java - 如何设置不需要凭据的 Localstack 容器？

问题描述

我有以下代码片段，它应该在 AWS Lambda 函数中运行：

AWSSecretsManager client = AWSSecretsManagerClientBuilder.standard().withRegion(AWS_REGION).build();
GetSecretValueRequest getSecretValueRequest = new GetSecretValueRequest().withSecretId(SECRET_NAME);
GetSecretValueResult secretValue = client.getSecretValue(getSecretValueRequest);

由于 lambda 函数将在与秘密管理器相同的 VPC 中运行，因此我不必为其提供凭据 ( AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)。

我使用 Localstack 和 Testcontainers 进行集成测试，并在测试设置中设置秘密，如下所示：

AWSSecretsManager secretsManager = AWSSecretsManagerClientBuilder.standard()
        .withEndpointConfiguration(secretsmanager.getEndpointConfiguration(SECRETSMANAGER))
        .withCredentials(secretsmanager.getDefaultCredentialsProvider())
        .build();
String secretString = "{'engine':'mysql','port':" + mysql.getMappedPort(3306) + ",'host':'" + mysql.getContainerIpAddress() + "'}";
CreateSecretRequest request = new CreateSecretRequest().withName("aurora")
        .withSecretString(secretString)
        .withRequestCredentialsProvider(secretsmanager.getDefaultCredentialsProvider());
secretsManager.createSecret(request);

现在测试因错误而崩溃：

com.amazonaws.services.secretsmanager.model.AWSSecretsManagerException: 
The security token included in the request is invalid. 
(Service: AWSSecretsManager; 
Status Code: 400; Error Code: 
UnrecognizedClientException; 
Request ID: ...

这里也是测试中使用的localstack容器的定义：

@ClassRule
public static LocalStackContainer secretsmanager = new LocalStackContainer("0.10.4")
    .withServices(LocalStackContainer.Service.SECRETSMANAGER)
    .withEnv("DEFAULT_REGION", "eu-west-1")
    .withExposedPorts(4584);

如何将 LocalStackContainer 配置为在不进行任何凭据验证的情况下接受请求？

解决方案

假设您是一个合理的 java 开发人员，更喜欢 spring boot 测试和 junit5 而不是替代品，@DynamicPropertySource在这里可以很方便

private static final LocalStackContainer LOCALSTACK = ...;

@DynamicPropertySource
static void setCredentials(DynamicPropertyRegistry registry) {
    var credentials = LOCALSTACK.getDefaultCredentialsProvider().getCredentials();
    registry.add("cloud.aws.region.static", () -> "eu-central-1");
    registry.add("cloud.aws.credentials.access-key", () -> credentials.getAWSAccessKeyId());
    registry.add("cloud.aws.credentials.secret-key", () -> credentials.getAWSSecretKey());
    registry.add("cloud.aws.s3.endpoint", () -> LOCALSTACK.getEndpointOverride(S3));
}

另外请仔细检查您是否覆盖了您依赖的端点（在我的示例中为 s3），否则您可能会请求真正的 AWS API 而不是容器化的
