Build

Steps to build a Docker image:

####1. Clone this repo

    $git clone https://github.com/lidaco/cent4j.git

####2. Build the image

    $cd cent4j
    $docker build -t="lidaco/cent4j" ./

    This will take a few minutes.

####3. Run the image's default command, which should start everything up The -p option forwards the container's port 80 to port 8083 on the host. (Note that the host will actually be a guest if you are using boot2docker, so you may need to re-forward the port in VirtualBox.)

    $docker run -it -p="8083:80" lidaco/cent4j /bin/bash
    $/bin/startup.sh

####4. Access Webapp via http://localhost:8083/ on your host machine

    open http://localhost:8083/

####You can also login to the image and have a look around with

    $docker run -it lidaco/cent4j /bin/bash
