原因分析：
原始的 Catelog system-library 是 Rancher 自带的，使用 release-v2.6 分支；
解决方案：
修改系统 Catelog 配置，将 system-library 的 branche 设置为 master；
部署 Helm 应用失败；helm-operation … ErrImagePull …
问题描述：在 Rancher 中，通过 Helm 部署应用失败；
原因分析：我们看到 helm-operation-6dvgh 拉取镜像失败，我们猜测是：helm operation Pod 负责 Helm 部署，而镜像拉取失败导致出现该错误；

解决方案：我们尝试修改 rancher/shell 镜像的地址：
// 我们尝试修改 Helm Chart values.yaml 文件 // postDelete.image.repository，但似乎并未生效，从参数名来看也与该参数无关； // 根据社区反馈：https://forums.rancher.com/t/how-can-i-change-the-rancher-shell-image/36630 // 应该修改 CR 的配置 # kubectl edit settings.management.cattle.io ... default: rancher/shell:v0.1.10 ...
