Spring Cloud AWS SQS fails to connect to service endpoint locally

Question

I'm trying to use Spring Cloud's AWS SQS in a project I'm working on. At this time, I'm only running the application locally on my dev machine. Thus, what I want is to connect to the SQS on AWS without having to deploy my app to an EC2 instance.

However, it seems like the AWS SDK used in Spring Cloud's AWS package will attempt to authenticate through metadata and wants to resolve 169.254.169.254/latest/meta-data/instance-id. Since I'm still the running the app locally, the endpoint cannot be resolved and an error is thrown:

2019-12-29 16:38:27.420  WARN 22462 --- [  restartedMain] com.amazonaws.util.EC2MetadataUtils      : Unable to retrieve the requested metadata (/latest/meta-data/instance-id). Failed to connect to service endpoint:

...

I've tried to explicitly supply an SQS endpoint in my bean, but it still attempts to connect to 169.254.169.254 resulting in the error above:

public AmazonSQSAsync sqsClient() {
   EndpointConfiguration endpointConfig = new AwsClientBuilder.EndpointConfiguration(
        "sqs.us-east-1.amazonaws.com",
        "us-east-1"
   );

   return AmazonSQSAsyncClientBuilder
                .standard()
                .withEndpointConfiguration(endpointConfig)
                .withCredentials(new AWSStaticCredentialsProvider(new DefaultAWSCredentialsProviderChain().getCredentials()))
                .build();
}

Although I'm not certain about this, I suspect that the error is occurring because I'm running the app locally on my dev machine and so it couldn't resolve to the endpoint. But I'm not entirely sure about this too because I'm running other AWS services in the same app using the AWS SDK and I don't have this error.

I've the following dependencies in my pom.xml and it appears that having any one of them will cause the error to occur. That's, I don't even have to create the beans to have that error. Adding these dependencies will immediately, for some reason, causes the SDK to attempt to resolve that endpoint and fail with that error.

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-aws</artifactId>
            <version>2.2.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-aws-messaging</artifactId>
            <version>2.2.1.RELEASE</version>
        </dependency>

What else should I do to fix the error that it failed to connect to service endpoint?

I have received below errors when running Spring Boot Project for AWS SNS

        }
)

Solution 2

I know many people have already explained what's issue and how to skip this error. But, all the above method didn't work for me. Finally after lot of search I set following aws configuration property and it worked for me.

cloud.aws.region.use-default-aws-region-chain=true
cloud.aws.stack.auto=false
cloud.aws.credentials.access-key=
cloud.aws.credentials.secret-key=
cloud.aws.region.auto=false
cloud.aws.region.static=
cloud.aws.stack=false

logging.level.com.amazonaws.util.EC2MetadataUtils=error
logging.level.com.amazonaws.internal.InstanceMetadataServiceResourceFetcher=error

Solution 3

When using the AWS Java SDK outside of an EC2 instance, you can disable loading credentials or regions from EC2 Metadata instance service with a System property or an Environment variable.

• System Property : com.amazonaws.sdk.disableEc2Metadata
• Environment variable : AWS_EC2_METADATA_DISABLED

However, you will still get a warning at application startup, it tells you the EC2Metadata is disabled by configuration : "EC2 Instance Metadata Service is disabled"

2020-03-27 18:10:42.483  WARN 71123 --- [main] com.amazonaws.util.EC2MetadataUtils      : Unable to retrieve the requested metadata (/latest/meta-data/instance-id). EC2 Instance Metadata Service is disabled

Solution 4

The following configuration worked for me:

cloud:
  aws:
    region:
      auto: false
      static: eu-west-1
      use-default-aws-region-chain: true
    stack: false
    stack.auto: false
logging:
  level:
    com:
      amazonaws:
        internal:
          InstanceMetadataServiceResourceFetcher: error
        util:
          EC2MetadataUtils: error

Solution 5

Fix the problem adding in the application.yaml file:

logging:
  level:
    com:
      amazonaws:
        util:
          EC2MetadataUtils: error

Is your SQS has only IAM based access ?

[Carven]

@SauravKumarSingh I don’t think so. I don’t remember creating the SQS queue to restrict only to IAM access unless that’s the default configuration.

[smac2020]

Use the Official AWS Java API over this 3rd party API to invoke AWS Services from within a Spring app. For starters, you will get support from the AWS Java SDK team.

[Carven]

I've just tried using 2.2.0.RELEASE but the same error is still occurring.

[Carven]

I already have cloud.aws.region.auto set to false and cloud.aws.region.static set to my region but it seems like it's still attempting to retrieve from the EC2 meta data and resulting in the error.

[nickolay.laptev]

These are the only options that influence on using meta data service. If they don’t work, then you have Spring bug. However this is basic functionality and there are many people who use it. From your question I don’t see you set these properties, the way how you build sqsClient is not the same as setting these options via property file.

[nickolay.laptev]

It's in fact Spring bug. I experience the same problem now. Adding "cloud.aws.stack.auto=false" can be a workaround, however there are many warnings generated

[Keith Bennett]

Was a solution ever found for this? I am experiencing the same issue and have documented it here: stackoverflow.com/questions/63271529/….

[Procrastinator]

Please add some explanation to your code so that it'd be easy to understand for others

Just added the parameters in IntelliJ run configuration and it works fine: logging.level.com.amazonaws.util.EC2MetadataUtils=error logging.level.com.amazonaws.internal.InstanceMetadataService‌​ResourceFetcher=erro‌​r
