Test Suite - Docker

Libreswan testing suite docker adventures.

Everything below runs as root on Fedora 20

#swantest depend on python 3.3 or later

yum install python3-setproctitle python3-pexpect

# install docker 1.3
yum -y remove docker 
yum -y install docker-io bridge-utils
yum -y update docker-io
systemctl start docker
systemctl enable docker

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 20 + about 200 packages 
# my experience on swantest real 19m31.907s, on parallels vm from Toronto real 7m1.228s

# make sure the host has netkey stack loaded 
ipsec _stackmanager start --netkey
ipsec version |grep klips && echo you need netkey

Docker related diagnostics commands

# show running docker containers
docker ps -a 

# check if you have a proper docker installation?
docker images

# stop ALL containers 
docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

# if your tests it create a bunch of bridge devices too. Not all of them are cleaned up.

brctl show

Check if you got correct image

cd /home/build/libreswan/testing/docker

docker build -t swanbase .

Prerequisites

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.

=== Attempt to run as user build

1. run docker as user build

sudo groupadd docker
usermod -a -G docker build

Notes

1. currently support install rpms (on both initiator and responder). May be separate options so can have different version on both sides.
2. Add strongswan package or just install runtime? or keep different image?
3. take eth0 from docker bridge? currently docker has 3 ethernets eth0 (unused, bridged to docker) eth1 and eth2. this cause mismatch with kvm tests. they have eth0 and eth1
4. delete brige interfaces after the test is done
5. option to clean up all bridges?
6. make install for docker. support "ipsec start" in Docker
7. run as user build
