generic kubectl to everyone. My advice is to isolate the team based on namespace and then use RBAC policies to limit the ability and access to only that namespace.After the permissions are controlled, you may become crazy, for example, to read, create, and delete pods based on pods only. But one of the things that needs to be done is to access only the administrator credentials, which can isolate who can manage the cluster and who can only deploy the app on the cluster.I am looking forward to a

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is

resource object can define any number of labels. Resource objects can be queried and filtered through the Labelselector (tag selector). Rc:replication Controller declares that the number of copies of a pod meets an expected value at any time. The definition includes the following: (1) Number of expected copies of pod (replicas) (2) Label Selector used to filter the target pod (3) When the number of pod re

Tags: composition instance provider application Application class version style implementationThe lifespan of kubernetes pods is limited and they are not resurrected, so although each pod has its own IP address, these IP addresses are unreliable and disappear as the pod dies. This poses a problem, if some of the pod's collections (called backends) are other pods of the cluster (called frontends), how do these frontends find and always know which backe
Externalname: Forwards the service through the DNS CNAME record to the specified domain name (set by Spec.externlname). Requires a Kube-dns version above 1.7. Alternatively, you can add existing services to the Kubernetes cluster as a service, simply by not specifying the label selector when you create service, but by manually adding endpoint to it after service creation.The service solves the pr

pod contains the container, the pod ends. Kubernetes designed a unique network configuration for pod, including assigning an IP address to each pod, using the pod name as the host name for communication between containers, and so on. 3. Service In the Kubernetes world, although each pod is assigned a separate IP address, the IP address disappears as the pod is destroyed, which raises the question of how to
