[Kea-users] kea docker

Michael,

I don't believe you can do a layer 2 broadcast out of the Docker network since it's routed internally. If you change the network mode on your Kea container to host mode, you might get some speed improvement (however small) and broadcast should work (it does in my testing).

Hi All,

I am new to Kea and Docker.

Looking to replace existing DHCP service + IPAM from Efficient IP to docker based DHCP server running Kea + phpIPAM.

See many guides on how to do this – This seemed to be good - https://github.com/xjasonlyu/docker-kea-dhcp4/tree/master. Env I have is secured and is not connect to the internet directly, and I have downloaded deb files manually and install it.

I assume that should do the trick and since I have new to docker also I need a test env to test this.
My desktop which is Ubuntu is running the docker and I assume the only way to test this is to create few docker containers and request IP from kea DHCP.  I know this is going out of scope, but can container setup to use DHCP and will kea DHCP server broadcast outside the docker network?

Kind Regards,

Michael
