External web URL not set in Prometheus

[Doug Szumski]

Kolla-Ansible deploys Prometheus behind HAProxy. As a user of Prometheus, I am sometimes redirected to the host running Prometheus rather than the HAProxy endpoint. For example, if I click a link in a Slack notification generated by Prometheus Alertmanager, I am redirected to the host running Prometheus Alertmanager which I may not have access to. The expected behaviour is that URLs returned from Prometheus services do not reference the node on which they are running, but always reference the appropriate HAProxy endpoint.

Prometheus provides support for this via the web.external-url flag. See here for more details:
