Docker image for PostgreSQL
Get it running:
$ docker-compose up
Testing the running PostgreSQL
To test the running container we can use any client, even the commandline one:
psql -h localhost -p 5432 -U pguser -W pgdb
When you are prompted for password, type: pguser
Please note that localhost is only valid if you are running Docker on Ubuntu. If you are an OSX user, you need to discover the correct ip using: boot2docker ip
