- job_name: 'kubernetes-nodes' - not working

[martinmalek]

In
https://github.com/giantswarm/prometheus/blob/master/manifests-all.yaml#L2438

you refer to
https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml#L37

(which btw has moved to)
https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml#L59

and should look like

- job_name: 'kubernetes-nodes'

  # Default to scraping over https. If required, just disable this or change to
  # `http`.
  scheme: https

  # This TLS & bearer token file config is used to connect to the actual scrape
  # endpoints for cluster components. This is separate to discovery auth
  # configuration because discovery & scraping are two separate concerns in
  # Prometheus. The discovery auth config is automatic if Prometheus runs inside
  # the cluster. Otherwise, more config options have to be provided within the
  # <kubernetes_sd_config>.
  tls_config:
    ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token

  kubernetes_sd_configs:
  - role: node

  relabel_configs:
  - action: labelmap
    regex: __meta_kubernetes_node_label_(.+)
  - target_label: __address__
    replacement: kubernetes.default.svc:443
  - source_labels: [__meta_kubernetes_node_name]
    regex: (.+)
    target_label: __metrics_path__
    replacement: /api/v1/nodes/${1}/proxy/metrics

instead of as you suggest

- job_name: 'kubernetes-nodes'
  tls_config:
    ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  kubernetes_sd_configs:
    - role: node
  relabel_configs:
    - source_labels: [__address__]
      regex: '(.*):10250'
      replacement: '${1}:10255'
      target_label: __address__

At least for me your example didn't work.
