How to Inject Faults into Common HTTP(S) Clients and Services

HTTP(S) is one of the most popular application protocols. Many well-known applications, such as Kubernetes and TiDB, heavily rely on the HTTP(s) protocol. However, HTTP connections might fail due to various faults, such as network aborts, long delays, or even man-in-the-middle attacks, causing services unavailable to users. In such cases, simulating HTTP faults with a chaos engineering tool can be extremely beneficial to ensure the robustness and resilience of the application, particularly distributed ones. In this talk, Chenxi Li will show how to implement the HTTPChaos, a chaos engineering mechanism that injects faults into common HTTP applications without any configurations. The theory and rust implementation of a transparent proxy, the hijack solution of HTTPS services on Kubernetes, and the plugins used to inject the message body as custom requirements will also be covered.
