docs: AUTHORIZER_URL is required in 2.4.0 - #11
Merged
Conversation
#764 made --url mandatory in Authorizer 2.4.0 — the server exits at
boot without it. This deploy path passed the flag but treated the value as
optional, so a default deploy produces a server that will not start.
The Dockerfile already passes --url="${AUTHORIZER_URL}", so an unset var
becomes --url="" and the server exits with a clear message. Documents it
in the required-variables table so operators set it up front.

Why
authorizerdev/authorizer#764 made
--urlmandatory in Authorizer 2.4.0 —validateAuthorizerURLrefuses startup without it. This deploy path already passed the flag, but treated the value as optional, so a default deploy produces a server that exits at boot.Without
--urlthe server derives its own host from request headers, so a forgedHostmakes a genuine password-reset link point at an attacker-controlled domain (CWE-640). Mandatory is the fix; these repos had not caught up.Related

The Dockerfile already passes
--url="${AUTHORIZER_URL}", so an unset variable becomes--url=""and the server exits with its own clear message — the failure is loud, just undocumented. Adds it to the required-variables table so operators set it before the first deploy rather than after a failed one.
