Hello! Has anyone here used Containernet with DPDK before? Our use-case is evaluating DPDK-based applications under different network conditions (e.g., lossy links).
I've watched this talk https://www.youtube.com/watch?v=KPshkuEPOOU, and I've done pretty extensive research into running DPDK applications in containers for intra-host container networking. (+ thank you to all those who responded to my previous question on this forum!) My understanding is that there are two approaches to DPDK + container networking: - Aggregation: Using VirtIo-User (containers) and vhost-user (backend) which offers a software PMD. This also needs to be connected to a virtual switching infrastructure on the host. - Slicing: Using SR-IOV or similar to give containers direct access to devices. I'm not sure how to reconcile these options with Containernet, both conceptually and in practice. Conceptually: - Does Containernet's OVS <https://github.com/containernet/containernet/blob/8e0aabef8f23def3961b30897dd486191d9bd693/util/install.sh#L406>/switching provide the appropriate infrastructure for the aggregation option? - Is Containernet even compatible with the VF/slicing option? Can I just build a Containernet node from a DPDK-compatible Dockerfile, set it up with the correct (sliced) PCI addresses, and then connect it to Containernet's emulated network? Would I have to configure anything on the emulated network to make this work? In practice: this seems like a really common use-case (DPDK is specifically mentioned in the original Containernet talk!). However, I can't find any clear guides or images for this, in the Containernet repo or otherwise. Thank you in advance! Thea
