Configure the dashboard service for a Kubernetes Cluster This article describes how to create and use kube-ui (also called dashboard) based on the previous article. This is essentially an api interface for connecting webui to the master. It obtains information about the k8s cluster through the api and then displays it on the web, which is more friendly to users, it is not very useful. 1. Download image file

in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flann

microservices are integrated with Envoy sidecar, and all traffic to and from the integrated service is hijacked by Sidecar, so that the required hooks are prepared for external control, and then the Istio control plane can be used to provide service routing for the application,Functions such as telemetry data collection and policy enforcement.Next, according to the Istio environment, follow the instructions below to complete the deployment of the application. First verify that the

create a corresponding RBD block for kubernetes storage. Before you create a block device, you need to create a storage pool, and Ceph provides a default storage pool called RBD. We then create a kube store dedicated to storing the block devices used by kubernetes, and subsequent operations are performed on Client-node:Ceph OSD Pool Create

Heapster is a container cluster monitoring and performance analysis tool that naturally supports kubernetes and CoreOS.Kubernetes has a well-known surveillance agent-cadvisor. The cadvisor is run on each kubernetes node, and it collects monitoring data (cpu,memory,filesystem,network,uptime) for both native and container.In the newer version, K8S has integrated the Cadvisor functionality into the Kubelet com
