host.docker.internal alternative

[electriquo]

I am migrating from Docker Desktop to Rancher Desktop (RD). Right now, I am using RD version 1.0.1 with dockerd/moby.
Is there any alternative to host.docker.internal

I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

$ docker run --rm curlimages/curl -vs http://host.docker.internal:8000
* Could not resolve host: host.docker.internal
* Closing connection 0

Is it missing from Rancher Desktop?
What is the alternative?

We define the name inside the VM, but it currently does not resolve from inside containers. lima-vm/lima#622 will add this for macOS and Linux, and #1302 will provide this on Windows.

In the meanwhile, is there any alternative?

yes, this will work for Linux and macOS, but not for Windows.
