MongoDB docker image connection issue
问题
我尝试在本地运行一个运行MongoDB的Docker容器，但遇到了一些问题。
我使用的是MacOS，这是我的Docker文件：
FROM mongo:4.4.10
RUN apt-get update && \
apt-get install -y mongodb-database-tools
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD admin
EXPOSE 27017
CMD ["mongod", "--bind_ip_all"]
但当我尝试在容器内部连接Mongo时，我得到了以下错误：
root@1820984d904c:/# mongo
MongoDB shell version v4.4.10
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:374:17
@(connect):2:6
exception: connect failed
exiting with code 1
我是这样运行容器的：
docker run -it -p 27017:27017 --rm --name containername imagename bash
有任何建议吗？
谢谢

Im try to run a local docker container running MongoDB but I got some issues.
Im using MacOS and this is my docker file:
FROM mongo:4.4.10
RUN apt-get update && \
apt-get install -y mongodb-database-tools
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD admin
EXPOSE 27017
CMD ["mongod", "--bind_ip_all"]
But when I try to connect in mongo inside the container I got:
root@1820984d904c:/# mongo
MongoDB shell version v4.4.10
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

@(connect):2:6
exception: connect failed
exiting with code 1
Im running the container like this:
docker run -it -p 27017:27017 --rm --name containername imagename bash
Any ideas?
Thanks

你没有在docker run命令中启动Mongo，而是启动了bash。
根据https://docs.docker.com/engine/reference/run/#overriding-dockerfile-image-defaults：
> CMD（默认命令或选项）
>
> 回忆一下Docker命令行中的可选COMMAND：
>
> docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]
> 这个命令是可选的，因为创建IMAGE的人可能已经在Dockerfile CMD指令中提供了默认的COMMAND。作为操作者（从该IMAGE运行容器的人），你可以通过指定一个新的COMMAND来覆盖那个CMD指令。
所以，使用以下命令启动你的Docker：
docker run -p 27017:27017 --rm --name containername imagename
然后使用以下命令进入容器的bash环境：
docker exec -it containername bash
英文:
You are not starting mongo with your docker run command. You are starting bash instead.
From https://docs.docker.com/engine/reference/run/#overriding-dockerfile-image-defaults:
> CMD (default command or options)
>
> Recall the optional COMMAND in the Docker commandline:
>
> docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]
> This command is optional because the person who created the IMAGE may have already provided a default COMMAND using the Dockerfile CMD instruction. As the operator (the person running a container from the image), you can override that CMD instruction just by specifying a new COMMAND.
So start your docker with
docker run -p 27017:27017 --rm --name containername imagename
Then bash in to the container with
docker exec -it containername bash
