对Kubernetes 集群中的应用,Kubernetes 提供了简单的 Endpoints API,只要 Service 中的一组 Pod 发生变更,应用程序就会被更新。 对非 Kubernetes 集群中的应用,Kubernetes 提供了基于 VIP 的网桥的方式访问 Service,再由 Service 重定向到 backend Pod。 1.3 三种代理模式 userspace 代理模式(K8S 1.1之前版本) iptable...
A Kubernetes label allows you to logically group Kubernetes objects. These labels enable the system to query the cluster for objects that match a label with a specific name. The structure of a manifest file The structure of manifest files differs depending on the type of resource that you creat...

Step 3: Create Service Manifest in Kubernetes In this step, we create a file to start a regular service in Kubernetes. So, we run the command to create a manifest for regular service, which is: > nano regsev. yaml Run the command in the terminal and press enter. When the command is...
To deploy the application, you use a manifest file to create all the objects required to run the AKS Store application. A Kubernetes manifest file defines a cluster's desired state, such as which container images to run. The manifest includes the following Kubernetes deployments and service...
在集群管理方面,Kubernetes将集群中的机器划分为一个Master节点和一群工作节点(Node)。 Master节点上运行着集群管理相关的一组进程kube-apiserver、kube-controller-manager和kube-scheduler,这些进程实现了整个集群的资源管理、Pod调度、弹性伸缩、安全控制、系统监控和纠错等管理功能,并且都是全自动完成的。
