运行 shell 通过 terraform 在 AKS 节点池上的脚本或自定义数据

Question

我想通过 Terraform 脚本在 AKS 节点池上运行 shell 脚本或自定义数据。我运行 shell 通过 VMSS（虚拟机规模集）上的自定义数据通过 terraform.Similarly 脚本我想通过 AKS 节点池运行相同的 shell 脚本.我搜索了很多 link 和方法，但找不到任何解决方案。有什么办法或推荐这个吗？感谢您 help.I 一个月以来一直在尝试此解决方案，但未能找到合适的解决方案。

我已经通过 deamonset 和带有 nodeinstaller 的 configmap 得到了我的解决方案。下面的链接确实对我有帮助，但不是通过 terraform，因为 AKS 不支持通过 terraform 自动化的自定义脚本。()
