129. index.yaml 与基于 git 的 Rancher App 仓库中图表显现的优先级

Rancher supports git-based repositories in the Apps feature, enabling deployment of Helm charts into Rancher-managed clusters, from a git repository. An example of such a git repository is provided by the RKE2 cluster template examples at https://github.com/rancher/cluster-template-examples
Rancher 在 Apps 功能中支持基于 git 的仓库 ，使 Helm 图表能够从 git 仓库部署到 Rancher 管理的集群中。RKE2 集群模板示例提供了此类 git 仓库的示例 https://github.com/rancher/cluster-template-examples

Within an Apps git repository, two formats are supported:
在 Apps git 仓库中，支持两种格式：

1. Un-archived and un-compressed Helm charts can be defined within sub-directories of the git repository, as in the example at https://github.com/rancher/cluster-template-examples/tree/main/charts
   未归档和未压缩的 Helm 图表可以在 git 仓库的子目录中定义，如 https://github.com/rancher/cluster-template-examples/tree/main/charts 的示例
2. Archived and compressed Helm charts can be included within the git-repository and referenced from a Helm index.yaml file, as in the example at https://github.com/rancher/cluster-template-examples/blob/main/index.yaml
   归档和压缩后的 Helm 图表可以包含在 git 仓库中，并从 Helm index.yaml 文件中引用，如 https://github.com/rancher/cluster-template-examples/blob/main/index.yaml 的示例

If both formats are present in a single git repository, which takes precedence when Rancher loads available charts?
如果两个格式都存在于同一个 git 仓库中，那么当 Rancher 加载可用图表时，哪个格式优先？

When an index.yaml file is present on the repository, this takes precedence and Rancher will load the list of charts and the referenced chart archives from the index file. This skips the process of walking the repository directory to build the index dynamically from charts in sub-directories.
当仓库中存在 index.yaml 文件时，该文件优先，Rancher 会从索引文件加载图表列表和参考图表存档。这样可以跳过从子目录中的图表动态移动仓库目录来构建索引的过程。
