Running a High Availability Service on CoreOS using Docker, Fleet, Flannel, Etcd, Confd & Nginx

• View the diagram of what's going on: https://drive.google.com/file/d/0B74l6vUHf9HrMzNrYUlyMm40RWs/view?usp=sharing

Tools used:

• coreos: server machine clustering via a shared cloud-config.yml
• etcd: key value store for service registration and discovery
• fleet: scheduling/failover of docker containers across coreos cluster
• flannel: Gives each docker container a unique ip that allows you to access the internal port (i.e. port 80 not 32679)
• confd: watch etcd for nodes arriving/leaving - template nginx configuration files / reload nginx on change

Linux NetFilter, IP Tables and Conntrack Diagrams

IPTABLES TABLES and CHAINS

IPTables has the following 4 built-in tables.

1) Filter Table

Filter is default table for iptables. So, if you don’t define you own table, you’ll be using filter table. Iptables’s filter table has the following built-in chains.

对于图片相似度比较有很多方法，我们这以RGB直方图为例。
我们以一种规则，使得每个图片生成一组描述的特征向量。
opencv的直方图比较函数我们可以巧妙的利用，其有若干比较规则，但只支持直方图的数据结构，我们可以将特征向量拟合成直方图的数据结构，然后使用其的相似度比较函数。
具体的数学计算方法有兴趣的可以看opencv的官方教程，这里我们期望生成百分比形式的相似度参数，所以使用CV_COMP_CORREL
 
以下是代码，以python编写
