Docker 安装Prometheus

1.拉取镜像

[root@localhost ~]# docker pull prom/prometheus

2.创建目录

[root@localhost ~]# mkdir -p /data/prometheus
[root@localhost ~]# cd /data/prometheus

创建prometheus.yml文件

[root@localhost ~]# vim prometheus.yml

# 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:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "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: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    # 这里改为服务器ip以及分配的端口号
    - targets: ['xxx.xxx.xxx.xxx:9090']

3.创建容器

[root@localhost ~]# docker run --name prometheus -d -p 9090:9090  -v /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml -v /data/prometheus/rules:/etc/prometheus/rules prom/prometheus --config.file=/etc/prometheus/prometheus.yml  --web.enable-lifecycle

4.开放防火墙端口

[root@localhost ~]# firewall-cmd --zone=public --add-port=9090/tcp --permanent
[root@localhost ~]# firewall-cmd --reload

5.测试

访问系统 http://ip:9090。
