Local Deployment

To locally test, deploy or play challenges with Docker, run the following

sudo apt install gcc-multilib gcc-mipsel-linux-gnu arm-linux-gnueabi g++-multilib linux-libc-dev:i386
make
docker-compose build && docker-compose up -d
Containers are viewable at localhost:PORT (view with docker-compose ps)
docker-compose kill to stop the containers
make clean to clean the source folders

GCP

You can also deploy via GCP and run the challenges in k8s. All of this is in category/challenge/Makefile to deploy.

BSidesPDX

CTF was ran during BSidesPDX 2017 on October 20th and 21st.

We used CTFd for the scoreboard hosted at BSidesPDXCTF.party.

category/challenge/aws/Makefile was used to deploy to a k8s pod in AWS. We had intended to use the GCP deployment and moved to this by creating our own cluster with the help from the above infra supporters.
