同步你的仓库
注意：该示例是专门针对Google Cloud Storage（GCS）提供的chart仓库。
先决条件
安装gsutil工具。我们非常依赖gsutil rsync功能
https://cloud.google.com/storage/docs/gsutil
确保可以使用Helm程序
可选：我们推荐在您的GCS中设置 对象版本 以防不小心删除了什么。
设置本地chart仓库目录
就像我们在 chart仓库指南 做的，创建一个本地目录，并将打包好的chart放在该目录中。
例如：
$ mkdir fantastic-charts
$ mv alpine-0.1.0tgz fantastic-charts/
$ mkdir fantastic-charts
$ mv alpine-0.1.0.tgz fantastic-charts/生成新的index.yaml
使用Helm生成新的index.yaml文件，通过将目录路径和远程仓库url传递给helm repo index命令：
$ helm repo index fantastic-charts/ --url https://fantastic-charts.storage.googleapis.com
$ helm repo index fantastic-charts/ --url https://fantastic-charts.storage.googleapis.com
这会生成新的index.yaml文件并放在fantastic-charts/目录。
同步本地和远程仓库
使用scripts/sysnc-repo.sh命令上传GSC目录中的内容并传入本地目录名和GCS名。
例如：
$ pwd
$ scripts/sync-repo.sh fantastic-charts/ fantastic-charts
$ pwd
/Users/me/code/go/src/helm.sh/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仓库
您需要保留chart仓库内容的本地副本或使用gsutil rsync拷贝远程chart仓库内容到本地目录。
例如：
$ gsutil rsync -d -n gs://bucket-name local-dir/ # the -n flag does a dry run
$ gsutil rsync -d gs://bucket-name local-dir/ # performs ths copy actions
$ 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
