Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

Today brings you a tutorial on creating a kubernetes cluster quickly with Docker. This tutorial is based on my previous article "10-minute deployment of kubernetes cluster," updated, condensed. This tutorial has been verified by me many times, and it has some guiding sign
what is kubernetes.
Kubernetes is a new, container-based distributed architecture leading solution. is an open source version of Google's internal cluster management system, Borg. It was not known until April 2015, when the papers were published. Kubernetes is an open platform for development. is not limited to any one language and does not qualify any programm
1.1. What is Kubernetes?A new approach to distributed architecture based on container technologyA complete distributed system support platformKubernetes is an open source project launched by the Google team, which aims to manage containers across multiple hosts, provide basic deployment, maintenance, and use scaling, primarily to implement the language as the Go language.1.2. Basic ConceptsNode: In Kubernetes
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

Brief Description:Using the Rke tool, on the 192.168.3.161 machine, create a kubernetes cluster with two nodes (192.168.3.162 and 192.168.3.163). Rke automatically creates KUBE_CONFIG_CLUSTER.YML configuration files in the/home/user directory.On another server (192.168.3.160), run the Rancher Server 2.0 container. After running, use the https://192.168.3.160 address to access Rancher Server 2.0 preview. (Note: No longer the previous 8080 port)In the R
