1、 删除默认的secret，用自签证书创建新的secret

kubectl delete secret kubernetes-dashboard-certs -n kubernetes-dashboard

kubectl create secret generic kubernetes-dashboard-certs \

--from-file=/opt/kubernetes/ssl/server-key.pem --from-file=/opt/kubernetes/ssl/server.pem -n kubernetes-dashboard

2、修改 dashboard.yaml 文件，在args下面增加证书两行

args:

# PLATFORM-SPECIFIC ARGS HERE

- --auto-generate-certificates

- --tls-key-file=server-key.pem

- --tls-cert-file=server.pem

kubectl apply -f dashboard.yaml
