Question

docker-compose.yml：服务已启动并正在运行。

version: '3'
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
      - 9090:9090
    volumes:
      - ./prometheus/conf:/etc/prometheus
#      - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
      - ./alertmanager/alert_rules.yml:/alertmanager/alert.rules.yml
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'

  alertmanager:
    image: prom/alertmanager:latest
    container_name: alertmanager
    ports:
      - 9093:9093
    volumes:
      - ./alertmanager/:/etc/alertmanager/
    command:
      - '--config.file=/etc/alertmanager/alertmanager.yml'
      - '--storage.path=/alertmanager'

prometheus.yml：具有目标和警报目标集的Prometheus配置文件。 alertmanager目标网址工作正常。

global:
  scrape_interval: 15s
  scrape_timeout: 10s
  evaluation_interval: 15s
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - 10.10.5.14:9093
    scheme: http
    timeout: 10s
    api_version: v1
rule_files:
  - "/alertmanager/alert.rules:/alertmanager/alert.rules"
scrape_configs:
  - job_name: 'blackbox'
    metrics_path: /probe
    params:
      module: [http_2xx]
    static_configs:
      - targets:
        - "google.com"
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: localhost:9115

alert.rules：标准警报规则。

groups:
- name: example
  rules:

  # Alert for any instance that is unreachable for >1 minutes.
  - alert: InstanceDown
    expr: up == 0
    for: 1m

alertmanager.yml：用于通过gmail smtp发送警报的代码。

route:
  group_by: [Alertname]
  # Send all notifications to me.
  receiver: email-me

receivers:
- name: email-me
  email_configs:
  - to: anyemail.com
    from: senderlogin@gmail.com
    smarthost: smtp.gmail.com:587
    auth_username: "senderlogin@gmail.com"
    auth_identity: "senderlogin@gmail.com"
    auth_password: "password"

问题：所有容器都可以使用，但是prometheus规则中没有任何规则。字母也没有相应地出现。我不明白我错过了什么。欢迎任何提示。谢谢。 enter image description here enter image description here

Answer 1

从prometheus容器的角度来看，Alertmanager不在本地主机上，网络在容器中命名空间，因此您需要使用DNS发现联系Alertmanager来查找当前容器IP。通过compose，将自动为服务名称配置DNS，在这种情况下为alertmanager：

alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - alertmanager:9093

无法通过Alertmanager发送电子邮件
