Enterprise Distributed Application Service:Install and configure Terraform

Procedure

1. Download the appropriate package for your operating system from the Terraform.

2. Extract the package to /usr/local/bin.

3. Run terraform to verify the installation.

   You should see output similar to this:

   username:~$ terraform
   Usage: terraform [-version] [-help] <command> [args]

4. Create a RAM user for better security.

   1. Log on to the Resource Access Management (RAM) console by using an Alibaba Cloud account.

   2. Create a RAM user named Terraform and create an AccessKey pair. For more information, see Create a RAM user.

   3. Grant permissions to the RAM user. In this example, grant AliyunEDASFullAccess and AliyunVPCFullAccess to the Terraform user. For more information, see Grant permissions to a RAM user.

5. Create a test directory.

   Each Terraform project needs its own working directory. Create a test directory named terraform-test:

   [user@test bin]#mkdir terraform-test

6. Navigate to the terraform-test directory.

   [user@test bin]#cd terraform-test
   [user@test terraform-test]#

7. Create configuration files.

   Terraform reads all *.tf and *.tfvars files in the directory. You can organize your configuration across multiple files:

   provider.tf           -- used to configure providers
   terraform.tfvars      -- used to configure the variables that are required to configure providers
   varable.tf            -- used to configure universal variables
   resource.tf           -- used to define resources
   data.tf               -- used to define package files
   output.tf             -- used to configure outputs

   For example, create provider.tf with your credentials:

   [user@test terraform-test]# vim provider.tf
   provider "alicloud" {
       region      = "cn-beijing"
       access_key  = "LTA**********NO2"
       secret_key  = "MOk8x0*********************wwff"
   }

   For more information about the configuration, see alicloud_edas_application.

8. Initialize the working directory.

   [user@test terraform-test]#terraform init
   
   
   Initializing provider plugins...
   - Checking for available provider plugins on https://releases.hashicorp.com...
   - Downloading plugin for provider "alicloud" (1.25.0)...
   
   
   
   
   The following providers do not have any version constraints in configuration,
   so the latest version was installed.
   
   
   To prevent automatic upgrades to new major versions that may contain breaking
   changes, it is recommended to add version = "..." constraints to the
   corresponding provider blocks in configuration, with the constraint strings
   suggested below.
   
   
   * provider.alicloud: version = "~> 1.25"
   
   
   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.                        

   Important

   You must run terraform init after creating a working directory and configuration files.
