kubernetes + traefik + prometheu

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

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}'
