I can't capture cadvisor metrics with prometheus

Question

I can see the docker metrics at http://localhost:8080/metrics but prometheus can't connect

prometheus.yml

- job_name: cadvisor
    metrics_path: /metrics
    static_configs:
      - targets: ['cadvisor:8080']

error

Get "http://cadvisor:8080/metrics": context deadline exceeded

Check prometheus.yml with promtool check config prometheus.yml and throw SUCCESS: 0 rule files found
