provider.tf

provider.tf 将创建所需的提供程序。

terraform {
   required_providers {
      ibm = {
         source = "IBM-Cloud/ibm"
         version = "1.38.2"
      }
   }
}

variables.tf

variables.tf 存储 Terraform 在运行时所需的密码或其他值。

variable "instance_id" {
   type        = string
   default     = "235b109c-0a2c-438b-8758-1a4b9db044db"
   description = "Event Notifications service instanceId."
}

variable "destination_name" {
   type        = string
   default     = "Smart Home Android app"
   description = "Destination name."
}

variable "destination_description" {
   type        = string
   default     = "Smart House device status"
   description = "Description for the destination."
}

variable "webhook_type" {
   default     = "webhook"
   type        = string
   description = "Type of the destination"
}

variable "webhook_verb" {
   default     = "POST"
   type        = string
   description = "Type of verb fro the destination"
}

variable "webhook_URL" {
   type        = string
   description = "URL of the webhook"
   default     = "https://hello.demo.com/hello"
}

其余文件将声明要部署的资源。

instance.tf

instance.tf 供应 Event Notifications 实例。

resource "ibm_resource_instance" "terraform_demo" {
   plan     = "lite"
   location = "us-south"
   name     = "terraform_demo"
   service  = "event-notifications"
}

destinations.tf

destinations.tf 使用 Event Notifications 来创建目标。

resource "ibm_en_destination" "destination1" {
   type          = var.webhook_type
   name          = var.destination_name
   description   = var.destination_description
   instance_guid = ibm_resource_instance.terraform_demo.guid
   config {
      params {
         url  = var.webhook_URL
         verb = var.webhook_verb
         custom_headers = {
           "authorization" = "secure"
         }
         sensitive_headers = ["authorization"]
      }
   }
}

topics.tf

topics.tf 使用 Event Notifications 来创建主题。

resource "ibm_en_topic" "topic1" {
   instance_guid = ibm_resource_instance.terraform_demo.guid
   description   = "Check the status of front door"
   name          = "Front Door Status"
}

subscriptions.tf

subscriptions.tf 使用 Event Notifications 来创建预订。

resource "ibm_en_subscription" "subscription1" {
   instance_guid  = ibm_resource_instance.terraform_demo.guid
   name           = "Android app Subscription"
   description    = "Subscribe to Android app"
   topic_id       = ibm_en_topic.topic1.topic_id
   destination_id = ibm_en_destination.destination1.destination_id
   attributes {
      add_notification_payload = true
      signing_enabled          = true
   }
}

Terraform启动

Terraform init 命令会准备环境，确保目录配置正确：

bash-5.1# terraform init

Initializing the backend...

Initializing provider plugins...
- Reusing previous version of ibm-cloud/ibm from the dependency lock file
- Using previously-installed ibm-cloud/ibm v1.38.2

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.

Terraform计划

Terraform计划命令会将声明的资源与状态文件进行比较，以打印要创建、更改或删除的资源。 此步骤向您显示 main.tf 文件的影响。

bash-5.1# terraform plan

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:

   # ibm_en_destination.destination1 will be created
   + resource "ibm_en_destination" "destination1" {
