AWS lambda func

setup

create role

aws iam create-role --role-name lambda-ex --assume-role-policy-document '{"Version": "2012-10-17","Statement": [{ "Effect": "Allow", "Principal": {"Service": "lambda.amazonaws.com"}, "Action": "sts:AssumeRole"}]}'

create file in the root directory of your main.go called trust-policy.json

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "lambda.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

point the aws-cli to the trust policy file just created

aws iam create-role --role-name lambda-ex --assume-role-policy-document file://trust-policy.json

configure policy/role

aws iam attach-role-policy --role-name lambda-ex --policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole

build the go binary (if trouble, run 'go mod tidy')

go build main.go

zip the built "main" into a zip called function.zip

zip function.zip main

create the lambda function with aws cli (replace 123456789012 with your aws account id)

aws lambda create-function --function-name test-lambda-go-func --zip-file fileb://function.zip --handler main --runtime go1.x --role arn:aws:iam::123456789012:role/lambda-ex

invoke the lambda function

aws lambda invoke --function-name test-lambda-go-func --cli-binary-format raw-in-base64-out --payload '{"What is your name?": "Jim", "How old are you?": 33}' output.txt
