Install Xdebug for LNMP environment based on Docker - docker

Question

The LNMP(linux nginx mysql php^_^) environment based on docker, all of which I am in a container.
At present, xdebug can be used normally.
But i need enter code herexdebug.remote_host = visitor IP and our IP is constantly changing.
This is an awkward situation.
And if i set xdebug.remote_connect_back = 1 to let xdebug handle the automatic return of IP.
Docker's container is started in the default bridge mode, so the IP obtained by PHP is the bridge IP.
That is: similar to 172.0.0.1, the IP address of the real client cannot be obtained, so xdebug cannot return correctly.
Xdebug.log logs also have records:

I: Checking remote connect back address.
I: Checking header 'HTTP_X_FORWARDED_FOR'.
I: Remote address found, connecting to :9001.
W: Creating socket for ':9001', getaddrinfo: No such file or directory.
E: Could not connect to client. :-(
