How to run codeception tests in webdriver on docker so that chrome sees the project not by 172.20.0.8, but by the hostname specified in extra_hosts?

Question

Google Chrome

I am running an acceptance test on codeception.
I am using webdriver browser: chrome.

The problem is that I have several domains that chrome does not see inside the container.
That is, by host.docker.internal, by the IP of the nginx container 172.20.08, the project opens, but it needs to be opened by the domain name.
Domains in configs are thrown. If you go inside the container (docker exec -it), then curl by domain names works correctly.
Chrome connects to containers - it works by IP. So the network is all right.
But at the same time, as soon as I connect by domain name from chrome, I get the error "This site cant' be reached. ERR_CONNECTION_REFUSED"

My configs:

docker-compose.yml

Answer 1

It was worth despairing and writing here, as the decision overtook me.
The problem was with domain names ending in localhost.
Replaced everything with .local and it worked.
As I understand it, it's about docker - domainname.localhost is something special for it. The .localhost suffix is ​​handled differently.
I did not know...
