我有一个以下的撰写文件命名为d docker-comment. yaml：

version: '3.7'

networks:
  back-tier:

services:

  prometheus:
    image: prom/prometheus:v2.36.2
    volumes:
      - ./prometheus/:/prometheus/
    ports:
      - 9090:9090
    networks:
      - back-tier
    restart: always

文件夹结构如下所示：

[！[在此处输入图像描述][1]][1]

prometheus. yml看起来像这样：

# Sample Prometheus config
# This assumes that your Prometheus instance can access this application on localhost:8080

global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

scrape_configs:
  - job_name: 'spring boot scrape'
    metrics_path: '/actuator/prometheus'
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:8080']

我已经开始了

docker-compoe up -d

我有Spring启动应用程序启动本地：当我打http://localhost:8080/actuator/prometheus

我看到以下（我的自定义指标）：

....
# HELP greeting_time_seconds Time taken to return greeting
# TYPE greeting_time_seconds summary
greeting_time_seconds{class="com.tutorialworks.demos.springbootwithmetrics.GreetingController",exception="none",method="greeting",quantile="0.5",} 8.8064E-5
greeting_time_seconds{class="com.tutorialworks.demos.springbootwithmetrics.GreetingController",exception="none",method="greeting",quantile="0.9",} 0.022018048
greeting_time_seconds_count{class="com.tutorialworks.demos.springbootwithmetrics.GreetingController",exception="none",method="greeting",} 9.0
greeting_time_seconds_sum{class="com.tutorialworks.demos.springbootwithmetrics.GreetingController",exception="none",method="greeting",} 0.022103
# HELP greeting_time_seconds_max Time taken to return greeting
# TYPE greeting_time_seconds_max gauge
greeting_time_seconds_max{class="com.tutorialworks.demos.springbootwithmetrics.GreetingController",exception="none",method="greeting",} 0.0212423
....

但当我试图进入普罗米修斯

http://localhost:9090/

我没有看到任何greeting_time_seconds指标

看来普罗米修斯无法收集我的指标。

我检查了http://localhost:9090/config

它的反应是：

global:
  scrape_interval: 15s
  scrape_timeout: 10s
  evaluation_interval: 15s
alerting:
  alertmanagers:
  - follow_redirects: true
    enable_http2: true
    scheme: http
    timeout: 10s
    api_version: v2
    static_configs:
    - targets: []
scrape_configs:
- job_name: prometheus
  honor_timestamps: true
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  follow_redirects: true
  enable_http2: true
  static_configs:
  - targets:
    - localhost:9090

所以看起来它没有从本地文件夹中看到我的配置。

我怎样才能修好它？

我已经更正了docker-comort文件中的卷：…… prometheus：image：prom/prometheus：v2.36.2卷：-./prometheus/：/etc/prometheus/……

现在http://localhost:9090/

使用我提供的配置进行响应：

global:
  scrape_interval: 15s
  scrape_timeout: 10s
  evaluation_interval: 15s
scrape_configs:
- job_name: spring boot scrape
  honor_timestamps: true
  scrape_interval: 5s
  scrape_timeout: 5s
  metrics_path: /actuator/prometheus
  scheme: http
  follow_redirects: true
  enable_http2: true
  static_configs:
  - targets:
    - localhost:8080

根据DazWilkin的建议，我已经更新了撰写文件

version: '3.7'

#networks:
#  back-tier:

services:

  prometheus:
    image: prom/prometheus:v2.36.2
    volumes:
      - ./prometheus/:/etc/prometheus/
    ports:
      - 9090:9090
#    networks:
#      - back-tier
    network_mode: "host"
    restart: always

组合后，我看到容器是活的，但URLlocalhost:9090现在无法访问
