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

I had a similar problem working in a VMWare virtual machine with Lubuntu. The VM had been paused and then was restarted. The PostgreSQL Docker container was correctly mapped and listening on localhost:5432, but I always got:

psql: server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.

Restarting the VM solved the problem in my case.
