kubernetes container

Brief introductionKubernetes is an open source, containerized application for managing multiple hosts on a cloud platform, with the goal of making deploying containerized applications simple and efficient, Kuernetes provides a mechanism for application deployment, planning, updating, and maintenance.In Kubernetes, all containers are run in pods, and one pod can host one or more related containers. Each pod system created by the user automatically choo

The following is the version of the component used in the test: Kubernetes master:v1.9.0 node:v1.9.0 Calico v2.5.0 Calico-policy-controller quay.io/calico/kube-policy-controller:v0.7.0 Run Configuration Calico side,

first introduce what k8s is: (Quote from k8s Chinese community)Kubernetes is a container cluster management system, it is an open source platform, can realize the automatic deployment of container cluster, auto-scaling capacity, maintenance and other functions. Kubernetes you can: Quick Deploy app

Official Document: HTTPS://WWW.KUBERNETES.ORG.CN/DOC-11The Kubernetes cluster contains the node agent Kubelet and master components (APIs, scheduler, etc), all based on a distributed storage system. The following diagram is an architectural diagram of the kubernetes.Kubernetes nodeIn this system architecture diagram, we divide the service into services running on the work nodes and the services that make up the cluster-level dashboard.The

Kubernetes is Google 's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The pur

Summary: Kubernetes is Google open source container cluster management system, built on Docker, for containerized applications to provide resource scheduling, deployment operations, service discovery, capacity expansion and other functions. Pods are the smallest deployment units that are created, dispatched, and managed, and this article describes the communication and scheduling between these pods in detai

This is a creation in Article, where the information may have evolved or changed. K8s Offline installation package Three-step installation, simple to unbelievable Kubeadm Source Code Analysis To say the truth, Kubeadm code is sincere, the quality is not very high. A few key points to first talk about some of the core things Kubeadm did: Kubeadm Generate certificate in/etc/kubernetes/pki directory Kubeadm generate a static pod Yaml configurati

directly, and then execute the Replace command.Note: The name cannot be updated. In addition, if the label is updated, the original tag's pod will be disconnected from the RC after the label is updated, and RC with the new label will create a new pod with the specified number of copies, but the original pod will not be deleted by default. So at this point, if you use Get PO will find the number of pods doubled, further check will find that the original pod has not been the new RC control, here
