Comment 3 for bug 1839824

Just to clarify the bug description - the problem is not that heat_user_domain exists, it is that the heat domain exists.

Relevant code in kolla, docker/heat/heat-api/extend_start.sh:

#!/bin/bash

# Bootstrap and exit if KOLLA_BOOTSTRAP variable is set. This catches all cases
# of the KOLLA_BOOTSTRAP variable being set, including empty.
if [[ "${!KOLLA_BOOTSTRAP[@]}" ]]; then
    heat-manage db_sync
    CURRENT_HEAT_DOMAIN_NAME=$(openstack domain list | grep heat | awk '{print $4}')

    if [[ "heat_user_domain" != "$CURRENT_HEAT_DOMAIN_NAME" ]]; then
        openstack domain create heat_user_domain
        openstack user create --domain heat_user_domain heat_domain_admin --password ${HEAT_DOMAIN_ADMIN_PASSWORD}
        openstack role add --domain heat_user_domain --user-domain heat_user_domain --user heat_domain_admin admin
    fi
    exit 0
fi

Alternatively we could make the above match more strict, to match on heat_user_domain exactly.
