Example Lambda Function running Python and X-ray using the https://github.com/racker/fleece/

Build dependencie package

1. Run the following commands:

mkdir .vendor
pip install -r requirements.txt -t .vendor
serverless deploy

2. Got to the AWS Lambda Console and enable active tracing for the function.

3. Make sure your lambda function has permission to access GetUser in IAM and use X-Ray by creating a role with the following policy. If you use serverless framework to deploy, that step is not necessary since everything is set in the serverless.yml file

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "logs:CreateLogStream"
                "xray:PutTraceSegments",
                "xray:PutTelemetryRecords",
                "logs:PutLogEvents"
                "iam:Get*"
            ],
            "Resource": [
                "*"
            ],
            "Effect": "Allow"
        }
    ]
}

4. Invoke your function and text X-Ray with Python

serverless invoke -f hello -l
