Register mDNS records to AWS Route53 In local network, I can use mDNS names like DESKTOP-RHM4944.local, but I cannot use mDNS name over OpenVPN. I uses openvpn to access office network, and I want to be able to find out client IP of certain PC. and the PC uses DHCP to obtain dynamic IP.
I have AWS environment, so I can use Route32 to resolve local hostname.

But, some times you may experience some of container cannot access AWS Resources.
In that case, the container might be being assigned docker network that is overwrapping with AWS VPC network.
To prevent this to happen, you can create docker network that is same as AWS VPC to not to be used as container network.
