NGINX on Load Balancer should restart when it crashes #5382

Open tpendragon opened 5 days ago

tpendragon commented 5 days ago

We recently had an incident where nginx segfaulted after a reload and never came back up. It should come back up when it crashes.

Acceptance Criteria

[ ] When nginx crashes it should automatically restart.

Related to #4893.

Looks like our HA solution, keepalived, expects initd/service instead of systemd so we need to be careful about how we mix the configs. It's probably time to open a ticket with nginx for a bulletproof, integrated solution.
