Yes. Try mapping the dpdk metadata directory (/var/run/dpdk) into both containers from the host. You should be able to do the normal dual process methods.

Hello

I wonder if it is possible to use the DPDK multi-process feature in Docker containers?

That is, can a DPDK application execute in a Docker container and share its
DPDK memory with another DPDK application executing in another Docker container
using the DPDK multi-process feature?

For example if the DPDK example mp_server executes in one Docker container:
<build_dir>/examples/dpdk-mp_server -l 1-2 -n 4 -- -p 3 -n 2

and the DPDK example mp_client executes in another Docker container:
<build_dir>/examples/dpdk-mp_client -l 3 -n 4 --proc-type=auto -- -n 0

Is this possible to implement?

Thanks
