mesos-dns 与 CNI 集成

Mesos-DNS 部署

Mesos-dns是 mesos 服务发现工具，能查找app的Ip，端口号以及master，leader等信息。在Apache Mesos 集群中,允许应用程序和服务通过域名系统(DNS)来相互定位。Mesos-DNS 的特点是轻量、无状态,易于部署和维护。Mesos-DNS 将每个集群中正在运行的应用程序的域名转换成IP 地址和端口号。这使得任何链接到集群中运行的服务都可以通过DNS 进行查找。 Mesos-DNS是简单和无状态的，它不需要一致性机制，持久存储或日志复制，因为应用所需的心跳，健康监控或生命周期管理等功能都已经由Master、Agent和框架所提供。Mesos-DNS可以通过使用像Marathon这样的框架来实现容错，可以监控应用程序运行状况并在应用出现故障时重新启动它。Mesos-DNS因故障重新启动时，无需进一步协调它会从Master节点检索最新的应用状态，然后处理DNS请求。可以通过增加Master节点，即可提高可用性并为大规模集群中的DNS请求提供负载均衡。

Mesos-DNS 安装

Mesos-DNS 可以装在Mesos集群的任意一台机器上，或者是在同一网络的一台专用机器上。为了实现HA，可以在多个master上分别部署mesos-dns 实例。

wget https://github.com/mesosphere/mesos-dns/releases/download/v0.6.0/mesos-dns-v0.6.0-linux-amd64
sudo mv mesos-dns-v0.6.0-linux-amd64 /usr/local/bin/

ss-redir 透明代理.md

##ss-redir 的 iptables 配置(透明代理)

透明代理指对客户端透明，客户端不需要进行任何设置就使用了网管设置的代理规则

创建 /etc/ss-redir.json 本地监听 7777 运行ss-redir -v -c /etc/ss-redir.json

iptables -t nat -N SHADOWSOCKS
# 在 nat 表中创建新链
iptables -t nat -A SHADOWSOCKS -p tcp --dport 23596 -j RETURN
# 23596 是 ss 代理服务器的端口，即远程 shadowsocks 服务器提供服务的端口，如果你有多个 ip 可用,但端口一致，就设置这个
