When creating your cluster, you can specify a domain with the
kCTF will then automatically create domain names for challenges of the form:
You might want to use custom domains for some of your challenges, for example:
For TCP based challenges, all you need to do is to create a CNAME DNS entry from $cooldomain to $chal_name.$kctf_domain.
For HTTPS based challenges, you also need to add a CNAME entry (pay attention to the -web suffix) and in addition, list the domain in the port configuration of the challenge:
apiVersion: kctf.dev/v1 kind: Challenge metadata: name: web spec: deployed: true powDifficultySeconds: 0 network: public: true ports: - protocol: "HTTPS" targetPort: 1337 domains: - "cooldomain.com"
With this, kCTF will automatically create a certificate for you and attach it to the challenge’s LoadBalancer.
