This is quite hilarious... $BASE_IMAGE is not defined in config.sh. So running this test would actually attempt to run something like docker -H=... run -e WEAVE_CIDR=10.2.1.4/24 grep ^1$ /sys/class/net/ethwe/carrier i.e. it would try to run the 'grep' image. So why does this not fail all the time? 1) 610_*.sh defines $BASE_IMAGE. 2) 620_*.sh builds a 'grep' image. If either of these tests are included in the same test run before 650_*.sh, then the latter will succeed. Throw in our fabulous CircleCI scheduler, which distributes tests according to their execution time, and you end up with sporadic failures. Fixes #938.
This directory contains integration tests for weave.
Requirements
You need two VMs with docker >=1.3.1 installed and listening on TCP port 2375 (see below). You also need to be able to ssh to these VMs, preferably without having to input anything.
The Vagrantfile in this directory constructs two such VMs. To meet
the aforementioned ssh requirement you may want to
cp ~/.vagrant.d/insecure_private_key .
Running tests
./setup.sh
uploads the weave images from where the Makefile puts them
(/var/tmp) to the two docker hosts, and copies the weave script
over.
Then you can use, e.g.,
./200_dns_test.sh
to run an individual test, or
./run_all.sh
to run everything named *_test.sh.
Using other VMs
By default the tests assume the Vagrant VMs are used.
To use other VMs, set the environment variable HOSTS to the
space-separated list of IP addresses of the docker hosts, and set the
environment variable SSH to a command that will log into
either (which may just be ssh).
Making docker available over TCP
To make docker listen to a TCP socket, you will usually need to either
run it manually with an option like -H tcp://0.0.0.0:2375; or, for
apt-get installed docker (Ubuntu and Debian), add the line
DOCKER_OPTS="--host unix:///var/run/docker.sock --host tcp://0.0.0.0:2375"
to the file /etc/default/docker, then restart docker.
