Helm Tiller fails to install

kubernetes version : 1.16 Gitlab version : 12.2.5

I intend to integrate kubernets and Gitlab to form a CI/CD environment. But when I try to install "Helm Tiller" from the Gitlab web interface, the following error occurs: 스크린샷_2019-11-10_오후_9.38.02

스크린샷_2019-11-10_오후_9.41.16

스크린샷_2019-11-10_오후_9.41.30

I want help. I would like to refer to here to configure CI/CD. https://medium.com/better-programming/using-a-k3s-kubernetes-cluster-for-your-gitlab-project-b0b035c291a9
