无法连接到docker容器中的mongodb

Question

我已经构建了一个运行mongodb-instance的docker容器,该容器应该暴露给主机.但是,当我想从主机连接到mongodb容器时,连接将被拒绝.

这是我的Dockerfile:

FROM mongo:latest

RUN  mkdir -p /var/lib/mongodb && \
     touch /var/lib/mongodb/.keep && \
     chown -R mongodb:mongodb /var/lib/mongodb

ADD mongodb.conf /etc/mongodb.conf

VOLUME [ "/var/lib/mongodb" ]

EXPOSE 27017

USER mongodb
WORKDIR /var/lib/mongodb

ENTRYPOINT ["/usr/bin/mongod", "--config", "/etc/mongodb.conf"]
CMD ["--quiet"]

/etc/mongodb.conf:

这是配置文件中MongoDB的,我在那里绑定IP 0.0.0.0明确的发现这里的SO,即127.0.0.1可能是我的问题的根本原因(但不是)

systemLog:
  destination: file
  path: /var/log/mongodb/mongo.log
  logAppend: true
storage:
  dbPath: /var/lib/mongodb
net:
  bindIp: 0.0.0.0

docker容器正在运行,但是无法与主机建立连接:

host$ docker run -p 27017:27017 -d --name mongodb-test mongodb-image
host$ docker ps
$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
6ec958034a6f        mongodb-image       "/usr/bin/mongod --co"   4 seconds ago       Up 3 seconds        0.0.0.0:27017->27017/tcp   mongodb-test

找到IP地址:

host$ docker inspect 6ec958034a6f |grep IPA
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAMConfig": null,
                    "IPAddress": "172.17.0.2",

尝试连接:

host$ mongo 172.17.0.2:27017
MongoDB shell version v3.4.0
connecting to: mongodb://172.17.0.2:27017
2016-12-16T15:53:40.318+0100 W NETWORK  [main] Failed to connect to 172.17.0.2:27017 after 5000 milliseconds, giving up.
2016-12-16T15:53:40.318+0100 E QUERY    [main] Error: couldn't connect to server 172.17.0.2:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:234:13

exception: connect failed

当我进入容器时,我可以连接到mongo并成功列出测试数据库.

Answer 1

使用 localhost 而不是 ip，允许连接。

将其与暴露的端口结合起来：localhost:27017

我测试了评论中所述的解决方案，并且它有效。
