This commit does several things to allow functional tests to run, using a
DevStack configuration, but without stacking.
First, the gate_hook.sh is modified to specified environment variables
needed for processing, and will call configure_vpn_for_func_testing.sh.
The new configure_for_vpn_func_testing.sh script will first call the Neutron
configure_for_func_testing.sh script (as modified in [1]) to setup DevStack.
The script then installs the IPSec package, based on the functional job, and
will create the vpn_agent.ini file, in case it is needed for tests.
Minor changes are made to the post-test_hook.sh to indicate the location for
the Neutron and VPN repos.
Lastly, tox.ini is modified to place the rootwrap related files into the
virtual environment, copy in the VPN rootwrap filter, set up the rootwrap
commands, and copy the (customized) rootwrap.conf to /etc/neutron.
This last step is needed, because the neutron-vpn-netns-wrapper script that
is (currently) used for StrongSwan, uses /etc/neutron/rootwrap.conf and
doesn't allow overriding. This copying is a simple approach that will work
when multiple functional jobs are running, as the same config is used.
As a future follow-up commit, we could look into modifying the VPN device
drivers to pass the full path to the rootwrap.conf as a argument to the
neutron-vpn-netns-wrapper script (--rootwrap_config). The setting could
be added to the vpnagent.ini config file, available via config, to allow
this to be customized to something other than /etc/neutron (for production
use), and the functional tests could override it to point to the right
virtual environment.
To configure the environment for local run of the functional test, one
can do:
tools/configure_for_vpn_func_testing.sh <devstack-repo> [-i]
where:
devstack-repo... Path to devstack repo (/opt/stack/new/devstack
when run by gate)
-i.............. Indicates to install Neutron package dependencies
For StrongSwan, prefix the command with VENV=dsvm-functional-sswan
