Kubernetes is a distributed cluster of Google's Docker based, with the following main components　　ETCD: High-availability storage sharing configuration and service discovery, used as a companion to flannel on Minion machines, to enable Docker running on each minion to have different IP segments The ultimate goal is to make the Docker Containner running on different minion have an IP address that is not the same as any other Containner (Docker Containn

Kubernetes client UAP development and client uapPreface Page navigation is a basic skill in the App. For a general App, you only need to perform simple Navigate + Back, A complex App may require a mixture of navigation modes to achieve the best user experience.SplashScreen startup Screen Let's start with the initial SplashScreen. If you make the boot screen into a Page, it will be displayed first when you start the screen, and then pretend to be busy

Batch JobsJobsOne job creates one or more pods and ensures that a specified number of Pods are successfully terminated. When all pods are completed successfully, the job will track the process. When the number of successful finishes reaches the specified number, the job itself ends.Reference Documentation:https://kubernetes.io/docs/user-guide/jobs/This article is from the Linux SA John blog, so be sure to keep this source http://john88wang.blog.51cto.

The pod is a container group, so let's create a pod now, just like Dockerfile.VI Nginx-pod.yaml (to pay great attention to the space, usually two spaces)Add to:Apiversion:v1Kind:podMetadataName:nginx1SpecContainers-NAME:NGINX1Image:docker.io/nginxPorts-containerport:9001Start podKubectl create-f Nginx-pod.yamlUse get Pods to view650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M01/88/89/wKioL1f7Tn_RJAOUAAAQwjCNxUA018.png "title=" 817cc777-d671-4aee-b74b-ca8300524af7.png "alt=" Wkiol1f7tn_r

Kubernetes 1.9 clusters use traefik to publish services This section describes how to use traefik to publish services in the kubernetes 1.5.2 cluster environment. Traefik is deployed in the daemonset mode. The http protocol is used to connect to the api-server, and rbac is not configured. This article describes how to deploy traefik in k8s 1.9 using deployment for service release. Before starting, You Need
