Docker - cannot access container from Mac Host

Question

I cannot access a simple Docker container running locally on my mac. I can start curl localhostfrom the container and see that the Apache page is set by default, but I cannot hit it from the browser.

I am wondering if I have a problem with VirtualBox configuration or something like that. Any help in diagnosing the problem?

Dockerfile

# Build the image of ubuntu 12.04 LTS
from ubuntu:precise

# Run apt-get update
run apt-get -y update

# Install LAMP
run DEBIAN_FRONTEND=noninteractive apt-get -y install lamp-server^
run apt-get -y install vim-tiny curl wget

# Put custom scripts in the container and give proper permissions to them
add ./startup.sh /usr/local/bin/startup.sh
run chmod 755 /usr/local/bin/startup.sh

add site.vhost /etc/apache2/sites-available/site
run a2ensite site

# Expose port 80 to the host machine
expose 80

site.vhost

<VirtualHost *:80>

    ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory /var/www/>
        Options Indexes FollowSymLinks MultiViews

    </Directory>

    LogLevel warn

startup.sh

#!/bin/bash

a2dissite default
apache2ctl graceful

To start ...

I will create an image with docker build -t test1 .- which seems to work fine.

On initial setup, I run docker run -d -v $(pwd)/mysql:/tmp/mysql test1 /bin/bash -c "cp -rp /var/lib/mysql/* /tmp/mysql"to install MySQL.

Then I ran docker run -i -t -v $(pwd)/mysql:/var/lib/mysql -v $(pwd)/www:/var/www -p 8080:80 test1 /bin/bashto run the actual instance.

service apache2 start, , , . curl localhost, .
