Creating an AWS Lambda function from the AWS CLI

To create an AWS Lambda function from the AWS CLI, you can use the aws lambda create-function command. Here is an example of how you might use this command to create a new Lambda function:

aws lambda create-function \ --function-name MyFunction \ --runtime python3.8 \ --role arn:aws:iam::123456789012:role/MyIAMRole \ --handler index.handler \ --zip-file fileb://function.zip

This will create a new Lambda function named MyFunction that runs a Python 3.8 runtime and has the specified IAM role. The function’s code is contained in the function.zip file, which is uploaded using the --zip-file parameter. The function’s handler is specified using the --handler parameter, which specifies the file name and function name separated by a period (e.g., index.handler).

For more information, you can refer to the AWS Lambda documentation on creating a function.
