新建promethues配置文件，命名为prometheus.yml。这里除了抓取prometheus自身的数据，还抓取了宿主机（MacOS）的node_exporter数据。

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['prometheus:9090']

  - job_name: 'node_exporter'
    static_configs:
    - targets: ['host.docker.internal:9100']

remote_write:
  - url: "http://telegraf:31234/receive"

新建telegraf的配置文件telegraf.conf，负责将数据转发给influxdb

[[inputs.http_listener_v2]]
## Address and port to host HTTP listener on
service_address = ":31234"
## Path to listen to.
path = "/receive"
## Data format to consume.
data_format = "prometheusremotewrite"

[[outputs.influxdb_v2]]
urls = ["http://influxdb:8086"]
token = "my-super-secret-auth-token"
organization = "myorg"
bucket = "mybucket"
