terraform简单的开始-vpc cvm创建

saynaihe2023-09-23 17:47

从网络开始

从创建VPC开始

复用前面的main.tf的代码：

terraform {
  required_providers {
    tencentcloud = {
      source = "tencentcloudstack/tencentcloud"
      version = "1.81.25"
    }
  }
}
variable "region" {
  description = "腾讯云地域"
  type    = string
  default     = "ap-chongqing"
}
variable "secret_id" {}
variable "secret_key" {}

# 设置腾讯云提供者
provider "tencentcloud" {
  secret_id  =var.secret_id
  secret_key = var.secret_key 
  region = var.region
}

注意：region这里为修改成了重庆，因为我重庆没有资源，想区分一下！

创建VPC这里还好,看一下腾讯云控制台：

一个 resource 块包含 resource 关键字 、资源类型 、资源名 和资源块体三部分。这是terraform中创建资源常用的格式！

vpc相关代码：

至于VPC的创建可以根据官方文档进行创建：

resource "tencentcloud_vpc" "vpc" {
  cidr_block       = "10.0.0.0/16"
  name         = "zhangpeng-vpc"
  is_multicast = false
}

terraform plan ：

terraform plan -var-file=credentials.tfvars

terraform apply:

terraform apply -var-file=credentials.tfvars

这里要输入Y确认！，打印的可用区那些输出是开始做实验的残留，虽然代码中删除了。但是state状态里面还是有记录的，忽略

控制台确认：

登陆控制台确认一下：

顺便output一下：

创建成功，接着问题就又来了：我不想取控制台查看。我如何在terraform中返回创建的信息呢？我可以output一下？

output "vpc" {
  value = tencentcloud_vpc.vpc
}

这里直接忽略了plan 直接apply了：

terraform apply -var-file=credentials.tfvars

子网subnet与可用区

可用区随机

输出了VPC的相关信息。紧接着。我这里创建subset第一次出现了纠结：先忽略 vpc subset子网，这里还有一个名词可用区。创建cvm要先选择可用区，重庆还好只有一个可用区：

但是上海这样的都有好几个可用区：

subnet代码：

可用区跟子网的创建我这里徘徊了一下。先说一下我的苯方法：

先查询区域下可用区列表，根据可用区数量创建subset。创建资源（cvm mysql redis等资源）随机可用区。这里的代码用到了**locals块（**chatgpt生成的）

# 获取可用区列表
data "tencentcloud_availability_zones" "availability_zones" {}
output "availability_zones" {
  value = values(data.tencentcloud_availability_zones.availability_zones)
}
locals {
  availability_zones_list = data.tencentcloud_availability_zones.availability_zones.zones[*].name
  availability_zones_number_list = [for zone in local.availability_zones_list : substr(zone, length(zone) - 1, 1)]
}

resource "tencentcloud_subnet" "my_subnets" {
  count               = length(local.availability_zones_list)

  vpc_id              = tencentcloud_vpc.vpc.id
  cidr_block          = cidrsubnet(tencentcloud_vpc.vpc.cidr_block, 8, tonumber(substr(local.availability_zones_list[count.index], length(local.availability_zones_list[count.index]) - 1, 1)))
  availability_zone   = local.availability_zones_list[count.index]
  name                = format("subnet-%s", substr(local.availability_zones_list[count.index], length(local.availability_zones_list[count.index]) - 1, 1))
}
output "subnets" {
  value = tencentcloud_subnet.my_subnets[*]
}

terraform plan

terraform plan -var-file=credentials.tfvars

terraform apply

terraform apply -var-file=credentials.tfvars

也可以控制台看一下：

这里只有一个还没有好的展示出来。完整输出后到一个多可用区的区域试一下，毕竟这里只是随机可用的设想！

安全组security_group

安全组代码：

接下来应该是到了安全组防火墙的创建了：直接参考tencentcloud_security_group

resource "tencentcloud_security_group" "zhangpeng_sg" {
  name = "zhangpeng-sg"
}

resource "tencentcloud_security_group_lite_rule" "zhangpeng_sg_rule" {
  security_group_id = tencentcloud_security_group.zhangpeng_sg.id
  ingress = [
    "ACCEPT#10.0.0.0/16#ALL#ALL",
    "ACCEPT#0.0.0.0/0#22#TCP"
  ]

  egress = [
    "ACCEPT#0.0.0.0/0#ALL#ALL"
  ]
}

terraform plan and terraform apply

 terraform plan -var-file=credentials.tfvars

 terraform apply -var-file=credentials.tfvars


吐槽一下aigc生成：

吐槽一下，chatgpt生成会各种坑的：

这里生成代码错误了，自己记得各种校验！

从cvm开始

cvm简单实例的创建

cvm相关代码：

正常流程是创建一个tencentcloud_instance，下面应该是一个最简单的例子：

resource "tencentcloud_instance" "my_instance" {
  instance_name     = "my-instance"
  image_id          = "img-xxxxxx"  # 替换为实际的镜像ID
  instance_type     = "S2.SMALL2"
  vpc_id            = tencentcloud_vpc.vpc.id
  subnet_id         = tencentcloud_subnet.my_subnet.id
  security_groups   = [tencentcloud_security_group.zhangpeng_sg.id]
  login_settings {
    password = "MyPassw0rd!"  # 替换为实际的登录密码
  }
}

按照文档的实例与上面网络的部分整合得到下面的代码：

terraform {
  required_providers {
    tencentcloud = {
      source  = "tencentcloudstack/tencentcloud"
      version = "1.81.25"
    }
  }
}

variable "region" {
  description = "腾讯云地域"
  type        = string
  default     = "ap-chongqing"
}

variable "secret_id" {}
variable "secret_key" {}

# 设置腾讯云提供者
provider "tencentcloud" {
  secret_id  = var.secret_id
  secret_key = var.secret_key
  region     = var.region
}

# 创建VPC
resource "tencentcloud_vpc" "vpc" {
  cidr_block    = "10.0.0.0/16"
  name          = "zhangpeng-vpc"
  is_multicast  = false
}

output "vpc" {
  value = tencentcloud_vpc.vpc
}

# 获取可用区列表
data "tencentcloud_availability_zones" "availability_zones" {}

output "availability_zones" {
  value = data.tencentcloud_availability_zones.availability_zones
}

locals {
  availability_zones_list          = data.tencentcloud_availability_zones.availability_zones.zones[*].name
  availability_zones_number_list   = [for zone in local.availability_zones_list : substr(zone, length(zone) - 1, 1)]
}

resource "tencentcloud_subnet" "my_subnets" {
  count             = length(local.availability_zones_list)
  vpc_id            = tencentcloud_vpc.vpc.id
  cidr_block        = cidrsubnet(tencentcloud_vpc.vpc.cidr_block, 8, tonumber(substr(local.availability_zones_list[count.index], length(local.availability_zones_list[count.index]) - 1, 1)))
  availability_zone = local.availability_zones_list[count.index]
  name              = format("subnet-%s", substr(local.availability_zones_list[count.index], length(local.availability_zones_list[count.index]) - 1, 1))
}

output "subnets" {
  value = tencentcloud_subnet.my_subnets[*]
}

resource "tencentcloud_security_group" "zhangpeng_sg" {
  name = "zhangpeng-sg"
}

resource "tencentcloud_security_group_lite_rule" "zhangpeng_sg_rule" {
  security_group_id = tencentcloud_security_group.zhangpeng_sg.id

  ingress = [
    "ACCEPT#10.0.0.0/16#ALL#ALL",
    "ACCEPT#0.0.0.0/0#22#TCP",
  ]

  egress = [
    "ACCEPT#0.0.0.0/0#ALL#ALL",
  ]
}

resource "random_integer" "zone_index" {
  min = 0
  max = length(local.availability_zones_list) - 1
}

data "tencentcloud_subnet" "my_subnet" {
  vpc_id             = tencentcloud_vpc.vpc.id
  subnet_id          = tencentcloud_subnet.my_subnets[random_integer.zone_index.result].id
}

data "tencentcloud_images" "my_favorite_image" {
  image_type = ["PUBLIC_IMAGE"]
  os_name    = "centos 8"
}

output "my_favorite_image_id" {
  value = data.tencentcloud_images.my_favorite_image.images[0].image_id
}

data "tencentcloud_instance_types" "my_favorite_instance_types" {
  filter {
    name   = "instance-family"
    values = ["S1", "S2", "S3", "S4", "S5"]
  }

  cpu_core_count   = 2
  memory_size      = 4
  exclude_sold_out = true
}

resource "tencentcloud_instance" "cvm_postpaid" {
  instance_name      = "cvm_postpaid"
  availability_zone  = data.tencentcloud_subnet.my_subnet.availability_zone
  image_id           = data.tencentcloud_images.my_favorite_image.images[0].image_id
  instance_type      = data.tencentcloud_instance_types.my_favorite_instance_types.instance_types[0].instance_type
  system_disk_type   = "CLOUD_PREMIUM"
  system_disk_size   = 50
  password = "uyiSkVaEYZOvnCYK"
}

**tencentcloud_images **这里为本来还想取最新的镜像但是他默认的就是从最新的开始的了。也不用做任何复杂处理了 **password **设置一个简单密码.

执行terraform plan

terraform plan -var-file=credentials.tfvars

特意看了一下image_id 参照：https://cloud.tencent.com/document/product/213/46059

当然了CentOS Stream 8 跟centos8 毕竟是不一样的。这里应该都知道的！
执行terraform apply

terraform apply -var-file=credentials.tfvars

报错：

[TencentCloudSDKError] Code=InvalidParameterValue.InvalidPassword, Message=The specified password `uyiSkVaEYZOvnCYK` is invalid., RequestId=12c6f920-624b-4ec5-a41b-4ddb336052a0

不细看就应该是密码不符合策略？加一下特殊符号：

修改 **password **= "BRmZEktDc2&D2@&b"

terraform apply -var-file=credentials.tfvars


继续完善一下：完成公网IP绑定，output输出cvm信息

恩大致可以了 然后ssh 试一下：

复杂一些ssh密钥 and多实例

ssh 密钥生成

接下来： 生成挂载ssh-key 恩我想一起生成多台cvm.由于我默认有ssh key。默认ssh-keygen 会覆盖的。指定目录生成一个新的ssh-key：

[zhangpeng@zhangpeng terraform-tencent]$ mkdir ssh-key
[zhangpeng@zhangpeng terraform-tencent]$ pwd
/home/zhangpeng/vscode/terrform/terraform-tencent
ssh-keygen -t rsa -b 2048 -f /home/zhangpeng/vscode/terrform/terraform-tencent/ssh-key/private_key



生成相关代码：

将private_key.pub 放入tencentcloud_key_pair 代码块：

resource "tencentcloud_key_pair" "ssh_key_pair" {
  key_name = "zhangpeng_key"
  public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDJJRI8XVb5FFQydPEpw5MwwOajzmDMZVpwdHX8P2j9HKu3uBcKX5LnejxAH2EHPIgz5DI0tlsU4lvoh8fUpsg6PjHcZuF6P/vWKnnShCE20HJ/qBYKcdXX2LDRMb/tVjBq9hBkG7+PC7mb3lsS/1xJidjkkz103ZJZx0ysx89wtfkPts6cEcGm4ReuPES3y8bje51zZ9d/iZBtZPXAnW6ICWlbrAll+cBHSv6PRMnz0h3Ke+tr2hckXkucPl1VryXyJ/Kv5m0VKKvsDi0OmUK2PY1XdrQBrFuXcxa5iWQcnKbL5lPSOAwGPjuZQdYMB+mxqzYRDuZSZhg5zhY6KC/N zhangpeng@xxxx"
}

增加一个instance_count 的变量控制cvm数量

variable "instance_count" {
  default = 2
}

最终代码如下：

特别强调一下：

过去记得还是key_name 。现在貌似key_ids 了

terraform plan and terraform apply

terraform plan -var-file=credentials.tfvars

terraform apply -var-file=credentials.tfvars

报错

会报错： 因为第一台cvm之前设置过密码：

但是不影响第二台的创建，这里很不人性化,我也不想做各种复杂的处理了：

清理环境重新走一遍：

terraform destroy -var-file=credentials.tfvars

重新来一遍：

terraform apply -var-file=credentials.tfvars

ssh登陆测试：

ssh -i ssh-key/private_key root@139.186.219.45
ssh -i ssh-key/private_key root@139.186.200.103

对了这里忘了绑定安全组：

      public_ip     = instance.public_ip
      instance_name = instance.instance_name
      # 其他您感兴趣的实例信息字段
    }
  }
}

继续plan apply:

terraform plan -var-file=credentials.tfvars
terraform apply -var-file=credentials.tfvars

控制台查看cvm绑定了安全组：

总结

关于网络跟cvm 主机设置主要就是这些，无非启用公网ip,配置安全组，主机名自定义？当然还有local 安装包之类的操作。唯一最不爽的就是启用了密码，修改为ssh-key的时候的不顺畅...继续清理环境：

terraform destroy -var-file=credentials.tfvars

继续完成其他的操作！
