CRC(CodeReady Containers) for Mac runs a DNS server for name resolution in the CRC VM on hyperkit. The DNS server is run as a container by Podman and starts dnsmasq. On the Mac, *.testing domain name resolution is directed to the CRC VM by "/etc/resolver".

The results of "podman inspect dnsmasq" in the CRC VM for Mac

$ export CRC_IP=$(crc ip)
$ ssh -i ~/.crc/machines/crc/id_rsa core@$CRC_IP
