I won’t have the answers, but some questions to help clarify…

Q1. Are these all kata-container VMs

Q2. Are you using some standard container networking infra, like CNI, to link them together?

Afaik, kata should ‘just work’ if sat under a CNI setup.

Kata has a number of ways it can discover/config/integrate with the networking passed in from the higher levels – iirc, we default to using ‘tcfilter’ at the moment. Have a look in the config file for some more info.
https://github.com/kata-containers/runtime/blob/master/cli/config/configuration-qemu.toml.in#L378

bottom line is I think, if the higher level orchestration has set up the networking correctly as it would for say ‘runc’, then kata should pick that up and translate/re-configure it into the VM and host side so it works ‘seamlessly’.

Subject: [kata-dev] Networking between containers in qemu processes

Hi,
I'm looking for information on how to set up communication between containers running within virtual machines.  On a host, there are multiple VMs with containers and set up networking between the containers in different VMs.

Thanks,
Al
