Comment 0 for bug 1638908

We are getting frequent issues in RDO-CI when using tripleo-quickstart with minimal profile, API calls to services in undercloud fail with messages ('Connection aborted.', BadStatusLine("''",)) when deploying the overcloud.

Examples:

https://ci.centos.org/artifacts/rdo/jenkins-tripleo-quickstart-promote-newton-delorean-minimal-72/undercloud/home/stack/overcloud_deploy.log.gz

Unable to establish connection to https://192.0.2.2:13004/v1/71e3a94ea39841d8902095ea052c1982/stacks/overcloud/64b3278e-52b1-46b7-b7c3-bc32f361ab77: ('Connection aborted.', BadStatusLine("''",))

https://ci.centos.org/artifacts/rdo/jenkins-tripleo-quickstart-promote-newton-delorean-minimal-91/undercloud/home/stack/overcloud_deploy.log.gz

Unable to establish connection to https://192.168.24.2:13004/v1/f0aba169cfbd4985a1d42d55e3d92c88/stacks/overcloud/202f02eb-bcf3-4149-a5d6-6fb167877d28: ('Connection aborted.', BadStatusLine("''",))

https://ci.centos.org/artifacts/rdo/jenkins-tripleo-quickstart-promote-newton-delorean-minimal-92/undercloud/home/stack/overcloud_deploy.log.gz

At that point "openstack overcloud deploy" command exits while heat is still working to create the stack (as seen in https://ci.centos.org/artifacts/rdo/jenkins-tripleo-quickstart-promote-newton-delorean-minimal-72/undercloud/var/log/heat/heat-engine.log.gz and job fails in overcloud-deploy-post.sh with error:

/home/stack/overcloud-deploy-post.sh: line 38: /home/stack/overcloudrc: No such file or directory

We don't find similar errors in minimal_pacemaker jobs which doesn't includes haproxy running in undercloud so i wonder if this could be related to it.
