본 API 가 삭제 되었기 때문에 그냥 아래와 같이 단순하게 구성해 보았습니다.

@Service
@Log4j2
@RequiredArgsConstructor
public class Ec2Service {

  public ResponseEntity<String> describeInstanceTypes() {
    ProcessBuilder builder = new ProcessBuilder();
    String instances = "{}";

    try {
      builder.command("bash", "-c", "aws ec2 describe-instance-types");
      Process process = builder.start();

      instances = new BufferedReader(
        new InputStreamReader(process.getInputStream(), StandardCharsets.UTF_8)).lines()
        .collect(Collectors.joining("\n"));

      int exitCode = process.waitFor();

      JSONObject jsonObject = new JSONObject(instances);
      JSONArray jsonArray = jsonObject.getJSONArray("InstanceTypes");
      JSONArray sortedJsonArray = new JSONArray();
      List list = new ArrayList();

      for(int i = 0; i < jsonArray.length(); i++) {
        list.add(jsonArray.getJSONObject(i));
      }

      Collections.sort(list, new Comparator<JSONObject>() {

        @Override
        public int compare(JSONObject a, JSONObject b) {
          String source = new String();
          String target = new String();

          try {
            source = (String)a.get("InstanceType");
            target = (String)b.get("InstanceType");
          } catch(Exception e) {
          }

          return source.compareTo(target);
        }
      });

      for(int i = 0; i < jsonArray.length(); i++) {
        sortedJsonArray.put(list.get(i));
      }

      instances = "{\"InstanceTypes\": " +sortedJsonArray.toString()+ "}";
    } catch(Exception e) {
      e.printStackTrace();
    }

    return ResponseEntity.ok(instances);
  }
}

코드 자체는 AWS CLI 를 ProcessBuilder 를 이용해서 외부 파일을 실행 시켜 데이터를 받아와서 처리 하는 내용입니다.

AWS CLI 로 데이터를 가져 오게 되면 정렬이 안된 상태로 데이터가 넘어 와서 별도 sort 기능 구현이 필요 합니다.

그냥 CLI 에서도 JSON Sort 옵션 하나 넣어 주면 좋았을 걸 아쉽더라고요.

근데 왜 이 API 를 없앴는지 차암....

1.x 에서 삭제 되어서 2.x 로 변경해서 사용 하시면 됩니다.

    Ec2Client ec2Client = Ec2Client.builder().build();
    DescribeInstanceTypesRequest request = DescribeInstanceTypesRequest.builder()
      .maxResults(100)
      .build();

    DescribeInstanceTypesResponse response = ec2Client.describeInstanceTypes(request);
    log.debug("{}", response.instanceTypes());

한번에 100개 씩 밖에 못 가져 오기 때문에 nextToken 으로 끝까지 요청 하셔야 합니다.

개발 진행을 하다 보면 대 부분 레퍼런스 문서와 API 문서를 안 볼 수가 없습니다.

더군다나 제공 하는 모든 API 를 다 기억 할 수도 없구요.

그래서 그냥 한 눈에 보기 편하게 모아 두었습니다.

AWS에서 ELB 사용 시 instance 를 넣고 빼고 하는 CLI 예제 입니다.

제가 필요해서 그냥 기록해 봅니다.

[참조문서]

http://docs.aws.amazon.com/cli/latest/reference/elb/index.html

[AWS CLI 구성]

[AWS Configure]

이 작업은 aws cli를 사용하기 위한 access key 와 secret access key 그리고 region 등록을 하게 됩니다.

설정을 완료 하게 되면 user home 아래 .aws/config 파일이 생성 됩니다.

- 여기서 주의 하실 점은 region 정보에 tokyo 에 있다고 tokyo 로 하시면 못찾습니다. 위 예시와 같이 작성해 주셔야 합니다.
