Hi@Abhishek,

You want to upload your zip file from s3 bucket to aws lambda function, for that you can use the bellow syntax.

To create one lambda function.

$ aws lambda create-function 
--function-name "awslambdausingcli" 
--runtime "pthon3.6" 
--role "arn:aws:iam::625297745038:role/lambdaapipolicy" 
--handler "awscli.handler" 
--timeout 5 
--memory-size 256 
--zip-file "fileb://awscli.zip"

To update that lambda function.

$ aws lambda
update-function-code
--function-name <value>
[--zip-file <value>]
[--s3-bucket <value>]
[--s3-key <value>]
[--s3-object-version <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Try with this once.

But as I already described that each time file name get change. So I don't want hard code the file name. That is why want to use *.zip. Will this solution work? I don't think so. Kindly suggest.

If you don't want to replace file name, then remove previous file and call the function with the same file name.
