1.1 创建exporter

$ docker run  -d -p 9090:9090 \
-v /data/prometheus/data:/prometheus \
-v /data/prometheus:/etc/prometheus \
--name pro prom/prometheus

暴漏9090 端口号 供prometheus 连接

1.2 创建创建配置prometheus.yml文件

$ mkdir -p /app/prometheus/data;
$ mkdir -p /app/prometheus/rules;

# my global config
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).

# Alertmanager configuration
#alerting:
#  alertmanagers:
#  - static_configs:
#    - targets: ['193.168.253.42:9093']
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
#rule_files:
#  - "node_down.yml"
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'node'
    scrape_interval: 8s
    static_configs:
      - targets: ['localhost:9100']

1.3 创建prometheus

docker run -it \
--name prometheus \
 -p 9090:9090 \
-v /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \
-d prom/prometheus

1.4 访问prometheus

http://localhost:9090
