Created attachment 1264738 [details] customized keystone role and environment files Description of problem: I'm trying to deploy in a virtual environment with OSP10. I am using the default templates with a customized roles_data.yaml (I have a separated keystone role there and a serviceapi role) and network isolation. Deployment fails with a very long error message (see attached text file). It says "Error parsing template" but it doesn't say exactly where and I am stuck with it. The deployment command that was used is: openstack overcloud deploy --templates -r roles_data.yaml --neutron-network-type vxlan --neutron-tunnel-types vxlan,gre --ntp-server clock.redhat.com -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml -e network-environment.yaml See also attached tgz file with the roles data and network environment files. Version-Release number of selected component (if applicable): openstack-heat-engine-7.0.2-1.el7ost.noarch openstack-heat-templates-0-0.11.1e6015dgit.el7ost.noarch python-heatclient-1.5.0-1.el7ost.noarch How reproducible: Steps to Reproduce: 1. Use the attached tgz which contains the network environment and custom roles_data.yaml. 2. Run the deployment command from above. Actual results: Error parsing template Expected results: The error is not specific enough. I can't guess where the problem is and I'm stuck the whole day on it.

It looks like when a validation error occurs in a nested stack we're not including information about which nested stack it's in. Other than that, the message is pretty clear: ERROR: Failed to validate: Failed to validate: resources[0]: Error parsing template: while parsing a block collection in "<unicode string>", line 83, column 13: - ^ expected <block end>, but found '?' in "<unicode string>", line 102, column 13: members: ^ It's at line 102, column 13 of some template, which is resource "0" in its parent stack (so it's likely a member of a ResourceGroup). We don't know which template, but we do know that line says "members:", and also what line 83 says. Creating the overcloud normally works, so it's likely that one of the customised templates is the culprit. In this case it's serviceapi.yaml - there should be an extra two spaces at the beginning of line 102.
Verified in openstack-heat-engine-9.0.1-0.20171023060845.be1e2e9.el7ost.noarch The error message now contains the file name where the parse error occurred: Error parsing template http://192.168.24.1:8080/v1/AUTH_c288d80d9b4646cb872d67109626440c/overcloud/user-files/home/stack/nic-configs/compute.yaml while parsing a block collection\n in "<unicode string>", line 71, column 13:
