It is related to the certification. Bug report received by email:

I tried this solution and proxt does not still get set in env and discover_tempest_config still tries to get the glance image without using proxy. I can even see the deployer Inputs set in the CRD

 tempestconfRun:
   append: ""
   collectTiming: false
   convertToRaw: false
   create: true
   createAccountsFile: ""
   debug: true
   deployerInput: |
     [service-clients]
     proxy_url=http://proxy.esl.cisco.com:80/
   flavorMinDisk: 0
   flavorMinMem: 0

Even if this works, I will still need to set no_proxy  which seems to be missing.

I have tried every trick to set proxy (and no_proxy) in Tempest CR. Even tried to put them directly in /usr/share/redhat-certification-rhoso/rhoso-cert-neutron.yaml  but the pod does not pick it up. This is an overlook which seems to be common in many Red Hat solutions.

Please provide a tested workflow that works behind a proxy (an also add this to documentation).
