# Testing with net-tools and Docker

* Create Docker image

	cd docker/
	docker build -t net-tools .

* Setup network interfaces, IP addresses and routes

	./net-setup.sh --config docker.conf

* Run Docker image

  Set the docker internal network name to the value $DOCKER_USER_INTERFACE
  in docker.config above, default is 'net-tools0'. The bridge network that
  docker creates will be printed on standard out, it's bridge interface
  name will be br-XXXXXXXXXXXX. Check that the IPv4 and IPv6 addresses
  given on the docker command line match the subnets in 'docker.conf'.

  Interactively:

	docker run --hostname=zephyr --name=net-tools \
	       --ip=192.0.2.2 --ip6=2001:db8::2 \
	       --rm -it --network=net-tools0 net-tools sh

        exit with Ctrl-p ctrl-q to execute tests from the command line

  Non-interactively

	docker run --hostname=zephyr --name=net-tools \
	       --ip=192.0.2.2 --ip6=2001:db8::2 \
	       --rm -dt --network=net-tools0 net-tools sh

* Run Qemu / native-posix image

	rm -rf build && mkdir build

	cmake -GNinja -DBOARD=native_posix -B build
	   or
	cmake -GNinja -DBOARD=qemu_x86 -DOVERLAY_CONFIG=overlay-e1000.conf \
	   -B build

	ninja -C build run

* Execute tests like echo-client

	docker container exec net-tools /net-tools/echo-client 2001:db8::1
	docker container exec net-tools /net-tools/echo-client -t 2001:db8::1
	docker container exec net-tools /net-tools/echo-client 192.0.2.1
	docker container exec net-tools /net-tools/echo-client -t 192.0.2.1

* Remove the 'net-tools0' docker network:

	docker network rm net-tools0
