GCP-Demo

GCP Cloud SDK 연동하여 GCP에 Computer Instance를 조작 및 관리하는 데모 프로젝트 입니다.

실행 방법

해당 데모 프로젝트 연동 및 테스트를 위해서는 SDK 설치 및 SDK 사용 인증 및 권한 부여가 필요합니다.

Computer Instance Test

public Compute createCompute(String applicationName) throws GeneralSecurityException, IOException {
    log.info("================== GCP Compute Build ==================");

    httpTransport = GoogleNetHttpTransport.newTrustedTransport();
    GoogleCredentials credential = GoogleCredentials.getApplicationDefault();
    HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(credential);

    return new Compute.Builder(httpTransport, JSON_FACTORY, requestInitializer)
            .setApplicationName(applicationName)
            .build();

Network Test

    log.info("================== GCP networkInterfaceConfig ==================");
    NetworkInterface networkInterface = new NetworkInterface();
    String networkSelfLink = networkList(compute).getItems()
            .stream()
            .map(Network::getSelfLink)
            .collect(Collectors.joining());

    networkInterface.setNetwork(networkSelfLink);

Firewall Test

 public FirewallConfigure config() throws IOException {

    Firewall firewall = new Firewall();
    List<String> sourceRanges = new ArrayList<>();
    List<String> targetTags = new ArrayList<>();
    sourceRanges.add("0.0.0.0/0");
    firewall.setName("default-allow-mysql");
    // firewall.setNetwork();
    // 우선순위 0~65535 미지정 1000 기본값, 암묵적으로 65535 사용으로 충돌방지 권장
    firewall.setPriority(65535);
    // 소스 범위 CIDR 형태로 사용 IPv4 만 지원 0.0.0.0/0
    firewall.setSourceRanges(sourceRanges);
    // 프로토콜 및 포트 설정
    firewall.setAllowed(allowedConfig("tcp", new String[]{"3306"}));
    firewall.setDescription("mysql allow");
    // 방화벽 적용 타겟 설정
    targetTags.add("test");
