How to Fault Injection for redis

Networking
1

Redis is called in my app。

I need to implement fault injection for redis. What should I do?

For example, after my fault is injected, call redis to return 500.

If I recall correctly, redis does not use HTTP; it’s a custom protocol. I don’t believe Istio/Envoy have support for fault injection in the redis protocol, that’s only for HTTP.

Istio does not provide TCP fault injection, but I use traffic forwarding instead of fault injection.
Forward to unknown service…
