Configure the dashboard service for a Kubernetes Cluster

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 files and integrate them into the local warehouse for unified management

# 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

2. Create Deployment and service based on the rc file

Iii. web Access Testing
You can access the web-ui interface by using the ip address and port of two node nodes, which is essentially implemented using iptables nat rules.




On the panel, you can view
Node, deployments, replica sets, replication controllers, pod, jobs, services, ingress, storage, secret, and other information are essentially queried by connecting to apiserver and displayed on the web-ui.
