Hi! I'm testing this workaround with the latest versions of Kathara/Docker Desktop on Mac OS and it seems it isn't working, could it be?
My lab's code is here: https://github.com/redesunlu/kathara-labs/tree/adding_browser_http3_lab/kathara-lab_http3
Thank you!
Hi @marcelofernandez!
As you did in the screen, you need to use the lconfig
command to configure a device in a network scenario.
The vconfig
command is needed to add/remove interfaces to devices ran using the vstart
command, probably my answer above is a bit ambiguous.
Just to be sure, is the lconfig
commands in you example working? Is the problem only in the vstart
command?
Hi!
Sorry, I only posted the screenshot and I didn't explain the situation a little bit more (and I haven't pushed the changes in the lab's branch, now I did).
But this time I played around this a little bit more and what I didn't understand (until now) was that the katara lconfig -n <container> --add A
actually adds a new interface to the container "plugged" to the A
network, so in order to use it I had to configure it first (assigning a new IP address within that A
network, for example).
Sorry for the mistake. Now I know how to configure my lab, until the underlying bug gets fixed.
Thank you!
The current implementation of port forwarding in Kathará encounters an issue when the bridged interface is not the first one on a device. This error is related to a Docker Desktop issue (docker/for-mac#6978) that affects port forwarding functionality.
To address this issue, while waiting for an official Docker fix, we propose a possible workaround that involves starting the device with only the bridged interface initially and then dynamically connecting other interfaces using the
vconfig/lconfig
command.In the following you can find a quick example, which starts a device with the
apache2
service exposed on port8080
of the host:Now, you can attach a new interface using the
vconfig
command:In this way, the port forwarding works and you can attach other interfaces to the device.
