同步你的存储库
此示例专门用于提供chart存储库的Google Cloud Storage（GCS）存储。
先决条件
设置本地chart存储库目录
像我们在chart存储库指南中一样创建一个本地目录，并将打包的chart放入该目录中。
例如:
$ mkdir fantastic-charts
$ mv alpine-0.1.0.tgz fantastic-charts/
生成更新的INDEX.YAML
使用helm通过将远程存储库的目录路径和URL传递到helm repo index命令来生成更新的index.yaml文件，如下所示：
$ helm repo index fantastic-charts/ --url https://fantastic-charts.storage.googleapis.com
这将生成一个更新的index.yaml文件并放置在fantastic-charts/目录中。
同步您的本地和远程chart存储库
通过运行将目录的内容上传到您的GCS存储，scripts/sync-repo.sh并传入本地目录名称和GCS存储名称。
$ pwd
/Users/funuser/go/src/github.com/kubernetes/helm
$ scripts/sync-repo.sh fantastic-charts/ fantastic-charts
Getting ready to sync your local directory (fantastic-charts/) to a remote repository at gs://fantastic-charts
Verifying Prerequisites....
Thumbs up! Looks like you have gsutil. Let's continue.
Building synchronization state...
Starting synchronization
Would copy file://fantastic-charts/alpine-0.1.0.tgz to gs://fantastic-charts/alpine-0.1.0.tgz
Would copy file://fantastic-charts/index.yaml to gs://fantastic-charts/index.yaml
Are you sure you would like to continue with these changes?? [y/N]} y

Starting synchronization
Copying file://fantastic-charts/alpine-0.1.0.tgz [Content-Type=application/x-tar]...
Uploading gs://fantastic-charts/alpine-0.1.0.tgz: 740 B/740 B
Copying file://fantastic-charts/index.yaml [Content-Type=application/octet-stream]...
Uploading gs://fantastic-charts/index.yaml: 347 B/347 B
Congratulations your remote chart repository now matches the contents of fantastic-charts/
更新您的chart存储库
您需要保留chart存储库内容的本地副本，或者gsutil rsync将远程chart存储库的内容复制到本地目录。
$ gsutil rsync -d -n gs://bucket-name local-dir/ # the -n flag does a dry run

Starting synchronization
Would copy gs://bucket-name/alpine-0.1.0.tgz to file://local-dir/alpine-0.1.0.tgz
Would copy gs://bucket-name/index.yaml to file://local-dir/index.yaml
$ gsutil rsync -d gs://bucket-name local-dir/ # performs the copy actions
