During upgrade testing, move Keystone containers behind an HAProxy
load balancer and run a benchmarking tool to make continuous requests
against the keystone API, providing summary output at the end of the
play. This should help ensure the upgrade process between releases
remains without downtime.
To avoid service interruptions because of files being replaced during
installations:
- set the 'keystone_venv_tag' var so that it changes between releases
- perform the 'Create WSGI symlinks' task only after the files being
linked to exist
Benchmarking scripts were provided by:
