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

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 unsuccessful2, node nodes can not automatically create

Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

This tutorial is based on my previous article "10-minute deployment of kubernetes cluster," updated, condensed. This tutorial has been verified by me many times, and it has some guiding sign

what is kubernetes. Kubernetes is a new, container-based distributed architecture leading solution. is an open source version of Google's internal cluster management system, Borg. It was not known until April 2015, when the papers were published. Kubernetes is an open platform for development. is not limited to any one language and does not qualify any programm

Brief Description:Using the Rke tool, on the 192.168.3.161 machine, create a kubernetes cluster with two nodes (192.168.3.162 and 192.168.3.163). Rke automatically creates KUBE_CONFIG_CLUSTER.YML configuration files in the/home/user directory.On another server (192.168.3.160), run the Rancher Server 2.0 container. After running, use the https://192.168.3.160 address to access Rancher Server 2.0 preview. (Note: No longer the previous 8080 port)In the R
