The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is to ensure service ability and service quality
necessary to manage the image, do not need a service like glance?
Where is the image stored, does it require a service for object storage, similar to Swift?
Kubernetes itself no matter the network, need to through the plug-in, Network and SDN who to manage?
The kubernetes itself, regardless of the storage, needs to be done via plug-ins, and most of the storage options are done via Ceph.

in Audit.go, mainly deals with the user information of the request. The source IP, user name, user action and namespace of request requests are then credited to the relevant audit log.
The Withimpersonation () function, defined in Impersonation.go, primarily handles user impersonation by trying to modify the way the requested user (such as sudo) works.
The Withauthorization () function in Authorization.go defines the user right in the primary request for authentication, and if the validatio

The node nodes of Kubernetes are composed of Kubelet, Kube-proxy, flannel, dockerd four components, this paper mainly analyzes the functions and principles of kube-proxy components. Pod is the smallest unit of resource allocation in kubernetes and the smallest entity to perform tasks.
Each pod has a separate IP on the flannel overlay network. Pod Communication in node nodes is impleme

The cause of garbled characters is that the module encoding is different when the website is to be integrated.Like my blog, this problem occurs during integration, because the blog is Utf-8,Recently, many netizens have been asking for this question. I have tried many methods.Th

implementation of each Java EE application is difficult to leave behind the support of the DAO component. Spring provides a number of tool classes for implementing DAO components, and DAO components of the system can be accomplished by inheriting these tool classes, making it easier to implement DAO components.Spring provides a series of abstract classes that will be used as the parent class of the DAO implementation class in the application. By inheriting these abstract classes, spring simplif
Learning XML Today encountered this problem, Internet access to data analysis, the main reason for this problem is that the XML file is declared in the XML file itself when the encoding is inconsistent. For example, your statement is"1.0" encoding="UTF-8"?> However, it is saved in ANSI format, although it does not appear garbled, but the XML parser is unresolved.The workaround is to reset the encoding and declaration of the XML file when it is saved.C
