从我的本地networking连接postgreSQL + postGIS docker容器
我已经从docker中心build立了docker集装箱：
docker run --name some-postgis -e POSTGRES_PASSWORD=mysecretpassword -d mdillon/postgis docker run -it --link some-postgis:postgres --rm postgres \ sh -c 'exec psql -h "$POSTGRES_PORT_5432_TCP_ADDR" -p "$POSTGRES_PORT_5432_TCP_PORT" -U postgres' 检查：

它像我的桌面上的魅力，我可以使用psql与服务器进行交互。 它完美的作品！
psql -h 172.17.0.2 -p 5432 -U postgres
但是我想让我的同事连接数据库，我不明白它是如何工作的。
在这一点上（如果我们假设我的本地IP是192.168.0.14 ）
psql -h 192.168.0.14 -p 5432 -U postgres
不起作用…
我发现了一些链接：
- https://developer.ibm.com/recipes/tutorials/networking-your-docker-containers-using-docker0-bridge/
- http://blog.oddbit.com/2014/08/11/four-ways-to-connect-a-docker/
但它仍然清楚。
你需要做的是运行容器时的端口映射。
docker run -p 5432:5432 --name some-postgis -e POSTGRES_PASSWORD=mysecretpassword -d mdillon/postgis
这将映射主机上的5432（左侧）到容器上的5432（右侧）。 只要您的IP可以从他的机器上访问，您的同事就可以访问数据库
