參考 https://docs.rancher.cn/docs/rancher2.5/installation/install-rancher-on-k8s/_index

1. 設置 repo

helm repo add rancher-<CHART_REPO> http://rancher-mirror.oss-cn-beijing.aliyuncs.com/server-charts/<CHART_REPO>
替換為 stable

helm repo add rancher-stable http://rancher-mirror.oss-cn-beijing.aliyuncs.com/server-charts/stable

2. 為 Rancher 創建 Namespace

kubectl create namespace cattle-system

3. 選擇您的 SSL 選項 (使用自己簽發的證書)

helm install rancher rancher-stable/rancher \
 --namespace cattle-system \
 --set hostname=k3s.stu77.cn \
 --set replicas=1 \
 --set ingress.tls.source=secret

• 假如出現以下錯誤:
  Error: Kubernetes cluster unreachable: Get "http://localhost:8080/version?timeout=32s": dial tcp 127.0.0.1:8080: connect: connection refused
  或者
  Error: Kubernetes cluster unreachable: the server could not find the requested resource,
  先在 shell 執行 export KUBECONFIG=/etc/rancher/k3s/k3s.yaml (參考 https://blog.csdn.net/varyuan/article/details/112111547)

3.1 自有證書需要添加證書

• 參考 https://docs.rancher.cn/docs/rancher2.5/installation/resources/tls-secrets/_index

kubectl -n cattle-system create secret tls tls-rancher-ingress \
  --cert=/etc/letsencrypt/live/stu77.cn-0001/fullchain.pem \
  --key=/etc/letsencrypt/live/stu77.cn-0001/privkey.pem
