How can I create an AWS Lambda function using the AWS CLI?

Question

I am trying to create an AWS Lambda function using the command

aws lambda create-function \\
  --function-name foo\\
  --runtime nodejs\\
  --role lambda_basic_e         


        

Answer 1

On mac I had to use absolute path, but added to the prefix there are actually 3 slashes.

Prefix:

fileb://

Path

/Users/myuser/Apps/folder/zips/file.zip

Complete

fileb:///Users/myuser/Apps/folder/zips/file.zip

Answer 2

You have an extra colon ':' in the file spec.

$ aws lambda create-function --function-name foo --runtime nodejs --role lambda_basic_execution --handler asdf --zip-file "fileb:://boom.zip"

--zip-file must be a file with the fileb:// prefix.
Example usage:  --zip-file fileb://path/to/file.zip

$ aws lambda create-function --function-name foo --runtime nodejs --role lambda_basic_execution --handler asdf --zip-file "fileb://boom.zip"

Error parsing parameter '--zip-file': Unable to load paramfile fileb://boom.zip: [Errno 2] No such file or directory: 'boom.zip'

Answer 3

I've had the same issue on Ubuntu 18.04 and what did the trick was enclosing both the name of the function and the fileb:/// with double " quotes.

aws lambda update-function-code --function-name "FUNCTION" --zip-file "fileb:///an/absolute/path/to/your/lambda/FUNCTION.zip"
