前提条件
安装 Terraform
腾讯云 Cloud Shell 是一款帮助您运维的免费产品，预装了 Terraform 相关组件，并配置好腾讯云临时凭证（credentials）。
如果您不使用 Cloud Shell，关于安装 Terraform 的具体操作，请参见在 本地安装和配置 Terraform。
说明：
Terraform 安装版本不得低于 v1.6.3，可通过 terraform --version 命令查看安装后 Terraform 版本。
若您是云端管理，可前往 云端安装，云端安装获取访问密钥与本地相同。
配置腾讯云账号信息
在首次使用 Terraform 之前，请前往 云 API 密钥页面 申请安全凭证 SecretId 和 SecretKey。若已有可使用的安全凭证，则跳过该步骤。
1. 登录 访问管理控制台，在左侧导航栏，选择访问密钥 > API 密钥管理。
2. 在 API 密钥管理页面，单击新建密钥，即可以创建一对 SecretId / SecretKey。
配置腾讯云账号信息，有以下两种方式：
静态凭证鉴权
在用户目录下创建 provider.tf 文件，输入如下内容。其中my-secret-id 和 my-secret-key  需替换为密钥 SecretId 和 SecretKey。
provider "tencentcloud" {
  secret_id = "my-secret-id"
  secret_key = "my-secret-key"
}
环境变量鉴权
配置电脑环境变量或云端环境变量，请执行以下命令。其中YOUR_SECRET_ID 和 YOUR_SECRET_KEY 需替换为密钥 SecretId 和 SecretKey。
export TENCENTCLOUD_SECRET_ID=YOUR_SECRET_ID
export TENCENTCLOUD_SECRET_KEY=YOUR_SECRET_KEY
增加 Prometheus 实例的采集容器监控数据
1. 创建一个新的 Terraform 配置文件：创建一个新目录，并在该目录下创建一个名为 main.tf 的文件，配置如下信息：
# 指定 provider 配置信息
﻿
terraform {
  required_providers {
    tencentcloud = {
      source = "tencentcloudstack/tencentcloud"
    }
  }
}
# prometheus管理云监控集成
﻿
#prometheus 管理容器集群(采集容器)
﻿
resource "tencentcloud_monitor_tmp_tke_cluster_agent" "foo" {
  instance_id = tencentcloud_monitor_tmp_instance.foo.id
  agents {
    region          = "ap-mumbai"
    cluster_type    = "eks"
    cluster_id      = "cls-1uary7z2" #需要关联的集群id
    enable_external = false
  }
}
说明：
创建 Prometheus 实例的集成中心组件需配置对应参数，需配置的字段如下：
instance_id: （必填、字符串、ForceNew）实例 ID。
agents ：（必填，列表）代理列表。 
cluster_id ：（必填，字符串）标识集群的 id。
region：（必填，字符串）区域限制。
enable_external： (必填，Bool) 是否开启公网 CLB。
cluster_type:（必填，字符串）集群类型。
您若需要获取更多详细参数请参考 腾讯接入云集成接入 github，也可以通过 Terraform 腾讯云提供商 了解更多。
2. 初始化 Terraform 运行环境，执行命令如下：
terraform init
预期输出信息：
Initializing the backend...
﻿
Initializing provider plugins...
- Reusing previous version of tencentcloudstack/tencentcloud from the dependency lock file
- Using previously-installed tencentcloudstack/tencentcloud v1.81.32
﻿
Terraform has been successfully initialized!
﻿
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
﻿
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
3. 生成资源规划，执行命令如下：
  terraform plan
预期输出信息：
tencentcloud_monitor_tmp_instance.foo: Refreshing state... [id=prom-jh0zntj2]
tencentcloud_monitor_tmp_exporter_integration.tmpExporterIntegration: Refreshing state... [id=balck-box-tf-test#prom-jh0zntj2#1##blackbox-exporter]
tencentcloud_monitor_tmp_exporter_integration.tmpExporterMointor: Refreshing state... [id=tf-test-cjtest#prom-jh0zntj2#1##qcloud-exporter]
﻿
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
  + create
﻿
Terraform will perform the following actions:
﻿
  # tencentcloud_monitor_tmp_tke_cluster_agent.foo will be created
  + resource "tencentcloud_monitor_tmp_tke_cluster_agent" "foo" {
      + id          = (known after apply)
      + instance_id = "prom-jh0zntj2"
﻿
      + agents {
          + cluster_id      = "cls-1uary7z2"
          + cluster_name    = (known after apply)
          + cluster_type    = "eks"
          + enable_external = false
          + region          = "ap-mumbai"
          + status          = (known after apply)
        }
    }
﻿
Plan: 1 to add, 0 to change, 0 to destroy.
﻿
───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
﻿
Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if
you run "terraform apply" now.
4. 创建集成中心组件集成，执行命令如下：
   terraform apply
预期输出信息：
tencentcloud_monitor_tmp_instance.foo: Refreshing state... [id=prom-jh0zntj2]
tencentcloud_monitor_tmp_exporter_integration.tmpExporterIntegration: Refreshing state... [id=balck-box-tf-test#prom-jh0zntj2#1##blackbox-exporter]
tencentcloud_monitor_tmp_exporter_integration.tmpExporterMointor: Refreshing state... [id=tf-test-cjtest#prom-jh0zntj2#1##qcloud-exporter]
﻿
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
  + create
﻿
Terraform will perform the following actions:
﻿
  # tencentcloud_monitor_tmp_tke_cluster_agent.foo will be created
  + resource "tencentcloud_monitor_tmp_tke_cluster_agent" "foo" {
      + id          = (known after apply)
      + instance_id = "prom-jh0zntj2"
﻿
      + agents {
          + cluster_id      = "cls-1uary7z2"
          + cluster_name    = (known after apply)
          + cluster_type    = "eks"
          + enable_external = false
          + region          = "ap-mumbai"
          + status          = (known after apply)
        }
    }
﻿
Plan: 1 to add, 0 to change, 0 to destroy.
﻿
Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.
﻿
  Enter a value: yes
﻿
tencentcloud_monitor_tmp_tke_cluster_agent.foo: Creating...
实例内容。。。
﻿
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
查看 Prometheus 实例状态
登录  腾讯云可观测平台，在左侧导航栏，选择 prometheus 监控 ，可在 prometheus 实例列表中看到存在的实例。
删除 Prometheus 实例集成中心组件集成
销毁资源，执行命令如下：
terraform destroy
预期输出信息：
tencentcloud_monitor_tmp_instance.foo: Refreshing state... [id=prom-8dyb6iny]
﻿
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
  - destroy
﻿
Terraform will perform the following actions:
实例内容。。。
﻿
Plan: 0 to add, 0 to change, 1 to destroy.
﻿
Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.
﻿
  Enter a value: yes
﻿
tencentcloud_monitor_tmp_instance.foo: Destroying... [id=prom-8dyb6iny]
tencentcloud_monitor_tmp_instance.foo: Destruction complete after 6s
﻿
Destroy complete! Resources: 1 destroyed.
注意：
当出现 Destroy complete! Resources: （存在的实例个数） destroyed. 表示您已删除该实例。
