准备工作
- Ubuntu 16.04
- 已经编译好的docker-sonic-vs.gz文件

nonames@Ubuntu16:~$ pip list | grep att
attrs 19.1.0
nonames@Ubuntu16:~$
#如果不符，重新安装attrs==19.1.0
nonames@Ubuntu16:~$ sudo pip install attrs==19.1.0
- 安装必要的docker工具
nonames@Ubuntu16:~$ sudo apt-get remove docker-engine docker-ce docker.io
nonames@Ubuntu16:~$ sudo apt-get update
nonames@Ubuntu16:~$ sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common

#!/bin/bash
SWNAME=$1
pid=$(docker inspect --format '{{.State.Pid}}' $SWNAME)
echo Seting up servers
SERVERS=31
for srv in `seq 0 $SERVERS`; do
SRV="$SWNAME-srv$srv"
NSS="ip netns exec $SRV"
ip netns add $SRV
$NSS ip addr add 127.0.0.1/8 dev lo
$NSS ip addr add ::1/128 dev lo
$NSS ip link set dev lo up
# add virtual link between neighbor and the virtual switch docker
IF="eth$((srv+1))"
ip link add ${SRV}eth0 type veth peer name $IF
ip link set ${SRV}eth0 netns $SRV
ip link set $IF netns ${pid}
echo "Bring ${SRV}eth0 up"
$NSS ip link set dev ${SRV}eth0 name eth0
$NSS ip link set dev eth0 up
echo "Bring $IF up in the virtual switch docker"
nsenter -t $pid -n ip link set dev $IF up
done
