[dpdk-users] DPDK-app to 2 containers - shared-mem

[dpdk-users] DPDK-app to 2 containers - shared-mem

[Sara Gittlin]

Hi,
i need to  connect 2 containers to my DPDK-app , and to send the pkts to
both containers.
for a zero copy i need a shared mem between the DPDK-app and the 2
containers , and to put a ref-counter to free the mbuf when this counter is
zero.
can someone refer me to a similar setup/example ?
Thank you
-Sara

Hi Sara,

It is doable if your container app is implemented as secondary process. 
You can connect container apps via ring PMD by sharing hugepage between 
host and container.

I have tried to deploy my application on container environment. Some 
examples of Dockerfiles or docker commands are explained in my material 
here. I hope it will be some help.

You can check out OpenNetVM, which is a DPDK-based NFV framework that
supports running NF service chains that span multiple containers.
