Terraform을 이용하여 Splunk Observability의 detector 생성

https://registry.terraform.io/providers/splunk-terraform/signalfx/latest/docs/resources/detector

Terraform Registry

 

위 예제를 참고하여 실습을 진행.

example 소스에 빨간색 박스 관련 내용을 추가해야 한다.

 

최종 테라폼 파일 (detector.tf)

  tags        = ["app-backend", "staging"]

  # Note that if you use these features, you must use a user's
  # admin key to authenticate the provider, lest Terraform not be able
  # to modify the detector in the future!

detector.tf 파일이 있는 경로에서 아래 명령을 차례로 수행하면 code로 작성된 detector가 생성된 것을 확인할 수 있다.

terraform init
terraform plan
terraform apply
