   - AUTH_METHOD: for now only default 'passwd' based auth is supported
     - if `passwd` method is choice the 'admin' password is generated and display in container log
   - AUTH_URL: the http endpoint to authenticate the user, if option is set the AUTH_METHOD is forced to 'http'
-  - NO_AUTH: if set disable any authentication methods
