Rancher is an open-source full-stack enterprise container management platform, the user in the rancher visual interface in a single click to complete all the container infrastructure (network, storage, load balancing, etc.) docking and deployment, to ensure that the container on any infrastructure (public and private cloud, virtual machine, The physical machine, etc.) runs seamlessly. All the work of using containers in a production environment can be done with simple, intuitive operation.?start

Kubernetes cluster configuration notes
This article describes how to configure a Kubernetes cluster. A kubernetes cluster consists of a master node and a slave node.
Run the following services on the Master node:Etcd (the etcd service can also be run independently, not necessarily on the Master node)Kube-apiserverKube-controller-managerKube-schedulerKubeletKube-p

Kubecfg sends a specific request, such as creating a pod, to the Kubernetes Client.
Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network
-speed storage to store a large number of fragmented files. What the user needs to do is submit the resource request to the cloud platform and then fetch and consume the storage resource without worrying about which disk of the storage server The underlying store is from. to meet the storage needs of container users in the cloud environment. Kubernetes provides the concept of persistent volumes (PERSISTENTVOLUME,PV) and persistent volume requests (PE

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 detailOverviewThe Pods in

containers, making deployment and management more flexible. A pod can contain a container or multiple related containers. 2) Replication ControllerThe Replication Controller manages a copy of the pod to ensure that a specified number of pod copies exist in the cluster. If the number of replicas in the cluster is greater than the specified number, the number of extra containers that are outside the specified number is stopped, and conversely, containers with fewer than a specified
