sudo87 · 2026-03-03T11:49:04Z

Description

This PR introduces initial implementation for a plugin based DNS framework in Apache CloudStack. It enables both admin and end-users to manage DNS zones and record with external authoritative dns providers.

First supported DNS provider: PowerDNS

Github issue: #9958
Cwiki: https://cwiki.apache.org/confluence/display/CLOUDSTACK/DNS+Framework+and+Plugins
Doc PR: apache/cloudstack-documentation#646

Terminology:

DNS Server: integration between CloudStack and DNS provider
DNS Zone: Domain scope
DNS Record: mapping entry with dns zones (e.g. mapping between names and ip)

API Changes

There are following APIs have been introduced to support DNS management from CloudStack and Instance auto registration:

[add/update/delete]DnsServer
[create/update/delete]DnsZone
[create/delete]DnsRecord
[associate/disassociate]DnsZoneToNetwork

UI changes

DNS Server subsection under Network
DNS Zone subsection under Network
DNS records management tab in the Dns Zone

Supported network for Auto Registration: Shared network

+
+    @Parameter(name = "externalserverid", type = CommandType.STRING, description = "External server id or hostname for the DNS server, e.g., 'localhost' for PowerDNS")
+    private String externalServerId;


is it applicable for PowerDNS only ?

I think we'd better avoid provider-specific parameters

+            description = "The ID of the DNS zone")
+    private Long id;


when delete a DNS zone, is it possible to keep the DNS records on the external provider ?

No, DNS records will no longer exist once DNS zone is deleted.

weizhouapache · 2026-04-28T09:58:03Z

+public enum DnsProviderType {
+    PowerDNS;
+//    Cloudflare
+}


there is an API to list all available DNS provider types:
ListDnsProvidersCmd, which calls listProviderNames

this enum may be not needed

this is used other places and is not used in listDnsProviderCmd

weizhouapache · 2026-04-28T11:04:56Z

+        }
+        HttpPost request = new HttpPost(buildUrl(baseUrl, port, "/servers/" + externalServerId + "/zones"));
+        request.setEntity(new StringEntity(json.toString(), StandardCharsets.UTF_8));
+        JsonNode response = execute(request, apiKey, 201);


if the DNS zone already exists in powerdns, what will happen ?

I wonder if DNS zone existence need to be checked before each DNS zone operation (create, update, list, delete), it will lead to 1 more API and cause longer response time. need to consider the trade-offs

Client throws DnsConflictException and it is shown in the API response as error:

DNS zone: %s already exists"
