Opentelemetry collector contrib for azure monitor in aks as standalone not working

I am trying to have a standalone deployment of otel collector contrib for exporting logs to azure monitor by deploying in aks. I try to push the logs but none of the logs are reaching the collector. Any working yaml configuration will be helpful

I try to push the logs but none of the logs are reaching the collector.

        logs:

• Below is the Deployment YAML that references the ConfigMap. This configuration mounts the config.yaml from the ConfigMap and check that the Collector is started with the appropriate configuration.

          ports:
            - containerPort: 4317 # OTLP gRPC
            - containerPort: 4318 # OTLP HTTP
            - containerPort: 55679 # zPages
            - containerPort: 13133 # health check
          volumeMounts:
            - mountPath: /etc/otelcol-contrib/config.yaml
              name: config
              subPath: config.yaml
              readOnly: true
      volumes:
        - name: config
          configMap:
            name: otel-collector-config

After deployment, verify that the OpenTelemetry Collector is running and exporting logs.
