I'm deploying a springboot application with spring-cloud-stream and binder for AWS Kinesis. The application works fine when is deployed on aws elastic beanstalk if the beanstalk is configured with public ip. When we set beanstalk with private ip, the application throws warnings at deploy because is unable to get some metadata from aws.
Why is trying to get these resorurces? There are some workaround to remove this warnings?
These are warnings thrown when application is deployed and no public ip is set on ec2.

To view instance metadata, you can only use the link-local address of 169.254. 169.254 to access. Requests to the metadata via the URI are free, so there are no additional charges from AWS. Using the curl tool on Linux or the PowerShell cmdlet Invoke-WebRequest on Windows, you will first create your token.
Instance metadata is data about your instance that you can use to configure or manage the running instance. Instance metadata is divided into categories, for example, host name, events, and security groups. You can also use instance metadata to access user data that you specified when launching your instance.
Can be accessed using the URL http://169.254.169.254/latest/dynamic/ Note: Although you can only access instance metadata and user data from within the instance itself, the data is not protected by cryptographic methods. Anyone who can access the instance can view its metadata.
This exception is happening within the Amazon SDK. If you simply don't like the stacktrace, you can update your logging configuration to only report at the ERROR level for com.amazonaws. If you don't need any of the instance data for the EC2 instance you are running on, you can add or update the annotation
@EnableAutoConfiguration(exclude = {ContextInstanceDataAutoConfiguration.class})
on one of your configuration classes.
