStack Designate-Central plays a crucial role in providing DNS management services within an OpenStack cloud environment. It ensures the availability, scalability, and coordination of DNS operations, making it easier to manage DNS zones and records in a cloud-based infrastructure.
