备注:直接访问node_exporter 是可以访问的

2、使用环境:
node_exporter版本 1.0.1 ;
系统:centos7

配置文件prometheus.yml :

[root@localhost prometheus-tls]# cat prometheus.yml 
global:
  scrape_interval:     15s
  evaluation_interval: 15s
scrape_configs:
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'node_exporter'
    scheme: https
    tls_config:
      ca_file: node_exporter.crt
    static_configs:
    - targets: ['localhost:9100']

不要使用localhost,因为使用localhost或者127.0.0.1都是去访问普罗米修斯容器的本身;你要使用宿主机ip+端口

感谢老师的帮助,老师太厉害了,问题已解决

这里说的是prometheus.yml 文件中需要使用ip
