VeraDemo - Blab-a-Gag

About

Blab-a-Gag is a fairly simple forum type application which allows:

Users can post a one-liner joke.
Users can follow the jokes of other users or not (listen or ignore).
Users can comment on other users messages (heckle).

URLs

/feed shows the jokes/heckles that are relevant to the current user.
/blabbers shows a list of all other users and allows the current user to listen or ignore.
/profile allows the current user to modify their profile.
/login allows you to log in to your account
/register allows you to create a new user account
/tools shows a tools page that shows a fortune or lets you ping a host.

Running the Project

Verify you have docker installed via docker ps

Download the project via

git clone https://github.com/YuqiHuai/verademo

Navigate to the root directory of the project via
```
cd verademo
```
Build the project via
```
docker build -t verademo .
```
This command looks at the Dockerfile in your current working directory (i.e., after you run cd verademo, your current working directory is verademo) and builds a docker image based on that Dockerfile. Docker image allows docker to create a container, a container is a lightweight virtual machine.
Run the project via
```
docker run -p 8080:8080 -it verademo
```
This command creates a container based on the image named verademo (i.e., the one you built in the previous step), and binds port 8080 of your local machine to port 8080 of the container, so if you open a browser and go to http://127.0.0.1:8080, you are viewing the content from port 8080 of the container.
Navigate to: http://127.0.0.1:8080

Workflow when doing the assignment

The assignment asks you to run the project, understand some of the exploits, and try to fix them. Therefore you are expected to read the source code of the project, and make some modifications to mitigate the threat.

So the first thing you do is to run git clone ... to download the project. After doing so, you can find the source code of the project under verademo/app.

You build the project by running docker build ... , run the project by running docker run ..., and go to http://127.0.0.1:8080 to explore the web app.

After you have explored enough and understood the exploits, you modify the source code in verademo/app to mitigate some of the threats. Each time you modify the source code you need to rebuild the project by running docker build ... and rerun the project by running docker run ... to see the effect of your changes.

You must rebuild and rerun the project to see your changes.

Quick Commands using Makefile

To simplify commands for using Docker, a Makefile is provided with the following commands:

make clean will stop and remove all docker containers
make build will build the docker image
make run will run the built docker image
make restart will rebuild the image and restart the container
