無法連接到mongodb容器主機

Question

我試圖連接到mongodb容器，但是它不起作用，無法識別主機。

這是我帶有服務的docker-compose.yml文件：

  version: '3'
  services:

  mongodb:
    build:
      context: .
      dockerfile: docker/mongodb/Dockerfile
    restart: always
    environment:
      DATABASE: database
      USERNAME: user
      PASSWORD: pass
    ports:
      - '5100:27017'
    volumes:
      - ./data/db:/data/db

這是我的mongodb的dockerfile：

FROM mvertes/alpine-mongo:4.0.5-0

ENV MONGO_INITDB_DATABASE: ${DATABASE}
ENV MONGO_INITDB_ROOT_USERNAME: ${USERNAME}
ENV MONGO_INITDB_ROOT_PASSWORD: ${PASSWORD}

COPY ./docker/mongodb/init.js /docker-entrypoint-initdb.d

CMD ["mongod"]

EXPOSE 27017

我正在嘗試從Spring建立連接，但是找不到服務，這是我的屬性：

spring.data.mongodb.host=mongodb
spring.data.mongodb.port=5100
spring.data.mongodb.username=user
spring.data.mongodb.password=pass
spring.data.mongodb.database=database

而且我正在嘗試與robo3T建立連接，問題是相同的：

Address: mongodb://mongodb
port:5100

春天的錯誤說：

com.mongodb.MongoSocketException: mongodb: unknown name or service

在robo3T中說：

Cannot connect to the MongoDB at mongodb:5100.

Error:
Network is unreachable.

我究竟做錯了什么？

編輯：我的容器日志：

docker-compose.yml這一部分意味着您想將在端口27017上工作的容器在端口5100上公開給公眾，以便任何人都可以訪問localhost或public ip，但是mongodb作為主機一詞只能在容器之間識別在docker網絡內部，因此，如果您在同一網絡中有另一個容器，它可以作為主機名和端口27017到達mongodb上的mongodb

ports:
  - '5100:27017'

根據mongodb日志，您遇到以下問題：

** WARNING: This server is bound to localhost. Remote systems will be unable to connect to this server. Start the server with --bind_ip <address> to specify which IP 

因此，您需要使用--bind_ip 0.0.0.0啟動mongodb ，以便可以從容器外部訪問它。 將您的CMD更改為以下內容：

CMD [ "mongod", "--bind_ip", "0.0.0.0" ]

或者從您的Dockerfile中刪除CMD ，它會回退到基礎映像的原始CMD ， 與上面的相同 。

從MongoDB 3.6開始，默認情況下mongod綁定到localhost。 請參閱默認綁定到本地主機 。
