Dedicated Interface Containers

This page describes the steps necessary to set up a perfSONAR Docker container that directly uses on of the host's physical interfaces.

This has been tested on 100 Gb/s interfaces and shows negligible loss of performance over bare metal.

Network

The container will be bound to physical interface eth1 and use IPv4 block 192.0.2.0/24 and IPv6 block 2001:db8::/32.

NOTE: Docker does not currently support IPv4 /31s but should in release 21.

docker network create -d macvlan \
                      --ipv6 \
                      --subnet=192.0.2.0/24 \
                      --gateway=192.0.2.1 \
                      --subnet=2001:db8::/32 \
                      --gateway=2001:db8::1 \
                      -o parent=eth1 \
                      host-eth1

Container

docker run -d --restart unless-stopped \
              --name=my-container \
              --hostname=my-container.example.net \
              --cpuset-cpus="12,13,14,15,16,17,36,37,38,39,40,41" \
              --memory=32g \
              --memory-swap=32g \
              --memory-swappiness=0 \
              --network=host-eth1 \
              --ip=192.0.2.1 \
              --ip6=2001:db8::2 \
              perfsonar/testpoint:v4.4.0
