kubernetes + traefik + prometheus + grafana

• kubernetes安装步骤参看前文

• traefik 安装步骤略。

• prometheus 和grafana安装

  1. 安装helm
  2. helm安装prometheus
     • http://www.jianshu.com/p/58df553d5697
  3. helm安装grafana

• 访问grafana配置数据源类型为Prometheus,URL为http://prometheus-prometheus-server

• 导入dashboard:

  • kubernetes cluster monitor
    • 需要在prometheus中添加以下配置

       scrape_configs:
         - job_name: kubernetes-nodes-cadvisor
           scrape_interval: 10s
           scrape_timeout: 10s
           scheme: https  # remove if you want to scrape metrics on insecure port
           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_(.+)
             # Only for Kubernetes ^1.7.3.
             # See: https://github.com/prometheus/prometheus/issues/2916
             - target_label: __address__
               replacement: kubernetes.default.svc:443
             - source_labels: [__meta_kubernetes_node_name]
               regex: (.+)
               target_label: __metrics_path__
               replacement: /api/v1/nodes/${1}/proxy/metrics/cadvisor
           metric_relabel_configs:
             - action: replace
               source_labels: [id]
               regex: '^/machine\.slice/machine-rkt\\x2d([^\\]+)\\.+/([^/]+)\.service$'
               target_label: rkt_container_name
               replacement: '${2}-${1}'
             - action: replace
               source_labels: [id]
               regex: '^/system\.slice/(.+)\.service$'
               target_label: systemd_service_name
               replacement: '${1}'
