docker (centOS 7) 使用笔记5 - weave网络
weave官网 https://www.weave.works
1. 下载安装
sudo curl -L git.io/weave -o /usr/local/bin/weave
sudo chmod a+x /usr/local/bin/weave
2. 部署weave网络
(1) 在第一台机器上运行，如果使用默认的 10.0.*.* 网段则如下
weave launch
本次测试使用自定义的网段，所以启动指令有所不同：
weave launch --ipalloc-range 168.108.0.0/
启动成功后，会有3个weave的容器运行中
# docker ps -a
c9ed14e97dfd weaveworks/weave:2.0. "/home/weave/weave..." days ago Up days weave
7db070b5f54e weaveworks/weaveexec:2.0. "/bin/false" days ago Created weavevolumes-2.0.
b6d603c8c7a8 weaveworks/weavedb "data-only" days ago Created weavedb
可看到增加了虚拟网卡 weave

(2) 其他的节点加入加入上面已经创建的weave网络
weave launch 10.28.148.61 --ipalloc-range 168.108.0.0/
(3) 创建网络成功的话，在每个节点上都可以用docker命令查看到weave网络
# docker network ls
NETWORK ID NAME DRIVER SCOPE
7c19813ffbff bridge bridge local
a7a2188380ba docker_gwbridge bridge local
7f97ac1cfe6e host host local
z08xcdlswkbk ingress overlay swarm
dfa68b3918b3 none null local
42f695c8c061 weave weavemesh local
3. docker启动测试
(1) 启动相当简单，仅需正常的docker命令中指定network为weave就行了
docker run -ti --network weave mytest
(2) 在2个节点上启动容器
在容器内部ifconfig可以看到容器使用的是weave的子网段，2个节点分别是168.108.0.1和168.108.192.0

在容器里可以互相ping通

(3) 网速测试：
本次测试的环境是阿里云上的ECS，内网带宽为 1Gbits。
先安装iperf3(网速测试工具)
curl "http://downloads.es.net/pub/iperf/iperf-3.0.6.tar.gz" -o iperf-3.0..tar.gz
tar xzvf iperf-3.0..tar.gz
cd iperf-3.0.
./configure
make
make install
在节点2上启动iperf服务
# iperf3 -s
-----------------------------------------------------------
Server listening on
-----------------------------------------------------------
在节点1上启动网速测试
# iperf3 -c 168.108.192.0

测试下来平均网速：发送速度 859 Mbits/sec ，收取速度 856 Mbits/sec。网速还是让人比较满意的。
