Comment 18 for bug 1773325

Problem seems to be in https://logs.rdoproject.org/openstack-periodic/git.openstack.org/openstack-infra/tripleo-ci/master/periodic-tripleo-ci-centos-7-multinode-1ctlr-featureset017-rocky/56e69c7/logs/undercloud/home/zuul/tempest-setup.sh

You are copying the tempest-deployer-input.conf to $TEMPEST_HOST_DATA that is /var/lib/tempestdata

# Copy all the required files in a temprory directory
export TEMPEST_HOST_DATA='/var/lib/tempestdata'

if [ ! -d $TEMPEST_HOST_DATA ]
then
    sudo mkdir -p $TEMPEST_HOST_DATA
fi

sudo cp $RCFILE \
        /home/zuul/skip_file \
            /home/zuul/whitelist_file.conf \
            /home/zuul/tempest-deployer-input.conf \
        /home/zuul/tempest_container.sh \
    $TEMPEST_HOST_DATA

And executing the tempestconf tool looking for /var/lib/tempest/tempest:

$TEMPESTCONF --out etc/tempest.conf \
    --deployer-input /var/lib/tempest/tempest/tempest-deployer-input.conf \
  --network-id $public_net_id \

Also the order is switched, you should set the variables, and then run tempestconf, here you're copying the deployer input file to $TEMPEST_HOST_DATA AFTER run tempestconf, which makes no sense for me
