• CoreDNS on Kubernetes: Allow DNS zone transfer

    3 min read

    kubernetes CoreDNS

    Kubernetes, by default, registers all the Pods and services using the cluster.local DNS zone. At some point we might want to be able to take a look at this zone. Zone transfers are going to be restricted by default:

    dnstools# dig axfr cluster.local
    ; <<>> DiG 9.11.3 <<>> axfr cluster.local
    ;; global options: +cmd
    ; Transfer failed.

    But if we are using CoreDNS, we can configure it to temporally allow zone transfers to be able to take a look at it

Treat your kubernetes clusters like cattle, not pets
