1.创建自签证书
1
|
openssl req -newkey rsa:2048 -nodes -keyout tls.key -x509 -days 3650 -out tls.crt
|
2.创建secret

|
如果服务在多个ns,需要多个ns中创建secret
kubectl create secret generic dashboard-tls --from-file=tls.crt --from-file=tls.key -n kube-system
|
3.暴露服务

#应用
kubectl apply -f web.yaml

其中 k8s dashboard 的服务比较特殊,因为原来就是https,需要配置 insecureSkipVerify。
4.配置本地解析

10.*.*.131 traefik.cluster.local
10.*.*.131 grafana.cluster.local
10.*.*.131 dashboard.cluster.local
10.*.*.131 hubble.cluster.local
|
5.使用域名访问相关服务
traefik: https://traefik.cluster.local
dashboard: https://dashboard.cluster.local/
grafana: https://grafana.cluster.local/
hubble: https://hubble.cluster.local/
