等效于 Rancher Desktop 中 Docker 桌面的 'host.docker.internal'

Question

For Docker Desktop inside a container, the DNS name host.docker.internal resolves to an IP address allowing network access to the host. Is there something similar when using Rancher Desktop?

Assuming a running container (eg the alpine image) in Docker Desktop it's possible run

docker exec alpine-container ping -c 2 host.docker.internal

Answer 1

There is an open GitHub issue for it [0]. As a workaround until this is closed, a hint from a member of Rancher Labs might help (at least when running Rancher Desktop on Linux/macOS):

I don't think we have a symbolic name for it, but the host is always (on Linux and macOS) accessible via 192.168.5.2, which is the qemu gateway address. [1]
