Unable to use kubernetes_endpoints role :: Unknown Kubernetes SD role \"endpoints\"

[Junaid Subhani]

I am using Prometheus as a container inside my K8S cluster. My current working configMap is ::

apiVersion: v1
kind: ConfigMap
metadata:
  name: prometheus
data:
  prometheus.yml: |-


    # This file comes from the kubernetes configmap
    rule_files:
    - '/etc/prometheus-alert-rules/alert.rules'


    global:
      scrape_interval: 5s


    scrape_configs:
    - job_name: 'kubernetes_apiserver'
      tls_config:
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - api_servers:
        - http://172.29.219.65:8080
        role: apiserver
      relabel_configs:
      - source_labels: [__meta_kubernetes_role]
        action: keep
        regex: (?:apiserver)


     ###################### Kubernetes Pods ##########################
    - job_name: 'haproxy'
      static_configs:
        - targets:
          - 172.29.219.110:9101


    - job_name: 'docker_containers'
      metrics_path: '/metrics'
      tls_config:
        insecure_skip_verify: true
      static_configs:
         - targets:
           - 172.29.219.103:4194
           - 172.29.219.104:4194
           - 172.29.219.105:4194


    - job_name: 'kubernetes_pods'
      tls_config:
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - api_servers:
        - http://172.29.219.65:8080
        role: pod
      relabel_configs:
        - source_labels: [__meta_kubernetes_pod_name]
          action: replace
          target_label: pod_name
        - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
          action: replace
          target_label: __metrics_path__
          regex: (.+)

Now I want to monitor the End points so Ive added the below config to my configMap ::

    - job_name: 'kubernetes_endpoints'
      tls_config:
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - api_servers:
        - http://172.29.219.65:8080
        role: endpoints
      relabel_configs:
      - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_scrape]
        action: keep
        regex: true

But when I boot up my deployment, the Pod ERRORs out with the following ::

time="2017-05-26T13:56:46Z" level=info msg="Loading configuration file /etc/prometheus/prometheus.yml" source="main.go:221" 

time="2017-05-26T13:56:46Z" level=error msg="Error loading config: couldn't load configuration (-config.file=/etc/prometheus/prometheus.yml): Unknown Kubernetes SD role \"endpoints\"" source="main.go:126"

Why does such an error occur ? It does not complain about role: pod OR role: apiserver .

Try a newer version of Prometheus, the config format has changed since the version you're using.
