CTF

Repo for messing around with capture the flag (CTF) challenges.

Toolkit Container

1. Set up Lima (brew install lima) for Docker (x86) on MacOS.

   limactl create \
     --name=default \
     --arch=x86_64 \
     --mount-type=reverse-sshfs \
     template://docker

2. Build an x86 Docker image on MacOS using Lima.

   lima docker build -t npho/ctf:0.1 .

   A: You can use lima as a shortcut for limactl shell.

   B: Setting LIMA_INSTANCE=default you can avoid having to specify the instance name. Useful if it's not default.

3. Run the x86 Docker image on MacOS using Lima.

   lima docker run -v $(pwd):/home/ubuntu/ctf -it npho/ctf:0.1
