Bash 스크립트 AWS CLI 와 함께 사용하는 Amazon EC2 예제

다음 코드 예제에서는 Amazon 에서 Bash 스크립트 AWS Command Line Interface 와 함께 를 사용하여 작업을 수행하고 일반적인 시나리오를 구현하는 방법을 보여줍니다EC2.

기본 사항은 서비스 내에서 필수 작업을 수행하는 방법을 보여주는 코드 예제입니다.

작업은 대규모 프로그램에서 발췌한 코드이며 컨텍스트에 맞춰 실행해야 합니다. 작업은 개별 서비스 함수를 직접적으로 호출하는 방법을 보여주며 관련 시나리오의 컨텍스트에 맞는 작업을 볼 수 있습니다.

각 예제에는 컨텍스트에서 코드를 설정하고 실행하는 방법에 대한 지침을 찾을 수 있는 전체 소스 코드에 대한 링크가 포함되어 있습니다.

기본 사항

다음 코드 예시는 다음과 같은 작업을 수행하는 방법을 보여줍니다.

  • 키 페어 및 보안 그룹을 생성합니다.

  • Amazon Machine Image(AMI)와 호환되는 인스턴스 유형을 선택한 다음 인스턴스를 생성합니다.

  • 인스턴스를 중지한 후 다시 시작합니다.

  • 인스턴스와 탄력적 IP 주소 연결.

  • 를 사용하여 인스턴스에 연결SSH한 다음 리소스를 정리합니다.
