This article to share with you the steps of kubernetes deployment of DashBoard, I believe that most people have not learned this skill, in order to let you learn, to sum up the following content about kubernetes deployment of DashBoard.

All of the following are done when a single master cluster has completed its deployment.

All servers ensure that the firewall is always closed and the core function selinux is turned off.

Establish a dashboard working directory

# operate on master [root@master ~] # cd / k8s/# will upload the page file to this folder [root@master k8s] # mkdir dashboard

"dashboard-rbac" license to connect to APIserver

"dashboard-secret" for encryption configuration

"dashboard-configmap" dashboard profile

"dashboard-controller" application configuration

"dashboard-service" is used to publish applications

The above four YAML files are downloaded from GITHUB at https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/dashboard

The order of generating related POD# cannot be changed! Remember! Remember! [root@master dashboard] # kubectl create-f dashboard-rbac.yaml [root@master dashboard] # kubectl create-f dashboard-secret.yaml [root@master dashboard] # kubectl create-f dashboard-configmap.yaml [root@master dashboard] # kubectl create-f dashboard-controller.yaml [root@master dashboard] # kubectl create-f dashboard-service.yaml put POD into the specified namespace [root@master dashboard] # kubectl get pods-n kube-systemNAME READY STATUS RESTARTS AGEkubernetes-dashboard-65f974f565-d2wgw 1 move 1 Running 2 90s# View details [root@master dashboard] # kubectl get pods Svc-n kube-systemNAME READY STATUS RESTARTS AGEpod/kubernetes-dashboard-65f974f565-d2wgw 1 Running 1 116sNAME TYPE CLUSTER-IP EXTERNAL-IP PORT (S) AGEservice/kubernetes-dashboard NodePort 10.0.0.109 443:30001/TCP 112s at this time You can access port 30001 of a node node in the browser

The root cause of this problem is the lack of certificates, and some browsers block insecure access

Write an execution script to self-sign the certificate

[root@master01 dashboard] # bash dashboard.sh / root/k8s/apiserver/## script is written manually #! / bin/bash#DashBoard Certificate # cat > dashboard-csr.json
