Mediamtx webrtc stream is not accessible while running inside k8s cluster in minikube

I running a mediatmx server on minikube kubernetes cluster. I am passing a rtsp stream as input to the mediamtx server through mediamtx config file as path entry.

Now I am trying to access the corresponding Webrtc stream locally from my browser, by using kubectl port forward to forward mediamtx service to localhost. But I am not able to access the webrtc stream from the browser

Steps to recreate the Issue

1. Create minikube cluster.
2. Deploy mediamtx Deployment, Service and Config Map
   The Config map include custom mediamtx.yml config

Your custom MediaMTX configuration goes here

webrtcICEServers2:

– url: stun:stun2.1.google.com:19302

paths:

example:

mycamera:
source: rtsp://admin:[email protected]:554/unicaststream/1

all_others:

4. The Config map includes custom mediamtx configuration. I have added a default rtsp stream path entry to it, And trying to access the corresponding webrtc streams.

5. Apply all resources, wait for medamtx pod to start. Expose mediamtx service using kubectl port-forward

Now the webrtc stream should be accessible at http://localhost:8889/mycamera, But I am not able to access it
