Anubis (https://anubis.techaro.lol) is a lightweight proof-of-work
challenge that protects web services from AI crawlers and scrapers.
Changes:
- Add Anubis as an extraContainers sidecar in the Gitea HelmRelease
- Listens on :8080, proxies to Gitea at http://localhost:3000
- DIFFICULTY=4 (default; tune up to increase challenge strength)
- SERVE_ROBOTS_TXT=true (Anubis manages robots.txt)
- OG_PASSTHROUGH=true (OpenGraph bots pass through for link previews)
- Signs challenges with ED25519 key from 'anubis-key' secret
- Add anubis port (8080) to Gitea service via additionalPorts
- Update Ingress to route to the 'anubis' port instead of 'http'
- Add anubis-secret.yaml placeholder with creation instructions
One-time setup required before applying:
kubectl create secret generic anubis-key \
--namespace gitea \
--from-literal=ED25519_PRIVATE_KEY_HEX=$(openssl rand -hex 32)
