我的 CodeBuild 项目使用 Packer 和 Ansible provisioner 创建 AMI。
这个 Packer 设置在我本地环境和 Amazon Linux2 EC2 环境中都成功了。但是，当我使用 AWS CodeBuild 并选择 aws/codebuild/amazonlinux2-x86_64-standard:1.0 镜像时，它就失败了。
我已经尝试了这些设置 remote_tmp = /tmp 或者 remote_tmp = /tmp/.ansible-${USER}/tmp，但都没有起作用。

我知道它失败了，因为它尝试创建
/root 目录而被拒绝权限。但我不知道它为什么要尝试创建 /root 目录。我该如何更改这种行为？
