终止具有非零退出状态的源后，Packer 失败：2

Question

我正在尝试使用 packer 和 ansible 创建一个新的 ami。诚然，我对两者都很陌生。（我过去使用过 fabric 和 puppet。）我注意到我使用的是 amazon linux base ami，因此决定改用 centos 映像。这带来了一些我已经克服的障碍。但是，我现在收到以下错误。它发生在 "Terminating the source AWS instance..."

之后似乎很奇怪

==> amazon-ebs: Terminating the source AWS instance...
==> amazon-ebs: No AMIs to cleanup
==> amazon-ebs: Deleting temporary security group...
==> amazon-ebs: Deleting temporary keypair...
Build 'amazon-ebs' errored: Script exited with non-zero exit status: 2

==> Some builds didn't complete successfully and had errors:
--> amazon-ebs: Script exited with non-zero exit status: 2

==> Builds finished but no artifacts were created.

包装器 json 是：

            ]
        }
    ]
}

我使用的基础镜像是ami-d440a6e7。

任何指导将不胜感激。我还没有找到退出代码 2 或类似的东西。

更新

我已通过删除以下行确定：

"sudo update-alternatives --set python /usr/bin/python2.7",

从最后一个 shell provisioner 看来，它似乎完成了该步骤并移至 ansible。但是，ansible 失败了，因为它取决于 python2.7

Answer 1

好的，看来通过删除

"sudo update-alternatives --set python /usr/bin/python2.7",

我能够克服上述错误并发现由于我的 ansible playbook 检查的几个 python 依赖项在 centos yum 回购中的名称与它们在亚马逊-linux 回购。例如，python27-setuptools 就是 python-setuptools，python27-Cython 就是 Cython。

感谢大家的帮助和指导！

Answer 2

感谢 post。这引导我在尝试运行一些脚本（vmware 工具安装）时解决几乎类似的问题。

问题是我运行在 vmtools 脚本 rum 之前使用我的清理脚本，这意味着一些必需的文件已经丢失。

vmware-iso: tar: /tmp/VMwareTools-*.tar: Cannot open: No such file or directory
vmware-iso: tar: Error is not recoverable: exiting now

==> vmware-iso：正在停止虚拟机... ==> vmware-iso：删除输出目录... 生成 'vmware-iso' 出错：脚本以非零退出状态退出：2

这是我的配置脚本：

provisioners": [
  "execute_command": "echo 'rhel' | {{.Vars}} sudo -S -E sh -eux '{{.Path}}'",
  "scripts": [
    "scripts/common/metadata.sh",
    "scripts/centos/networking.sh",
    "scripts/common/sshd.sh",
    "scripts/rhel-ec/rhel-user.sh",
    "scripts/rhel-ec/vmtools.sh",
    "scripts/rhel-ec/cleanup.sh",
    "scripts/centos/cleanup.sh",
    "scripts/common/minimize.sh"
  ],
  "type": "shell"
}

],

解决办法是安排我的脚本。这意味着运行在 cleanup.sh 运行.

之前先执行 vmtools.sh 脚本
