[discussion] How to control for unusual situations

[anarcher]

Node from #331

Instance creation will create costs. If the problem is a configuration issue or other problem, the instance has been created for a while, but Infrakit will endlessly reproduce it because of flavor.Health decides the instance is "Unhealthy". It is a useless cost. Is there any way to prevent this? In AWS, Instance cost is charged per 1 hour. (Partial hours are billed as full hours.) (e.g. max-retry-num? Using circuit breaker?)

@anarcher Does this happen during creating new instances or only happens when performing a rolling update?
