How to access container from host using IP ADDRESS in Docker Desktop Windows 10 (esspecially with use docker compose)?

What should I do to access container via IP ADDRESS not PORT? Can I define any kind of network or bridge?

I am using standard Docker Desktop with WSL2 on Windows 10. This required to expose containers as machines not as ports.

I try this but is not works :)

This compose is very complex but you can use pure Ubuntu image to test it - not matter what image.

You can't access Linux containers by IP address from a Windows host. (...or on a MacOS host, or if you're using a VM-based Docker solution, or if the client isn't on the same host as the containers, or...) Access the containers through their published ports: instead. There's no need to ever look up a container's Docker-internal IP address.

The Docker Desktop documentation notes, under "Known limitations for all platforms":

Per-container IP addressing is not possible: The docker bridge network is not reachable from the host. However if you are a Windows user, it works with Windows containers.
