wbsrvcs- Dockerized!

This builds off of the original wbsrvcs project, and adds docker support and a JSON topology map. Containers can be created and destroyed according to the JSON file, and requests can be sent in a chain through all of the hosts.

Installation and Usage:

Building the Docker Image

Before creating the containers, the Docker image needs to be built first. The image contains a full Ubuntu 14-based LAMP stack, as well as the wbsrcvcs PHP files.

• docker build -t pcodes/lamp . will build the image and give it the tag used in subsequent files.

Creating a Topology

A sample topology is included in the sample_top.json file. The outer name in each section represents what the container will be called. port is what host port will be mapped back to the container (i.e. 80 or 8080). No two containers should have the same port. comp is how many computations each host will do in the chain.

Python Setup

The python management script is based off of Python 3, so that's an initial dependency. Additionally, the following Python libraries must be installed:

• Docker: library that provides python bindings for interacting with docker.
• BeautifulSoup 4: Parses HTML output from cURL requests

Running the Scripts

The container_manager.py script handles all of the topology script interaction. It takes one of the following arguments.

• python3 container_manager.py -c: creates a series of containers according to the JSON file
• python3 container_manager.py -d: deletes containers specified in the JSON file
• python3 container_manager.py -t: Send a request to the containers

If a generic container is desired instead of a full topology, the create_lamp_container.sh bash script can be used instead.

• ./create_lamp_container.sh <PORT>: creates a container with the specified port
