Viktor wants Forgejo open for anyone to sign up, but without bot/spam
account floods. Flip the deployment from OAuth-only registration
(ALLOW_ONLY_EXTERNAL_REGISTRATION=true) to allowing native local
sign-up, and add two bot gates on the registration form:
- Cloudflare Turnstile captcha (CAPTCHA_TYPE=cfturnstile). The widget
is managed in Terraform (turnstile.tf) via the CF Global API key, so
the sitekey/secret are IaC, not a dashboard artifact.
- Mandatory email confirmation (REGISTER_EMAIL_CONFIRM=true). Wire the
Forgejo mailer to the cluster mailserver as noreply@viktorbarzin.me
(mail.viktorbarzin.me:587 STARTTLS), reusing the same Vault-sourced
credential Authentik uses (email-secret.tf ESO -> secret/authentik
smtp_password).
Existing Authentik OAuth2 login is unchanged (additive). Deployment env
appended (not inserted) so the diff stays purely additive; a reloader
annotation rolls the pod on secret rotation.
Verified live: signup page renders the Turnstile widget, mailer delivers
a test message end-to-end, Forgejo healthy, plan-to-zero after apply.
