## Using ./run-test-distros.sh
You can use `./run-test-distros.sh` to run a set of tests via DIND,
and excerpt from this script, to get an idea:
~~~
# The SPEC file(s) must have two arrays as e.g.
# DISTROS=(debian centos)
# EXTRAS=(
# 'kube_network_plugin=calico'
# 'kube_network_plugin=flannel'
# 'kube_network_plugin=weave'
# )
# that will be tested in a "combinatory" way (e.g. from above there'll be
# be 6 test runs), creating a sequenced <spec_filename>-nn.out with each output.
#
# Each $EXTRAS element will be whitespace split, and passed as --extra-vars
# to main kubespray ansible-playbook run.
~~~
See e.g. `test-some_distros-most_CNIs.env` and
`test-some_distros-kube_router_combo.env` in particular for a richer
set of CNI specific `--extra-vars` combo.
