我在用着Telmate 的Terraform 提供程序普罗克斯莫克斯并尝试部署平板车Linux 虚拟机使用云初始化通过传递文件西克. 根据他们的例子，我制作了以下 Terraform 文件：
variable "pve_user" {
}
variable "pve_password" {
}
variable "pve_host" {
}
provider "proxmox" {
pm_tls_insecure = true
pm_api_url = "https://SNIP/api2/json"
pm_user = "SNIP"
pm_password = "SNIP"
pm_parallel = 4
}
resource "null_resource" "cloud_init_config_files" {
connection {
type = "ssh"
user = var.pve_user
password = var.pve_password
host = var.pve_host
}
provisioner "file" {
source = "./templates/cloud-config.yml"
destination = "/var/lib/vz/snippets/cloud-config.yml"
}
}
resource "proxmox_vm_qemu" "k8s-masters" {
depends_on = [
null_resource.cloud_init_config_files
]
count = 1
name = "VM-${count.index}"
clone = "VM-Template"
full_clone = true
target_node = "192.168.20.10"
pool = "VM"
cores = 2
sockets = 1
memory = 10240
network {
id = 0
model = "virtio"
bridge = "vmbr0"
tag = 50
}
disk {
id = 0
type = "scsi"
size = 30
storage = "Pool"
storage_type = "zfspool"
backup = true
iothread = true
}
onboot = true
agent = 1
os_type = "cloud-init"
ssh_user = "core"
cicustom = "user=local:snippets/cloud-config.yml"
ipconfig0 = "ip=192.168.50.10/24,gw=192.168.50.1"
sshkeys = "ssh-rsa SNIP"
ssh_private_key = <<EOF
-----BEGIN RSA PRIVATE KEY-----
SNIP
-----END RSA PRIVATE KEY-----
EOF
}
运行后terraform apply，虚拟机已成功创建，Flatcar 已启动。但是，如果您通过 Proxmox 连接到控制台，虚拟机会显示 IP 地址是通过 DHCP 接收的，而不是我提供的。此外，SSH 密钥不起作用，因此我无法连接到虚拟机进行故障排除。
如果我注释掉该cicustom行，并仅依赖ipconfig0和其他常规选项，则虚拟机会启动，我的 SSH 密钥确实会起作用。但是，指定的 IP 地址仍未使用；虚拟机只是使用 DHCP 提供的 IP 地址。尽管能够访问虚拟机，但我仍然想使用自定义 Cloud Init 配置文件，以便可以访问更强大的配置选项。
我尝试过各种文件组合cloud-config.yml。包括以下简单组合：
hostname: test
更详细地讲，例如：
storage:
files:
- path: /opt/file1
filesystem: root
contents:
inline: Hello, world!
mode: 0644
user:
id: 500
group:
id: 501
passwd:
users:
- name: core
ssh_authorized_keys:
- ssh-rsa SNIP
尽管如此，在我将某些东西传递给 SSH 密钥后，它始终不起作用cicustom，并且基于主机名从未被操纵的事实，我假设 Cloud Init 根本没有收到自定义配置文件。我尝试传递Ignition 和容器 Linux 配置格式化的文件。
Flatcar Linux 是否与 Proxmox/cicustom 不兼容？在 Google 上搜索诸如"flatcar" "proxmox"、"coreos" "proxmox"、"container linux" "proxmox"、"flatcar" "cicustom"等内容似乎没有找到太多结果。我猜没有多少人将云原生操作系统与裸机连接起来？呵呵呵
然而，这个有趣的脚本。第 104-132 行讨论为 Proxmox 创建 Flatcar/CoreOS 模板。所以至少其他人之前做过这个？谁知道他们之后是否传入了自定义云初始化配置文件？
有任何想法吗？

我跟着本指南基本上直接使用 qemu 而不是使用 Proxmox 来完成相同的事情。使用：
这cloud-config.ign：
{
"ignition": { "version": "2.2.0" },
"passwd": {
"users": [
{
"name": "core",
"sshAuthorizedKeys": [
"REDACTED"
]
}
]
},
"storage": {
"files": [{
"filesystem": "root",
"path": "/etc/hostname",
"mode": 420,
"contents": { "source": "data:,test" }
}]
}
}
或这个cloud-config.yml：
hostname: test
passwd:
users:
- name: tj
ssh_authorized_keys:
- REDACTED
都产生相同的结果。无法连接的虚拟机使用主机名启动localhost。
