# Spins up a Centos8 container and runs the wait_for_connection test inside of it
# Doing it this way because the shutdown command causes issues in our tests
#   since things are ran on localhost; Azure DevOps loses connection and fails
# TODO: do we want to install docker a different way to be able to do this for other tests too
---
# this should only run on our Mac hosts
