无法连接到Linux主机的MongoDB容器
我有以下的Dockerfile，只安装mongodb 3
# Start with docker's base ubuntu image FROM ubuntu:14.04.2 # Mongodb prerequisite RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10 RUN echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list # Update package sources RUN apt-get -y update # Install Mongodb binaries RUN apt-get -y install mongodb-org # Copy configuratio file COPY mongod.conf /etc/mongod.conf # Create mongo data path (will be mapped to a volume on host machine later on) RUN mkdir -p /data/db RUN chown -R mongodb:mongodb /data/db # Expose MongoDB port EXPOSE 27017 # Run mongo with mongodb user USER mongodb # Run mongod using provided configuration file ENTRYPOINT ["/usr/bin/mongod"] CMD ["--config", "/etc/mongod.conf"] 我创build的图像
sudo docker build -t mongod .
我运行容器
sudo docker run -d -P mongod
并validation它已经开始
> sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 43c75e7e44b3 mongod:latest "/usr/bin/mongod --c 3 minutes ago Up 3 minutes 0.0.0.0:49165->27017/tcp silly_mccarthy
当我从容器中运行一个mongo客户端时，它可以没有任何错误地连接：
> sudo docker exec -ti 43c75e7e44b3 bash $ mongo MongoDB shell version: 3.0.1 connecting to: test Welcome to the MongoDB shell. ....
我的主机是一个Ubuntu 14.04盒和networking接口/桥梁
docker0 Link encap:Ethernet HWaddr 63:54:7b:f3:47:33 inet addr:172.17.42.1 Bcast:0.0.0.0 Mask:255.255.0.0 .... em1 Link encap:Ethernet HWaddr c4:2f:e3:64:ae:7c inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0 .... lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 ....
从我的主机，我无法连接到mongod容器

有什么我在这里失踪？
MongoDB的默认configuration是将mongod绑定到localhost的IP地址。 在您的mongod.confsearch以下行：
bindIp = 127.0.0.1
如果你使用这样的散列注释这条线
# bindIp = 127.0.0.1
那么mongod将绑定到启动期间可用的所有 IP。 如果你这样设置一个特定的IP
bindIp = 192.168.0.42
那么mongod只绑定到这个特定的IP地址，并且只对那些可以访问指定端口上的IP的主机可用。
