Docker container for Postgres 9.1 not exposing port 5432 to host

Question

I\'m trying to use a Docker container to run a PostgreSQL server, and connect with it from my host machine.

My configuration is:

• Host machine: Mac OS X

Answer 1

Your docker host is a virtual machine, which has it's own IP affffdres. You can detect this IP address by entering the following command:

docker-machine ip

The answer will be something like 192.168.99.100

When you have mapped the ports using the -p 5432:5432 switch, you will be able to connect to postgres with any tool from your dev machine using the IP address mentioned.
