HEAT template file fails in validation in OSP7 & OSP 8

Solution Verified - Updated -


  • Starting with Red Hat OpenStack 7, during the resource validation heat complained network or network_id shall be included in properties.
    However, the same script and template has worked fine in JUNO.

The error appears is the following:

ERROR: Failed to validate: Failed to validate: Failed to validate: At least one of the following properties must be specified: network, network_id
  • Same issue is reported in RHEL OSP 8 as well.


  • Red Hat OpenStack 7.0
  • openstack-heat-common <= 2015.1.2-4.el7ost
  • Red Hat OpenStack 8.0
  • openstack-heat-common-5.0.1-5.el7ost.noarch
