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 168.108.0.0/16

启动成功后，会有3个weave的容器运行中

# docker ps -a
c9ed14e97dfd        weaveworks/weave:2.0.4                 "/home/weave/weave..."   2 days ago          Up 2 days                                   weave

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 168.108.0.0/16

(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

[[email protected] /]# ping 168.108.192.0

(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-3.0.6.tar.gz
tar xzvf iperf-3.0.6.tar.gz
cd iperf-3.0.6
./configure
make
make install

在节点2上启动iperf服务

# iperf3 -s

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。

docker (centOS 7) 使用笔记5 - skydns

skydns被用于kubenets作为DNS服务.本次测试是单独使用skydns作为DNS服务器,且作为loadbalance使用. 前提:需要先安装配置etcd服务 (在前面的文章里,已经安装部署了etcd服务) 1. 下载安装 go get github.com/skynetservices/skydns cd ~/go/src/github.com/skynetservices/skydns go build -v 2. 启动 #etcd的client URL export ETCD_MA

如何使用 Weave 网络？- 每天5分钟玩转 Docker 容器技术（63）

weave 是 Weaveworks 开发的容器网络解决方案.weave 创建的虚拟网络可以将部署在多个主机上的容器连接起来.对容器来说,weave 就像一个巨大的以太网交换机,所有容器都被接入这个交换机,容器可以直接通信,无需 NAT 和端口映射.除此之外,weave 的 DNS 模块使容器可以通过 hostname 访问. 实验环境描述 weave 不依赖分布式数据库(例如 etcd 和 consul)交换网络信息,每个主机上只需运行 weave 组件就能建立起跨主机容器网络.我们会在 ho
