Switch xdebug remote port to 9000

[ihor-sviziev]

Right now Dockergento using custom 9001 port for xdebug.

https://github.com/ModestCoders/dockerfiles/blob/df68a4521976c77c763de4b340edd09f69dbfdeb/php/7.1-fpm/conf/xdebug.ini#L6

Is there any reason to have custom port, instead of default one - 9000? I think switching to 9000 port will lead to easier xdebug configuration

Hi @ihor-sviziev I think there is no specific reason for using this port, but maybe @jalogut can confirm that!

If you try the 9000 port and find no issues at all please tell us and we could change it as default! Of this way you won't need to update it in phpstorm settings.

Hi @ihor-sviziev well actually there is a reason for that. Our php images use port 9000 for FastCGI connections.

See line 36 here: https://github.com/ModestCoders/dockerfiles/blob/master/php/7.2-fpm/conf/www.conf

I think it's not a big deal and not really related.

1. It listens 9000 port on php-fpm container and not forwarded to host machine
2. nginx actually working with php fpm using unix socket, I guess using 9000 port there could be safely removed

Any updates?

Hi @ihor-sviziev If phpstorm uses port 9000 by default, and we don't need to use it for fastcgi because nginx is already using unix socket I don't see any reason to move XDebug to port 9001.

I'll work on it! Thanks!

Basically in xdebug 3 there was changed default port to 9003, it will be switched to this new port in ModestCoders/dockerfiles#21 and #83.
I'm closing this issue as not relevant anymore.
