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

I am facing an issue while trying to access a MediaMTX WebRTC stream that is deployed inside a Minikube Kubernetes cluster. The deployment seems to be set up correctly, but I cannot access the WebRTC stream, and I am getting a timeout error when trying to establish a connection.

Steps to Replicate the Issue:

1. Create a Minikube Cluster: Set up a Minikube cluster using the default configuration.

2. Deploy MediaMTX: Deploy the following resources: a Deployment, a Service, and a ConfigMap.

The Config map include custom mediamtx.yml config

Mediamtx Deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mediamtx
  labels:
    app: mediamtx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mediamtx
  template:
    metadata:
      labels:
        app: mediamtx
    spec:
      containers:
      - name: mediamtx
        image: bluenviron/mediamtx
        args: ["/mediamtx.yml"] # Explicitly specify the config file location
        volumeMounts:
        - name: config
          mountPath: /mediamtx.yml
          subPath: mediamtx.yml
        ports:
        - containerPort: 8554
        - containerPort: 1935
        - containerPort: 8888
        - containerPort: 8889
        - containerPort: 8890
        - containerPort: 8189
        env:
        - name: MTX_PROTOCOLS
          value: "tcp"
        - name: MTX_WEBRTCADDITIONALHOSTS
          value: "172.19.0.1" # Adjust as needed
      volumes:
      - name: config
        configMap:
          name: mediamtx-config
          defaultMode: 0644  # Ensure the file is readable

Mediamtx Service

apiVersion: v1
kind: Service
metadata:
  name: mediamtx
spec:
  type: ClusterIP
  ports:
    - name: rtsp
      port: 8554
      targetPort: 8554
      protocol: TCP
    - name: rtmp
      port: 1935
      targetPort: 1935
      protocol: TCP
    - name: web
      port: 8888
      targetPort: 8888
      protocol: TCP
    - name: web-rtc
      port: 8889
      targetPort: 8889
      protocol: TCP
    - name: rtsp-udp
      port: 8890
      targetPort: 8890
      protocol: UDP
    - name: udp-extra
      port: 8189
      targetPort: 8189
      protocol: UDP
  selector:
    app: mediamtx

mediamtx config map

apiVersion: v1
kind: ConfigMap
metadata:
  name: mediamtx-config
data:
  mediamtx.yml: |
    paths:
      mycamera:
        source: rtsp://admin:[email protected]:554/unicaststream/1

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

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

Mediamtx server logs after trying to access webrtc stream

I am trying to access the stream at localhost:8889/mycamera after running kubectl port-forward svc/mediamtx 8889:8889

I also tried adding stun/turn server in mediamtx config

# webrtcICEServers2:
# - url: stun:stun2.1.google.com:19302

Also tried adding webrtc address as broadcast in mediamtx config

# rtspAddress: 0.0.0.0:8554

Still I am unable to acesss I get following errrors in browser console
