But because of its leadership in the field of service orchestration and its hig

. Applications should give full play to the potential of kubernetes.The kubernetes application is communicating using the service. There are different types of services in Kubernetes, and they are treated as load balancers. The service name defined is your endpoint http://service_name:port.If you are using a stateful application, you will want to use headless services to access specific pods.

ensure they each have a reasonable memory on- cgroups line All you need to do is write a call Kubernetes API to the program (Controller "controllers") Another cool Kubernetes API thing about it is that you don't have to be limited to Kubernetes some of the management methods you provide, and you can write your own program calls to implement your own customiz

seem to work ). The Kubernetes cluster depends on two third-party components: etcd and docker. The former provides status storage, and the two are used to manage containers. Clusters can also use distributed storage to provide storage space for containers. Displays the components of the current system: Kubernetes proxy nodes Kubelet and Kube-proxy run on the proxy node. They listen to Service node informa

The Kubernetes network model is made up of four parts from inside to outside: The network where the pod interior container resides The network where the pod resides Network for communication between pod and service Network of communication between outside and service It is recommended that you understand the network model of Docker before reading this article.

set of endpoint that communicates with each other, which is closer to the network definition in neutron.In CNM, the Docker engine invokes the network implementation via the HTTP REST API to configure the network for the container. These API interfaces cover more than 10 interfaces such as network management, container management, creating endpoint, and so on. The CNM model also implies additional constraints such as the service mechanism, DNS mechanism, and so on, which are included with Docker

1. Basic architecture1.1 MasterThe master node consists mainly of four modules: Apiserver, Scheduler, controller manager, ETCD.　　　　apiserver. Apiserver is responsible for providing restful Kubernetes API service, it is the unified entrance of the System Management Directive, any operation that increases and deletions the resources should be handed over to apiserver processing and then submitted to ETCD. As shown in the architecture diagram, KUBECTL (t

: Applications are divided into small stand-alone slices that can be deployed and managed dynamically without the need to run a fat stack on a large, single purpose host. Resource Isolation : Predictable program performance. Maximize Resource Utilization : High performance, high density. Why do I need kubernetes, what does it do?

What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

largely provided by the Kubernetes API-it is used as an internal component of expansion and a container running on Kubernetes. Because Kubernetes is a system composed of many components, it is still difficult to install and deploy Kubernetes, and Kubernetes is developed by

The biggest challenge for the container cloud platform in terms of ease of use is the troubleshooting, the container cloud is ultimately delivered to the developer, and they don't know about kubernetes, which makes troubleshooting a challenging process. Now we just want
