Kubernetes Cluster Configuration Dashboard Service

This article will introduce the creation and use of Kube-ui (also called dashboard) on the basis of the previous article. This thing is essentially the WebUI connection Master API interface, through the API to obtain information about the k8s cluster, and then on the web display, for the user is more friendly, the actual use is not very large.

One, download the image file and incorporate the unified management of the local warehouse

# docker pull docker.io/mritd/kubernetes-dashboard-amd64# docker tag docker.io/mritd/kubernetes-dashboard-amd64  registry.fjhb.cn/kubernetes-dashboard-amd64# docker push registry.fjhb.cn/kubernetes-dashboard-amd64

Second, create deployment and service according to RC file

# kubectl create -f kube-ui-rc.yaml # kubectl get svc# kubectl get pod

Third, Web Access testing
IP plus ports with two node nodes can be accessed to the Web-ui interface, which is essentially implemented using the iptables NAT rule




You can see it in the panel.
Node, deployments, replica sets, replication controllers, pod, jobs, services, ingress, storage, secret and other information, In essence, queries are made by connecting Apiserver and displayed on Web-ui.
