Test Suite - Docker
Libreswan testing suite docker adventures.
Everything below runs as root on Fedora 26
Setting up the host
The swantest need Python 3.3 or later. It is necessary for subprocess to deal with 100s of threads/processes. Also pexpect is works better in 3.3.
#swantest depend on python 3.3 or later dnf install python3-setproctitle python3-pexpect # install docker dnf -y install docker systemctl start docker.service systemctl enable docker.service wget -O /usr/local/bin/pipework https://github.com/jpetazzo/pipework/raw/master/pipework chmod a+x /usr/local/bin/pipework cd /home/build/ # clone an up to date libreswan tree from somewhere to /home/build/ cd /home/build/libreswan/testing/docker/ # check authorized_keys file edit or add your your keys in there docker build -t swanbase . # coffee break. It will download Fedora 22 + about 200 packages. It may take 15 minutes or more # my experience on blueswan real 15m18.893s user 0m0.123 sys 0m0.057s # make sure the host has netkey stack loaded ipsec _stackmanager start --netkey ipsec version |grep klips && echo you need netkey cd /home/build/libreswan/ make programs cd /home/build/libreswan/testing/pluto/ikev2-37-docker-rw ../../utils/swantest --docker iptables -F ; the iptable rules on host and docker may interfere with IKE or ESP

Manually update the swanbase (base docker image)
Start the docker image by hand. Note this instance will have access to network, via bridge docker0
docker run -h swan --privileged --name swan -v /home/build/libreswan:/home/build/libreswan -v /sys/fs/cgroup:/sys/fs/cgroup:ro -d swanbase /usr/sbin/init docker exec -ti swan /bin/bash dnf -y update # now commit the images as tag swanbase. docker ps ; to see image id docker commit <docker id> swanbase # to stop this instance docker stop --time=1 swan docker rm swan === Notes === # currently support install rpms (on both initiator and responder). May be separate options so can have different version on both sides. # Add strongswan package or just install runtime? or keep different image? # delete brige interfaces after the test is done # option to clean up all bridges? # make install for docker. support "ipsec start" in Docker
