環境

[root@kubernetes-master-001 centos]# helm version

問題

我正在嘗試在離線環境中設置 helm，但我被卡住了。

我似乎成功通過了這init一步，但任何呼叫都install失敗了：

[root@kubernetes-master-001 centos]# export HELM_HOME=/root/.helm
[root@kubernetes-master-001 centos]# helm init --service-account tiller --wait -i $local_registry/kubernetes-helm/tiller:v2.9.0 --skip-refresh

[root@kubernetes-master-001 centos]# helm install $local_HTTP_server/nginx-ingress-869c634517dbeb94c4a759fcfb69c44da38007ed.tgz --debug --name my-nginx --set rbac.create=true
[debug] Created tunnel using local port: '34825'
[debug] SERVER: "127.0.0.1:34825"
[debug] Original chart version: ""
Error: no cached repo found. (try 'helm repo update'). open /root/.helm/repository/cache/stable-index.yaml: no such file or directory

這可以在以下位置找到$HELM_HOME：

[root@kubernetes-master-001 centos]# find "$HELM_HOME" -type f
/root/.helm/repository/local/index.yaml
/root/.helm/repository/repositories.yaml

有沒有人看到這個解決方案？

因此，基於此 github 評論，我執行了一個（骯髒的）解決方法：

該程序$HELM_HOME/repository/local/index.yaml創建了一個文件。helm init

[root@kubernetes-master-001 centos]# cat "$HELM_HOME/repository/local/index.yaml"
apiVersion: v1
entries: {}
generated: 2018-06-25T11:48:14.734541008Z

我複制了它@ $HELM_HOME/repository/cache/stable-index.yaml：

cp "$HELM_HOME/repository/local/index.yaml" "$HELM_HOME/repository/cache/stable-index.yaml"

之後效果很好：

[root@kubernetes-master-001 centos]# helm install $local_HTTP_server/nginx-ingress-869c634517dbeb94c4a759fcfb69c44da38007ed.tgz --debug --name my-nginx --set rbac.create=true
