kubernetes pod example

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

Kubernetes How to manage pods using Replicationcontroller, Replica Set, deployment53746273The pod is literally a pod, and we can think of the container as a bean in a pod, and one or more closely related beans wrapped together as pods (a pod). In the k8s we do not directly m

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

1. Emptydir (Local data volume)The Emptydir type of volume is created when the pod is dispatched to a host, and the container within the same pod can read and write to the same file in the Emptydir. Once the pod has left the host, the data in the EMPTYDIRR will be permanently deleted. So the current Emptydir type of volume is primarily used as a temporary space,
