docker - Docker组成，单独运行时无法与裸端口通信吗？

Question

我分别运行了两项服务

docker-compose run --service-ports django /bin/bash
docker-compose run --service-ports other /bin/bash

尽管我可以在 docker ps中看到端口，但是服务无法与另一个服务中的公开端口通信。

$ docker ps

docker-compose.yml有

 services:
  django:
    restart: always
    build:
      context: .
      dockerfile: ./compose/production/django/Dockerfile
    image: littlehome
    depends_on:
      - other
      - nginx
    env_file:
      - ./compose/.envs/production/postgres
    # command: /app/compose/production/django/uwsgi.sh
    ports:
      - "0.0.0.0:10011:10011"

 other:
    build:
      context: .
      dockerfile: ./compose/production/other/Dockerfile
    image: littlehome_other
    # depends_on:
    #   - postgres
    expose:
      - "9200"
      - "6379"
      - "6380"
    volumes:
      - ~/.bash_history:/root/.bash_history

我想让 django与 other:9200交流
docker network inspect zibann-reservation_default显示

        }
    },

服务是elasticsearch，客户端正在尝试通过 'http://other:9200/reviewmeta_index/_count'连接到elasticsearch可以吗？

Answer 1

确保它们连接到同一网络。

使用检查您的网络docker network ls (使用此处的值稍后连接)

检查您的容器正在使用哪个网桥: docker 网络检查网桥

并连接正确的网络: docker网络连接default-bridge zibann-reservation_django_run_3 (default-bridge是您要连接的网络。当然可以是任何网络)

可以在此处找到更多详细信息:https://docs.docker.com/network/network-tutorial-standalone/#use-the-default-bridge-network和https://docs.docker.com/engine/reference/commandline/network_connect/#related-commands
