Docker如何发送请求（curl – 获取，张贴）一个容器到另一个容器
GET（和POST PUT ….）请求在一个容器中使用curl到另一个容器。
$ docker ps
CONTAINER ID IMAGE COMMAND PORTS NAMES b184219cd8f6 otp_totp "./run.sh" 0.0.0.0:3000->3000/tcp totp_api c381c276593f service "/bin/sh -c" 0.0.0.0:8000->8000/tcp, 0.0.0.0:9000->9000/tcp service d0add6b1c72e mysql "/tmp/run.sh" 0.0.0.0:3306->3306/tcp mysql 当我发送请求curl -X GET http://localhost.3000到本地的totp_api container
totp_api return {'status':200}
但我想在service容器中发送请求
像// curl -X GET http://localhost:3000到totp_api service容器（ totp_api exec totp_api / bin / bash）， totp_api将返回{'status':200}到server容器
project_folder ㄴ- docker-compose.yml # service, mysql container api_folder ㄴ- docker-compose.yml # totp_api container
请一些身体告诉我一些build议
后
API /文件夹/搬运工-compose.yml
version: '3' services: totp: build: . container_name: totp_api volumes: - $PWD:/home ports: - "3000:3000" tty: true restart: always networks: - bridge networks: bridge: driver: bridge

使用dockernetworking和networking命令 ，可以确保这些容器是同一networking的一部分。
这个唯一的networking的一个副作用是容器A将知道容器B的名字：从totp_api ，你可以用它的名字来ping或者curlservice容器：
ping service
您可以：
- 在Docker撰写文件中静态执行（并重新启动新的容器）， – 在运行时testing它，将现有的运行容器添加到新的networking
