]Configuring Terraform for Linode
Linode用のprovider.tfを作成
terraform {
required_providers {
linode = {
source = "linode/linode"
version = "~> 2.0.0"
}
}
}
provider "linode" {
token = "LINODE_API_TOKEN"
}
API_TOKENはLinode management consoleで作成する。
プロジェクトフォルダ内でterraformを初期化する。
terraform init初期化成功すると下記のようなメッセージが表示される。
Initializing the backend...
Initializing provider plugins...
- Finding linode/linode versions matching "~> 2.0.0"...
- Installing linode/linode v2.0.0...
- Installed linode/linode v2.0.0 (signed by a HashiCorp partner, key ID F4E6BBD0EA4FE463)
Partner and community providers are signed by their developers.
If you'd like to know more about provider signing, you can read about it here:
https://www.terraform.io/docs/cli/plugins/signing.html
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
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.Creating Linodes by Terraform
