Kubernetes Network Model A fundamental principle of the Kubernetes network model design is that each pod has a separate IP address, and that all pods are in a flat network space that can be directly connected. So whether or not they run in the same node (host), they are required to be accessed directly from each other's IP. The reason for this principle is that the user does not need to consider ho

One. Container:1. A container is a way to run one or a set of processes, isolating these processes from other processes on the host2. Containers are similar to virtual machines, but different from virtual machinesContainer virtual machineKernel calls the host's kernel per virtual machine oneStart speed seconds-level minuteResources use only the processes in the container occupy the entire virtual machineTwo. What is Kubernets?1. is a container organizer, or container manager:Not only manages con

Heapster is a container cluster monitoring and performance analysis tool that naturally supports kubernetes and CoreOS.Kubernetes has a well-known surveillance agent-cadvisor. The cadvisor is run on each kubernetes node, and it collects monitoring data (cpu,memory,filesystem,network,uptime) for both native and container.In the newer version, K8S has integrated the Cadvisor functionality into the Kubelet com

The previous article describes the use of Traefik for service publishing in Kubernetes 1.5.2 cluster environments. Traefik is deployed in Daemonset mode, and the connection Api-server is the HTTP protocol, and RBAC is not configured. This article describes the deployment of Traefik for service publishing in the K8s 1.9 release using the deployment method.Before you begin, you need to know what RBAC is. RBAC (role-based access control) using the Rbac.a

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant increase in the core API resource types until
