Hello, I come here because I have a problem since my company moved from Docker desktop to Rancher desktop and I didn't found a response on Internet. We have a container which need to request the host but I can't seem to ping

host.docker.internal

I tried on a new container, it does not work too. Step i've done : Firewall rule

New-NetFirewallRule -DisplayName "WSL" -Direction Inbound -InterfaceAlias "vEthernet (WSL)" -Action Allow

New container

docker run -d -p 80:80 docker/getting-started

Ping :

docker exec -it containerName sh

/ # ping -c 2 host.docker.internal

PING host.docker.internal (172.17.32.1): 56 data bytes

--- host.docker.internal ping statistics ---

2 packets transmitted, 0 packets received, 100% packet loss

Do you have an idea ? Thank's

@orange-thailand-83295 what is the entry for

host.rancher-desktop.internal host.docker.internal

in the /etc/hosts “?

Thank's for your answer. The IP is Ok for me but I don't understand why I can't request it. ping or curl 172.17.32.1 (In my case) from container should work, no ? Have I missed something ? Sorry for my bad network knowledges and thank's for your help

what IP address or network interface is you Wilfly server is listening on?

My Wildfly server is on localhost:8080 (Windows) Result of

Get-NetFirewallRule -DisplayName WSL
