保存状态失败：打开terraform.tfstate：权限被拒绝

Question

我正在尝试使用Terraform创建AWS EC2实例。

$ terraform apply

我得到执行上述命令后的输出如下。

aws_instance.example: Creating... 
    ami:       "" => "ami-2d39803a" 
    associate_public_ip_address: "" => "<computed>" 
    availability_zone:   "" => "<computed>" 
    ebs_block_device.#:   "" => "<computed>" 
    ephemeral_block_device.#: "" => "<computed>" 
    instance_state:    "" => "<computed>"

Failed to save state: open terraform.tfstate: permission denied 

虽然EC2实例被创建，但我的基础设施的状态不会被保存，你可以在控制台输出的最后一行注意。

在拼命寻找解决方案后，我偶然检查了放置我的terraform文件的目录的访问权限。

主目录的权限被设置为只读。我做了适当的修改，现在terraform apply工作得很好。
