I am looking to launch a new slave on the run from a Jenkins job using an OpenStack template. I intend to use the OPENSTACK_PUBLIC_IP for my cloud template in the build step to get an SSH connection to it. However, if I try "echo ${OPENSTACK_PUBLIC_IP}" in Execute Shell build step, there is no IP value printed in the build logs.
