Envoy Support and Configuration for ServiceDisruptor with Istio #397

Closed denisqsound closed 4 months ago

denisqsound commented 4 months ago

Hello xk6-disruptor team,

I am exploring the use of ServiceDisruptor in a Kubernetes cluster and have a question regarding its compatibility and configuration with Envoy (istio). Specifically, I would like to know if there is support for scenarios where the network configuration is managed through Istio (istio-iptables), and the pods behind the service do not have a defined ports section in their configuration.

Here's what I'm trying to achieve: I want to set up ServiceDisruptor for a service that is backed by pods. These pods have their network traffic managed via Istio, and as such, they don't include the typical ports configuration like this:

  ports:
    - name: http
      containerPort: 3333
      protocol: TCP

Could you please provide guidance or documentation on how to configure ServiceDisruptor in such a setup? Any examples or best practices would be greatly appreciated.

While attempting to configure this, I am facing the following error:

GoError: error injecting fault: unable to get command for pod "frontend-bb577bb46-4qkjv": pod "frontend-bb577bb46-4qkjv" does not export port "3333"

Thank you for your assistance.

@denisqsound Unfortunately we don't currently support this configuration.
