docker search alertmanager

docker pull docker.io/prom/alertmanager:latest

docker run -d -p 9093:9093 -v /root/alertmanager/config.yml:/etc/alertmanager/config.yml --name alertmanager docker.io/prom/alertmanager:latest

可以举个例子，这是关于监控kubernetes的报警设置，当然，关于其他内容的详细设置日后会做详解

groups:
- name: example-rules
  interval: 30s # defaults to global interval
  rules:
  - alert: Node Down
    expr: up{job="kubernetes-nodes"} == 0
    labels:
      severity: error
    annotations:
      miqTarget: "ContainerNode"
      severity: "HIGH"
      message: "{{$labels.instance}} is down"
  - alert: "Too Many Pods"
    expr: sum(kubelet_running_pod_count) > 50
    labels:
      severity: error
    annotations:
      miqTarget: "ExtManagementSystem"
