Kubernetes, abbreviation K8s are to replace abridging made of 8 characters " ubernete " with 8.It is an open source,
For managing the application of the containerization in cloud platform in multiple main frames, the target of Kubernetes is to allow the application of deployment container
Simple and efficient, Kubernetes is provided using deployment, planning, a kind of mechanism for updating and safeguarding.
Traditional application deployment way is to install application by plug-in unit or script.Disadvantage of this is that the fortune of application
Row, configuration, management, all life cycles will bind with current operation system, do so the upgrading for being unfavorable for applying and update/return
The operation such as rolling, naturally it is also possible to certain functions are realized by way of creating virtual machine, but virtual machine is very heavy, and unfavorable
In portability.
New mode is realized by deployment container mode, is mutually isolated between each container, and each container has oneself
File system, process will not influence each other between container, can distinguish computing resource.Relative to virtual machine, container energy rapid deployment,
Since container and bottom facilities, machine file system decouple, so it can be carried out between different clouds, different editions operating system
Migration.
Container takes up less resources, disposes fastly, and each application can be packaged into a container mirror image, each application and container
Between in a pair a relationship also container is made to have greater advantages, can be in the stage of build or release, for application wound using container
Container mirror image is built, because each application does not need to combine with remaining application stack, also not dependent on production environment foundation structure,
This makes from researching and developing to testing, produces and can provide consistent environment.Similarly, container than virtual machine light weight, more " transparent ", this is more just
In monitoring and management.
As shown in Figure 3 and Figure 4, the container Scheduling Framework system of the present embodiment further includes virtual DNS component, described virtual
Creation of the DNS component for container node in monitoring of containers clustered node.The virtual DNS component is also used in the memory unit

In second message of routing iinformation, the second message is forwarded to target physical master according to routing iinformation by the network extension element
Machine;Network process on the target physical host obtains the first message for being responsible for the second message of decoding, and first is reported
Text is forwarded at the bridge at target physical host.First message is TCP message.Second message is UDP message.
IP caused by virtual DNS component solution dynamic creation container is unpredictable, is responsible for monitoring the wound of container in cluster
Build situation, virtual DNS, which is responsible for searching host name in ETCD storage and correspond to IP and distributes to container, to be used, and passes through network expanded set
Part realize container across host communication, the TCP message of container bridge is packaged in the UDP message with routing iinformation, net
Message is forwarded to target physical host by routing iinformation by network extension element, and the network process on target physical host is responsible for solution
Packet.TCP message is forwarded on the container bridge of the machine, to be realized in the case where not influencing container legacy network mechanism
Container across host communication.DNS (domain name system), provides domain name resolution service, solves the IP for being difficult to remember
Address problem, by more human nature it is readable remember can identify in a manner of map corresponding IP address.Domain name mapping is that domain name is directed toward net
Stage space IP allows people that a kind of service of website is accessed by the domain name registered with can be convenient.IP address is network subscript
Know the numeric address of website, remember for convenience, IP address is replaced to identify site address using domain name.Domain name mapping is exactly domain
Name arrives the conversion process of IP address.The parsing work of domain name is completed by DNS component.
Domain name mapping also makes domain name be directed toward, server setting, domain name configures and reversely IP registration etc..Say to obtain simple point
It is exactly by domain name mapping easy to remember into IP, it is then domain name mapping is existed to an IP address that service is completed by dns server
A subdirectory and domain name are bound on the host of this IP address.Dynamic-dns (English: Dynamic DNS, abbreviation DDNS) are domains
One of name system (DNS) automatically updates the technology of name server (Name server) content.According to the domain name of internet
Rule is concluded, domain name must follow fixed IP address.But dynamic DNS system provides a fixed title clothes for dynamic domain
Business device (Name server) enables external user to connect the network address of dynamic subscriber through immediate updating.
