Steps to Create Lambda

• Create Role

# Declare role-name
role_name="lambda-allow-basic"    
# Read the ./allow-role-policy.json.
policy=$(cat ./allow-role-policy.json | jq)
# Create the AWS-IAM role with the name lambda-ex and the above read-in policy. role-name and policy can be customized.
aws iam create-role --role-name $(echo "$role_name") --assume-role-policy-document $policy  

• Zip the index.js

zip index.zip index.js

• Create lambda

# Declare function-name & runtime
func_name="this-is-test-lambda"
runtime="nodejs12.x"
# Creae lambda with the func_name. --role ARN must be changed with the one created from the first step.  
aws lambda create-function --function-name $(echo "$func_name") --zip-file fileb://index.zip --handler index.handler --runtime $(echo "$runtime") --role arn:aws:iam::221262875767:role/lambda-allow-basic
