Kubelet Connection Refused

[pdrcastro]

Hi camilb,

Before i describe my problem, i want to thank you for your amazing work.

My scenario is:
Kubernetes AWS EKS with autoscaling V1.11.

Everything is ok except the kubelet is try to connect on port 10255 but in server kubelet is listen in port 10250.

How can i fix this ?

I try to change my service monitor for:
**```
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
labels:
k8s-app: kubelet
name: kubelet
namespace: monitoring
spec:
endpoints:

• bearerTokenFile: /var/run/secrets/kubernetes.io/serviceaccount/token
  honorLabels: true
  interval: 30s
  port: https-metrics
  scheme: https
  tlsConfig:
  insecureSkipVerify: true
• bearerTokenFile: /var/run/secrets/kubernetes.io/serviceaccount/token
  honorLabels: true
  interval: 30s
  metricRelabelings:
  • action: drop
    regex: container_([a-z_]+);
    sourceLabels:
    • name
    • image
  • action: drop
    regex: container_(network_tcp_usage_total|network_udp_usage_total|tasks_state|cpu_load_average_10s)
    sourceLabels:
    • name
      path: /metrics/cadvisor
      port: https-metrics
      scheme: https
      tlsConfig:
      insecureSkipVerify: true
      jobLabel: k8s-app
      namespaceSelector:
      matchNames:
  • kube-system
    selector:
    matchLabels:
    k8s-app: kubelet

And for this without success.

**apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: kubelet
  labels:
    k8s-app: kubelet
spec:
  jobLabel: k8s-app
  endpoints:
  - path: /metrics/cadvisor
    port: http-metrics
    interval: 30s
    honorLabels: true
  selector:
    matchLabels:
      k8s-app: kubelet
  targetLabels:
    - app
    - prometheus
    - beta.kubernetes.io/instance-type
    - kops.k8s.io/instancegroup
    - failure-domain.beta.kubernetes.io/zone
    - name
    - address
  namespaceSelector:
    matchNames:
    - kube-system**

Thanks.
