关于腾讯云:terraform简单的开始vpc-cvm创建

作者：

在

从网络开始

从创立VPC开始

复用后面的main.tf的代码：

terraform {
  required_providers {
    tencentcloud = {
      source = "tencentcloudstack/tencentcloud"
      version = "1.81.25"
    }
  }
}
variable "region" {
  description = "腾讯云地区"
  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
}

留神：region这里为批改成了重庆，因为我重庆没有资源，想辨别一下！
创立VPC这里还好,看一下腾讯云控制台：

一个 resource 块蕴含 resource 关键字、资源类型、资源名和资源块体三局部。这是terraform中创立资源罕用的格局！

vpc相干代码：

至于VPC的创立能够依据官网文档进行创立：

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

这里要输出Y确认！，打印的可用区那些输入是开始做试验的残留，尽管代码中删除了。然而state状态外面还是有记录的，疏忽

控制台确认：

登陆控制台确认一下：

顺便output一下：

创立胜利，接着问题就又来了：我不想取控制台查看。我如何在terraform中返回创立的信息呢？我能够output一下？

output "vpc" {
  value = tencentcloud_vpc.vpc
}

这里间接疏忽了plan 间接apply了：

terraform apply -var-file=credentials.tfvars

子网subnet与可用区

可用区随机

输入了VPC的相干信息。紧接着。我这里创立subset第一次呈现了纠结：先疏忽 vpc subset子网，这里还有一个名词可用区。创立cvm要先抉择可用区，重庆还好只有一个可用区：

然而上海这样的都有好几个可用区：

subnet代码：

可用区跟子网的创立我这里彷徨了一下。先说一下我的苯办法：
先查问区域下可用区列表，依据可用区数量创立subset。创立资源（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

也能够控制台看一下：

这里只有一个还没有好的展现进去。残缺输入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构想！

平安组security_group

平安组代码：

接下来应该是到了平安组防火墙的创立了：间接参考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：

这里生成代码谬误了，本人记得各种校验！

从cvm开始

cvm简略实例的创立

cvm相干代码：

失常流程是创立一个tencentcloud_instance，上面应该是一个最简略的例子：

resource "tencentcloud_instance" "my_instance" {
  instance_name     = "my-instance"
  image_id          = "img-xxxxxx"  # 替换为理论的镜像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!"  # 替换为理论的登录明码
  }
}

依照文档的实例与下面网络的局部整合失去上面的代码：

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

variable "region" {
  description = "腾讯云地区"
  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
}

# 创立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 = [

  ]
}

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 这里为原本还想取最新的镜像然而他默认的就是从最新的开始的了。也不必做任何简单解决了 password 设置一个简略明码.

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。这里应该都晓得的！
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

不细看就应该是明码不合乎策略？加一下特殊符号：
批改 password = “BRmZEktDc2&D2@&b”

terraform apply -var-file=credentials.tfvars

恩大抵能够了 而后ssh 试一下：

简单一些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.因为我默认有ssh key。默认ssh-keygen 会笼罩的。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

生成相干代码：

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"
}

减少一个instance_count 的变量管制cvm数量

特别强调一下：

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之前设置过明码：

然而不影响第二台的创立，这里很不人性化,我也不想做各种简单的解决了：

清理环境从新走一遍：

terraform destroy -var-file=credentials.tfvars

从新来一遍：

terraform apply -var-file=credentials.tfvars

ssh登陆测试：

ssh -i ssh-key/private_key root@139.186.219.45

持续plan apply:

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

控制台查看cvm绑定了平安组：

总结

对于网络跟cvm 主机设置次要就是这些，无非启用公网ip,配置平安组，主机名自定义？当然还有local 安装包之类的操作。惟一最不爽的就是启用了明码，批改为ssh-key的时候的不顺畅…..持续清理环境：

terraform destroy -var-file=credentials.tfvars

持续实现其余的操作！
