CTFd-Setup

Version your CTFd setup configuration.

CTFd does not have the concept of configuration file, leading to deployment complications and the impossibility to version configurations. This is problematic for reproducibility or sharing configuration for debugging or replicating a CTF infrastructure.

Moreover, the setup API does not exist, so we had to map it to what the frontend calls in go-ctfd.

To fit those gaps, we built ctfd-setup on top of the CTFd API. This utility helps setup a CTFd instance from a YAML configuration file, CLI flags and environment variables. Thanks to this, you can integrate it using GitHub Actions, Drone CI or even as part of your IaC provisionning.

How to use

For the CLI configuration, please refer to the binary's specific API through ctfd-setup --help. In use of IaC provisionning scenario, the corresponding environment variables are also mapped to the output, so please refer to it.

GitHub Actions

To improve our own workflows and share knownledges and tooling, we built a GitHub Action: ctfer-io/ctfd-setup. You can use it given the following example.

name: 'My workflow'

on:
  push:
    branches:
      - 'main'

jobs:
  my-job:
    runs-on: 'ubuntu-latest'
    steps:
      - name: 'Setup CTFd'
        uses: 'ctfer-io/[email protected]'
        with:
          url: ${{ secrets.CTFD_URL }}
          appearance_name: 'My CTF'
          appearance_description: 'My CTF description'
          admin_name: ${{ secrets.ADMIN_USERNAME }}
          admin_email: ${{ secrets.ADMIN_EMAIL }}
          admin_password: ${{ secrets.ADMIN_PASSWORD }}
          # ... and so on (non-mandatory attributes)

Drone CI

This could also be used as part of a Drone CI use ctferio/ctfd-setup.

kind: pipeline
type: docker
name: 'My pipeline'

trigger:
  branch:
  - main
  event:
  - push

steps:
  # ...

  - name: 'Setup CTFd'
    image: 'ctferio/[email protected]'
    settings:
      url:
        from_secret: CTFD_URL
      appearance_name: 'My CTF'
      appearance_description: 'My CTF description'
      admin_name:
        from_secret: ADMIN_USERNAME
      admin_email:
        from_secret: ADMIN_EMAIL
      admin_password:
        from_secret: ADMIN_PASSWORD
      # ... and so on (non-mandatory attributes)
