Docker+OVS-DPDK

创建容器

创建Dockerfile：

FROM ubuntu:18.04
WORKDIR /usr/local/f-stack
COPY . /usr/local/f-stack
RUN apt-get update && apt-get install -y libnuma-dev libssl-dev vim libpcap-dev
ENV PATH "$PATH:/usr/local/f-stack/dpdk/build/app/"

创建镜像：

docker build -t f-stack .

运行容器：

docker run -ti --privileged --name f-stack \
-v /mnt/huge:/mnt/huge \
-v /usr/local/var/run/openvswitch:/var/run/openvswitch \
-v /usr/local/lib:/usr/local/lib\
-v /usr/local/include \
f-stack

docker exec -it <ID> bash

链接动态库：

echo "/usr/local/lib/x86_64-linux-gnu" >> /etc/ld.so.conf && ldconfig

测试ovs-dpdk和docker

第一次测试

先在第一个容器中运行pktgen，在第1、2端口上发包和收包：

pktgen-21.02.0/build/app/pktgen -c 0x6 --master-lcore 1 -n 1 --socket-mem 1024 --no-pci --vdev 'net_virtio_user1,mac=00:00:00:00:00:01,path=/var/run/openvswitch/vhost-user1' --vdev 'net_virtio_user2,mac=00:00:00:00:00:02,path=/var/run/openvswitch/vhost-user2' -- -T -P -m "2.0，2.1"

在第二个容器中运行testpmd，进行包转发4<->3：

./dpdk/build/app/dpdk-testpmd -c 0xa --master-lcore 1 -n 1 --socket-mem 1024 --no-pci --vdev 'net_virtio_user3,mac=00:00:00:00:00:03,path=/var/run/openvswitch/vhost-user3' --vdev 'net_virtio_user4,mac=00:00:00:00:00:04,path=/var/run/openvswitch/vhost-user4'  --  -i

设置pktgen中的发包数量：

set 0 count 10000000
set 1 count 10000000
str

结果：

Total Rx Pkts       :              9998848              9998816                     
      Tx Pkts       :             10000000             10000000

丢包率为0.01%

第二次测试：测试pmd线程公用lcpu

结果：

Total Rx Pkts       :               113152               113184 
      Tx Pkts       :             10000000             10000000

丢包率为99%
