We using openshift routes to interact with neutron APIs and default timeout for it is 30s, if request takes more than 30 second we see below error:-

Error while executing command: HttpException: 504, 504 Gateway Time-out: The server didn't respond in time.

We need to provide tuning option for this with some good default configured.

One option i found to handle this is to add annotations: haproxy.router.openshift.io/timeout: <timeout>s to the routes.

via commands:-

oc annotate route neutron-public --overwrite haproxy.router.openshift.io/timeout=120s
