k8s deployment

i'm getting error after deployment - Prometheus couldn't use the end point...

  /etc/prometheus/config_out $ wget http://avalanche-svc.avalanche.svc.cluster.local:9001
  Connecting to avalanche-svc.avalanche.svc.cluster.local:9001 (10.244.0.97:9001)
  wget: server returned error: HTTP/1.1 404 Not Found

However, I found the pod logs - looks like it's generating metrics.

this is my scrap config in Promethues.

    - job_name: avalanche
      scrape_interval: 1m
      scrape_timeout: 10s
      metrics_path: /metrics
      scheme: http
      static_configs:
        - targets:
          - http://avalanche-svc.avalanche.svc.cluster.local:9001

This is my deployment file.

same problem here, maybe because the server can only accept requests from localhost?
