Packer配置，功能描述

1. AK/SK使用服务器环境变量
2. 基于公共镜像“img-eb30mz89”为基础，在广州，创建临时服务器
3. 使用ansible在临时服务器上进行初始化
4. 初始化完毕后生成镜像
5. 镜像完成后同步至上海、北京、成都、香港

  ]

  provisioner "ansible" {
    playbook_file = "/opt/packer/ansible/tencent-TKE4.yaml"
  }
}


variable "TENCENT_AK" {
  type    = string
  default = env("TENCENT_AK")
}

variable "TENCENT_SK" {
  type    = string
  default = env("TENCENT_SK")
}

variable "IMAGE_NAME" {
  type    = string
  default = "image"
}

使用方式：

如创建腾讯云TKE4镜像，则

cd /opt/packer/tencent
packer build  -var 'IMAGE_NAME=TKE4-20230808'  TKE.pkr.hcl
