我从 ubuntu shell 运行以下命令，与 AWS 平台通信：
$ packer build -debug template.packer
Debug mode enabled. Builds will not be parallelized.
amazon-ebs output will be in this color.
==> amazon-ebs: Prevalidating AMI Name...
==> amazon-ebs: Pausing after run of step 'StepPreValidate'. Press enter to continue.
==> amazon-ebs: Inspecting the source AMI...
==> amazon-ebs: Pausing after run of step 'StepSourceAMIInfo'. Press enter to continue.
==> amazon-ebs: Creating temporary keypair: packer 5dfe9f3b-9cc2-cbfa-7349-5c8ef50c64d5
amazon-ebs: Saving key for debug purposes: ec2_amazon-ebs.pem
==> amazon-ebs: Pausing after run of step 'StepKeyPair'. Press enter to continue.
哪里template.packer：

我的理解是，AWS 已经为打包程序创建了一个私钥（ec2_amazon-ebs.pem），以便以无密码方式与 EC2 实例通信，如上述步骤中所述。
但我没有看到打包程序在我的笔记本电脑中复制私钥ec2_amazon-ebs.pem（因为~/.ssh/ec2_amazon-ebs.pem）
打包程序如何与 EC2 通信？无需像~/.ssh/ec2_amazon-ebs.pem在笔记本电脑中那样进行复制
