Chaos Engineering/Fault Injection

[howardjohn]

What would you like to be added:

An API to inject faults into routes. Typically a fault may be a delay, an HTTP response, or others.

Why this is needed:

Fault injection / Chaos engineering is a somewhat common engineering practice to intentional introduce errors into the system to simulate disaster recovery and other reliability mechanisms.

Prior art:

• Istio

Slightly related to #2826

How do you see this being implemented, as a testing library that we provide to implementations or just an API?

[howardjohn]

No, just a HTTPRoute filter or policy. Like https://istio.io/latest/docs/reference/config/networking/virtual-service/#HTTPFaultInjection, for example. Then users or tooling can utilize that to build a holistic chaos engineering strategy

Ok, just wanted to be sure. The API specification for this sounds good, but the reason I asked about test libs is that I wouldn't be opposed to discussing having some standard "Gateway API Fault Injection" tooling. 🤔

In any case, I'm supportive of further discussing and working towards a proposal here.
