i have airbyte set up in abctl in an ec2, how do i use the ec2 instance profile in the aws s3 destination connector? its giving me No identity could be resolved from the chain

To use the EC2 instance profile for authentication in the AWS S3 destination connector with Airbyte (deployed via abctl on EC2), you should leave the Access Key ID, Secret Access Key, and Role ARN fields empty in the S3 destination connector configuration. When these fields are not provided, Airbyte will attempt to use the instance profile attached to the EC2 instance for authentication. Key steps: 1. Attach an IAM Role (instance profile) to your EC2 instance with the necessary S3 permissions. The policy should allow actions like

s3:PutObject

,

s3:GetObject

,

s3:DeleteObject

,

s3:ListBucket

, etc., on your target bucket. Example policy:

json     {         "Version": "2012-10-17",         "Statement": [           {             "Effect": "Allow",             "Action": [               "s3:PutObject",               "s3:GetObject",               "s3:DeleteObject",               "s3:PutObjectAcl",               "s3:ListBucket",               "s3:ListBucketMultipartUploads",               "s3:AbortMultipartUpload",               "s3:GetBucketLocation"             ],             "Resource": [               "arn:aws:s3:::YOUR_BUCKET_NAME/*",               "arn:aws:s3:::YOUR_BUCKET_NAME"             ]           }         ]       }

[S3 destination setup](https://docs.airbyte.com/integrations/destinations/s3) 2. In the Airbyte S3 destination connector configuration: - Leave Access Key ID, Secret Access Key, and Role ARN blank. - Fill in the required fields: S3 Bucket Name, S3 Bucket Path, and S3 Bucket Region. 3. Verify connectivity: Make sure your EC2 instance can access the S3 bucket (networking, VPC, and security group settings). 4. Test the connection using the "Check connection" tool in the Airbyte UI. If you see the error "No identity could be resolved from the chain," it usually means: - The EC2 instance does not have an instance profile attached, or - The instance profile does not have the correct permissions, or - The Airbyte connector is not running with the correct environment to pick up the instance profile. Note: The documentation confirms that if you omit the credentials, Airbyte will rely on the instance profile for authentication ([source](https://docs.airbyte.com/integrations/destinations/s3#step-2-set-up-the-s3-destination-connector-in-airbyte)). If you have confirmed the above and still encounter issues, double-check that your Airbyte deployment is not overriding AWS credential environment variables and that the IAM role is properly attached to the EC2 instance. If you need more details on the required IAM policy, see the example in the documentation: [S3 destination setup](https://docs.airbyte.com/integrations/destinations/s3#step-2-set-up-the-s3-destination-connector-in-airbyte).

@kapa.ai How do i confirm if this is the issue? The Airbyte connector is not running with the correct environment to pick up the instance profile.
