packer - 使用 Packer 构建 RancherOS 时 SSH 失败

Question

我对 Packer 和 RancherOS 有疑问。我正在尝试使用 cloud-config 文件构建自定义 rancherOS 镜像。我正在 MacOSX 上工作。

我有这个build.json文件

{
    "variables": {
        "vm_name" : ""
    },
    "builders": [
        {
            "type": "vmware-iso",
            "iso_url": "rancheros.iso",
            "guest_os_type": "other",
            "iso_checksum_type": "md5",
            "iso_checksum": "467caa8394684ba54e8731aed8480652",
            "output_directory": "output_rancheros",
            "ssh_wait_timeout": "30s",
            "shutdown_command": "sudo shutdown -h now",
            "disk_size": 20000,
            "ssh_username": "rancher",
            "ssh_password": "rancher",
            "ssh_port": 22,
            "ssh_wait_timeout": "90m",
            "vm_name": "{{ user `vm_name` }}",
            "boot_wait": "10s",
            "vmx_data": {
                "memsize": "4096"
            }
        }
    ],
    "provisioners": [
        {
            "type":"file",
            "source": "cloud-config.yml",
            "destination": "/tmp/cloud-config.yml"
        },
        {
            "type": "shell",
            "inline": [
                "sudo ros install -d /dev/sda -f -t generic -c /tmp/cloud-config.yml"
            ]
        }
    ]
}

旁边有一个仅包含我的 SSH key 的 cloud-config.yml

#cloud-config
ssh_authorized_keys:
    - ssh-rsa AAAA....d admin@example.com

当我启动构建命令时packer build build.json

我明白了

    vmware-iso: + umount /mnt/new_img
    vmware-iso: time="2016-07-27T05:52:35Z" level=fatal msg=EOF
    vmware-iso: Continue with reboot [y/N]:
==> vmware-iso: Stopping virtual machine...
==> vmware-iso: Deleting output directory...
Build 'vmware-iso' errored: Script exited with non-zero exit status: 1

==> Some builds didn't complete successfully and had errors:
--> vmware-iso: Script exited with non-zero exit status: 1

==> Builds finished but no artifacts were created.

如果我理解正确的话。我的脚本正在运行，但是当虚拟机重新启动时，新的 SSH key 不起作用。

我不知道如何解决这个问题。也许有人会帮助我。

致以诚挚的问候

我找到了解决办法

只需在 sudo ros install -d/dev/sda -f -t generic -c/tmp/cloud-config.yml 上添加一个 -no-reboot 标志即可> 命令即可完成任务。

因此在生成期间不会进行重新启动。
