      Prerequisites

      Installing Terraform

      For detailed instructions on installing Terraform, see Installing Terraform.
      Note:
      The installed version of Terraform must not be below v1.6.3. You can verify the version of Terraform installed by using the command terraform --version.

      Configuring Tencent Cloud Account Information

      Before using Terraform for the first time, go to API Key to apply for a SecretID and SecretKey of the security credentials. If you already have valid credentials, skip this step.
      1. Log in to the CAM Console and choose Access Key > API Keys from the left sidebar.
      2. On the API Keys page, click Create Key to create a SecretId/SecretKey pair.

      There are two methods for configuring Tencent Cloud account information:

      Authentication by Static Credentials
      Create a provider.tf file in the user directory with the following content. Replace my-secret-id and my-secret-key with your SecretId and SecretKey, respectively.
      provider "tencentcloud" {
        secret_id = "my-secret-id"
        secret_key = "my-secret-key"
      }
      Authentication by Environment Variables
      Set the computer variables or cloud environment variables by running the command below. Replace YOUR_SECRET_ID and YOUR_SECRET_KEY with your SecretId and SecretKey, respectively.
      export TENCENTCLOUD_SECRET_ID=YOUR_SECRET_ID
      export TENCENTCLOUD_SECRET_KEY=YOUR_SECRET_KEY

      Adding Container Monitoring Data Collection to Prometheus Instances

      1. Create a new Terraform configuration file: Create a new directory and a file named main.tf in the directory. The following shows the configuration:
      #Specifying Provider Configuration Information
      
      terraform {
  required_providers {
    tencentcloud = {
      source = "tencentcloudstack/tencentcloud"
    }
  }
}
      #Prometheus Managing Cloud Monitoring Integration
      
      #Prometheus Management of Container Clusters (Collection Containers)
      
      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" #ID of the cluster that needs to be associated
          enable_external = false
        }
      }
      Note:
      To create the Integration Center component of a Prometheus instance, the corresponding fields must be configured as follows:
      instance_id: (Required, string, ForceNew) Instance ID.
      agents: (Required, list) List of agents.
      cluster_id: (Required, string) Identifier for the cluster ID.
      region: (Required, string) Region restrictions.
      enable_external: (Required, Bool) Whether to enable public network CLB.
      cluster_type: (Required, string) Cluster type.
      For more details about parameters, see Detailed Parameters. You can also see Tencent Cloud Provider on Github and Terraform Tencent Cloud Provider.
      2. To initialize the Terraform runtime environment, run the following command:
      terraform init
      Expected output:
      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. To generate a resource plan, run the following command:
        terraform plan
      Expected output:
      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. To create component integration of the Integration Center, run the following command:
         terraform apply
      Expected output:
      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...
      Instance content...
      
      Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

      Viewing the Status of the Prometheus Instance

      Log in to the TCOP, and choose Managed Service for Prometheus from the left-hand navigation bar. Existing instances are displayed in the Prometheus instance list.

      Deleting the Component Integration in the Prometheus Instance Integration Center

      To terminate the resources, run the following command:
      terraform destroy
      Expected output:
      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:
      Instance content...
      
      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.
      Note:
      If Destroy complete! Resources: (numbers of existing instances) destroyed. is displayed, the instance has been deleted.
