deploy pod kubernetes

This is a creation in Article, where the information may have evolved or changed. Kubernetes cluster has been set up, has been running very stable. Previous concerns have focused more on installation, configuration, and component debugging, and some of the minutiae has been overlooked. The settings for the time zone in the pod are one of them. I'm going to try to solve this problem today. First, the problem

"Editor's words" The Kubernetes Scheduler dispatches the pod to the work node according to a specific algorithm and strategy. By default, the Kubernetes scheduler can meet most of the requirements, such as scheduling pods to run on resource-rich nodes, or scheduling pod dispersal to different nodes to make cluster node

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can create a pod containing three container.

Recently started to study kubernetes, the operation of the container, the discovery has been in the containercreating state, sad a reminder, just started to encounter a bit of trouble, the following talk about how to find the problem and solve theTo run the container command:KUBECTL-F Create Redis.yamlKubectl Get pod RedisNAME Ready STATUS RestartsREDIS-MASTER-6JGSL 0/1 containercreating 0 12sAlways in cont

You need to remove the following pod, but you cannot delete it using the following command: KUBECTL delete pod kong-rc-2364486572-3hgpk Looking at this instance's information, we found that the container was running on kubernetes node, but now that node is down. So now that node is down, it's time to just remove node. After node deletion, the

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_RJA

Kubernetes ArchitectureThe overall architecture of the kubernetes is as follows:Master is the main control node, which runs Apiserver,scheduler,controller-manager and other components. Minion is the equivalent of a working node, which runs Kubelet,proxy,cadvisor and the most important Docker components. Here's how to actually deploy this cluster management tool.E

Deploy Kubernetes in Docker Kubernetes is an open-source container management framework of Google. It provides a series of functions such as host, cluster management, container deployment, high availability, and auto scaling of Docker containers; kubernetes's design goals include putting the container cluster in the desired state at any time. Therefore, a complet
