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.

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 addition, OPS will want this OpenStack lifecycle management system to span bare metal, IaaS, and even PAAs.What Atomic, Docker, Kubernetes bringIf you have an OpenStack service lifecycle management scenario, the following benefits can be created: Isolated, lightweight, portable, detachable The service relationship of the running state is easy to describe Easy to run, easy to update Manage service life

Article from: Listen to the Cloud blogAs our business continues to grow, our number of applications has exploded. With the growth of application explosion, the difficulty of management is increased. How to quickly complete the expansion while the business explosion is growing is a big challenge. The advent of Docker happened to solve our problem. With Docker, we can quickly complete the expansion and contraction, and the configuration is uniform and error-prone.In the Docker cluster management s

Kubernetes about the service exposure is mainly through the Nodeport way, through the binding minion host of a port, then the pod request forwarding and load balancing, but this way the defect is The service may have many, if each is bound to a node host port, the host needs to open the perimeter of a heap of ports to make services calls, management confusion Cannot apply firewall rules required by many companies The ideal way is thr

OverviewKubernetes is a powerful container orchestration tool that enables users to reliably deploy and run containerized applications on a scalable system. Within the container area, k8s has undoubtedly become a community standard for container orchestration and management, and even Docker has announced support for K8s. The fighting in the field of container orchestration has been turned around, and the dust settles, and k8s has been unanimously endorsed by the players including Google, Huawei,
