[Terraform]Terraform技巧:direnv; Backend, State, Workspace

使用direnv来解决自动AWS Profile导入

1. 先设置AWS profile
2. 安装direnv
3. 在所需目录下新加.envrc文件, 里面放比方：

export AWS_PROFILE=hzhu-nmdev
export TF_VAR_trendmicro_policy_id=3601

4. 最后别忘了在.gitignore里添加**/.envrc，ignore所有.envrc。双*的作用是"to match directories anywhere in the repository."
