docker - 为什么我不能在centos7上真正运行docker telegraf容器？

Question

首先，我通过docker client运行了一个influxdb容器。现在，我想运行一个telegraf容器，该容器收集容器的数据和虚拟机管理程序主机的数据，例如cpu \ mem \ diskio等。但是我失败了， docker 日志显示我无法将自定义telegraf.conf映射到容器的/etc/telegraf/telegraf.conf。

基本信息 :

docker版本:1.13.1

centos版本:centos7

内核版本:3.10.0-957.12.2.el7.x86_64

我试过的命令:

Influxdb:
docker 网络创建influxdb
docker运行-d -p 8086:8086 -p 8083:8083 --name = influxdb --net = influxdb docker.io/influxdb

Telegraf:
docker 运行-d --name = telegraf --net = influxdb \
-e HOST_PROC = / host / proc \
-v / proc:/ host / proc:ro \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /root/telegraf.conf:/etc/telegraf/telegraf.conf:ro \
telegraf

您可以尝试此docker-compose.yaml

version: '3'
services:
  influxdb:
    image: influxdb:1.7.8
    container_name: influxdb
    volumes:
      # Mount for influxdb data directory
      - ./monitoring/influxdb:/var/lib/influxdb
      # Mount for influxdb configuration
      - ./monitoring/influxdb/config/:/etc/influxdb/
    ports:
      - "8086:8086"
      - "8082:8082"
      - "8089:8089/udp"

  telegraf:
    image: telegraf:1.12.2
    container_name: telegraf
    environment:
      HOST_MOUNT_PREFIX: "/hostfs"
      HOST_PROC: "/hostfs/proc"
      HOST_SYS: "/hostfs/sys"
      HOST_ETC: "/hostfs/etc"
    volumes:
      # Mount for telegraf configuration
      - ./monitoring/telegraf/:/etc/telegraf/
      - /:/hostfs:ro
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - influxdb

  chronograf:
    image: chronograf:1.7.14
    container_name: chronograf
    environment:
      RESOURCES_PATH: "/usr/share/chronograf/resources"
    volumes:
      # Mount for chronograf database
      - ./monitoring/chronograf/data/:/var/lib/chronograf/
    ports:
      - "8890:8888"
    depends_on:
      - influxdb
      - telegraf
