kubernetes pod vs deployment

Hi,everybody, I came back, before the installation to flannel, the article has not been updated, even a lot of small partners to add QQ asked whether to continue to update,Here is the reason, I was in the deployment of 1.91node when there are a variety of problems, resulting in node startup Oh, master always do not see, the problem is probably1, Virtual machine time synchronization inconsistency problem, causing ETCD to create a resource is unsuccessf

Controller manager, as the Management control center within the cluster, is responsible for the resource management in the cluster, including node, Pod, namespace, and rated resources. For example, when an unexpected node outage occurs, Controller Manager will promptly discover and perform an automated fix.First, deploy k8s Controller ManagerMake sure Controller-manager-key.pem and Controller-manager.pem exist, and I've created the relevant private ke

Q: If the DHCP server hangs up after the deployment play, how do I handle not letting the deployed environment drop? A:DHCP can do hot preparation, has been deployed, we have made a static IP, so will not fall off the line Q: Why use pod to assign IP to a separate container?

Multiple pods can be hung behind a service, enabling high availability of services. The normal stateful service, compared with stateless services, has more requirements for state preservation.
