localhost in invitation urls

Hi,

I installed limesurvey via docker ( hub.docker.com/r/crramirez/limesurvey/ ).

I created a survey and generated some invitations. However the the invitation url looks like:

http://localhost/index.php/542122?token=4fxPDQGNgnpiV53&lang=de

I would like to change the url to something like

foo.example.org/index.php/542122?token=4fxPDQGNgnpiV53&lang=de

Where can I configure this?

I have version: Version 2.72.3+171020

Best regards
Thomas

I think I found a solution:
I edited config-defaults.php , I changed

$config = ' mywish-name.example.org/ ';

And now it seems to work.

Is it a good solution or is there something better?

manual.limesurvey.org/Optional_settings#Advanced_path_settings

publicurl: This should be set to the URL location of your 'public scripts'. The public scripts are those located in the "limesurvey" folder (or whatever name you gave to the directory that all the other scripts and directories are kept in). This settings is available in config.php and it is used when token emails are sent.

Never update config-default, its not done for this …

What Denis means is that all config settings should be changed in config.php, not in config-defaults.php.

What i mean : there are a specific settings done for this . Best is to use it.

(and clearlu : i'm unsure $config= string can not break something)
