Docker容器与Docker主机xdebug冲突

Question

I have a PHP-FPM docker container (php 7.2) with a service exposing REST API inside and xdebug 2.6 installed in the container. This is the xdebug config:

zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so
xdebug.remote_enable=1
xdebug.remote_connect_back=0
xdebug.remote_autostart=0
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_port=9000
xdebug.idekey=PHPSTORM
xdebug.remote_host=hostmachine

Now I also have xdebug installed at the docker host, that is my desktop. And I'm trying to debug an API client on the docker host. The client connects to the container exposing the API. Everything hangs after sending a request from the API client to the container.

In the following code sample the assignment $test=1 is never executed if my IDE is listening for incoming debugger connections (no debug configs selected), everything hangs after stepping into $response = $this->httpClient->get('info') ( $httpClient is guzzle http 6.3 btw):

public function getInfo(): InfoInterface
    {
        $response = $this->httpClient->get('info');
        $test = 1;
    }

I was thinking that the xdebug in the container is trying to connect to my IDE, that's the reason of the hanging. But then how can I debug my API client without the container's xdebug interference?

我应该为docker容器使用不同的端口进行连接，并且/或者增加IDE中的最大调试连接，这是针对原始问题的前两个注释中建议的。
