Powerdns recursor api tips Error

[zhaohong-ponyai]

Background:
Use docker image powerdns/pdns-recursor-45:latest, Then set PDNS_RECURSOR_API_KEY variable to enable the Api
Phenomenon:
Forward-zone creation via restful api calls
Request:
curl -H "Content-type: application/json" -H 'X-API-Key: abcdefghijklmn' -X POST -d '{"name":"test-query.my-domain.com. ","type":"Zone","kind":"Forwarded","servers":["8.8.8.8"],"recursion_desired":false}' http://127.0.0.1:8081/api/v1/servers/localhost/zones

In my recursor docker service, the api configuration file is as follows:

include-dir=/etc/powerdns/pdns-recursor
api-config-dir=/etc/powerdns/pdns-recursor

Then when docker runs, the container path/etc/powerdns/pdns-recursor is also mounted to the host, and then after calling api, i can also see that this directory generates a new forward-zone file, but api will give an error message {"error": "Could not find domain 'test-query.my-domain.com}, it seems that the recursor service can not load this api-config-dir file. I tried configuring forward-zones= test-query.my-domain-two.com = 8.8.8.8:53 in recursor.conf to load this configuration successfully, but the api-conf-dir file was not loaded successfully, but it was created by api call.

How do I troubleshoot the problem? I have tried to deploy recursor directly in the virtual machine, and then use the same api call to create a forward-zone is OK, but after changing to docker, it won't work. Please help me take a look? Thanks

Recursot 4.5.x is ancient and not supported anymore. As a first step, try to run a supported version. See https://docs.powerdns.com/recursor/appendices/EOL.html
