# This is a helper script to make it easier for me to test all ick
# compontents together.
#
# This script optionally installs (based on first arg: yes or no) ick
# on a cluster, and then sets up a couple of test projects, and builds
# those.
#
# See the run-cluster.sh file for how the cluster is set up.
#
# The ci-vars.yaml file has the variables for setting up the test
# instance.
#
# See ickdev.yaml for the ick projects that are set up: ick_streatch
# and ick2. If you change the project names, you need to edit this
# file.
#
# This script assume you have icktool installed and configured, and
# that the ick2-ansible repository is checked out at a given location
# (see below). Also the ick rules are checked out (liw-ci repo). Also,
# the cluster hostnames are listed in hosts.ickdev. All of the various
# values work for me. If you'd like to make this more general, that'd
# be fantastic: please submit patches.
