go-zero 的 BFF 找不到已经存储在 ETCD 数据库中的 RPC 服务的密钥

Question

我正在使用Go语言框架Go-Zero开发一个个人项目。在 Golang 端，有四个服务：BFF（API 服务），以及三个 RPC 服务，分别为 postsRpc、gauthRpc、usersRpc，BBF 依赖于三个 Rpc 服务，如下：

1. BFF api 服务配置：

Name: app
Host: 0.0.0.0
Port: 8888

UserRpc:
  Etcd:
    Hosts:
    - 127.0.0.1:2379
    Key: users.rpc

GauthRpc:
  Etcd:
    Hosts:
    - 127.0.0.1:2379
    Key: gauth.rpc

PostsRpc:
  Etcd:
    Hosts:
    - 127.0.0.1:2379
    Key: posts.rpc

2. 三个Rpc服务配置：

authRpc

Name: gauth.rpc
ListenOn: 0.0.0.0:8080
Etcd:
  Hosts:
  - 127.0.0.1:2379
  Key: gauth.rpc

帖子 Rpc

Name: posts.rpc
ListenOn: 0.0.0.0:8082
Etcd:
  Hosts:
  - 127.0.0.1:2379
  Key: posts.rpc

用户Rpc

Name: users.rpc
ListenOn: 0.0.0.0:8081
Etcd:
  Hosts:
  - 127.0.0.1:2379
  Key: users.rpc

我在本地机器上运行 docker-compose，yaml 文件内容如下：

version: '3.1'

services:
  globaldb:
    image: mysql:8.0
    restart: always
    command: '--default-authentication-plugin=mysql_native_password'
    healthcheck:
      test: ['CMD-SHELL', 'mysqladmin ping -h 127.0.0.1 --password="$$(cat /run/secrets/db-password)" --silent']
      interval: 3s
      retries: 5
    ports:
      - "23306:3306"
    volumes:
      - ./db/db-data:/var/lib/mysql
    environment:
      MYSQL_DATABASE: globalfun
      MYSQL_ROOT_PASSWORD: root
    networks:
      - globalnet
  globalrd:
    image: redis:latest
    restart: always
    ports:
      - "26379:6379"
    command: redis-server --save 20 1 --loglevel warning --requirepass globalroot
    volumes:
      - ./rd:/data
    networks:
      - globalnet
  globaletcd:
    image: bitnami/etcd:latest
    restart: always
    ports:
      - "2379:2379"
    environment:
      - ALLOW_NONE_AUTHENTICATION=yes
    networks:
      - globalnet
  globalmongo:
    image: mongo:7.0.3
    container_name: globalmongo
    ports:
      - 27017:27017
    environment:
      - MONGO_INITDB_DATABASE=globalfun
#      - MONGO_INITDB_ROOT_USERNAME=admin
#      - MONGO_INITDB_ROOT_PASSWORD=globalroot
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=globalroot
    volumes:
      # seeding scripts
      - ./mongo-entrypoint:/docker-entrypoint-initdb.d
      # named volumes
      - ./mongodata/mongodb:/data/db
      - ./mongodata/mongoconfig:/data/configdb
    networks:
      - globalnet
networks:
  globalnet:
    driver: bridge

当我运行三个RPC服务时，ETCD有以下三个键：

@35458f0c3201:/opt/bitnami/etcd$ etcdctl get "" --prefix
gauth.rpc/7587875305045080324
192.168.31.119:8080
posts.rpc/7587875305045080330
192.168.31.119:8082
users.rpc/7587875305045080327
192.168.31.119:8081

但是当我运行 BFF 主 go 文件时：

app.go

，我感到恐慌：

API server listening at: 127.0.0.1:2913
2023/12/13 21:05:21 rpc dial: etcd://127.0.0.1:2379/users.rpc, error: context deadline exceeded, make sure rpc service "users.rpc" is already started

Debugger finished with the exit code 0

但是

users.rpc

密钥已经在etcd中，为什么BFF api服务找不到密钥？ 这真的让我感到沮丧，如果有人能找到恐慌原因，请给我一些建议。

Answer 1

我找到了BFF找不到

users.rpc

键的原因，是我本机代理环境http_proxy/https_proxy设置了值

127.0.0.1:7890

导致的，而代理ip与docker容器ip不同，所以当我删除http_proxy/https_proxy路径时， 有效！ 谢谢大家。
