A plugin for CTFd which allow your users to launch a standalone instance for challenges.
- Provide a new challenge type - dynamic_docker.
- The player can launch an instance for these challenge on the challenge board by one click.
- Every instance has a unique flag.
- Admin can manage the instance at the admin panel.
- You should init docker swarm, and add your node to it. And name them with following command:
docker node update --label-add name=windows-1 ****
docker node update --label-add name=linux-1 ****
Name of them should begin with windows- or linux-.
- Copy this folder to your ctfd plugins folder. Make sure the folder name is 'ctfd-whale'.
- Deploy frp on your servers, and you should make sure CTFd can access frpc admin API directly.
- And also make sure docker API is accessible to CTFd, you should create a network in docker called 'ctfd_frp-containers' which allow frp redirect traffic to challenge instances.
- Configure this plugin on the admin panel.
- Now you may create a challenge, choose the challenge type - dynamic_docker and fill the form.
- Click the preview button, then you can launch an instance for this challenge.
- Enjoy it:)
