Hi Onur,

I do not use netconf so I cannot comment.
But I do run Kea as a container. Here is my dockerfile for reference:

FROM alpine:latest

RUN apk add --no-cache tzdata && \
  cp /usr/share/zoneinfo/Asia/Tokyo /etc/localtime && \
  apk del tzdata
RUN apk add --no-cache kea-dhcp4 kea-admin mariadb-client kea-hook-mysql-cb
RUN mkdir -p /run/kea

ENTRYPOINT ["/usr/sbin/kea-dhcp4"]
CMD ["-c", "/etc/kea/kea-dhcp4.conf"]

You should adjust the timezone as appropriate. You can also remove
kea-admin, mariadb-client, and kea-hook-mysql-cb if you are not storing
your leases in an external database.

In your Kea config be careful of interfaces-config / interfaces. I needed
to alter mine from the default.

As for running the container, the easiest option is to run in
"network_mode: host" mode so that you receive the DHCP broadcasts.

It is more complicated if you want to give your container a dedicated
Dcoker network and only listen on 67/UDP. This will miss the DHCP
broadcasts, so you'll need an intermediate DCHP relay (such as a router) to
forward you such requests. You will also need to overwrite the DHCP server
IP that is returned so that clients can find your container host rather
than the internal Docker container when renewing.
