Lambda: make it easier to specify a list of files and directories instead of a directory for code assets

[eladb]

Since #4473 has landed, which has support for richer .dockerignore patterns, there is no need for this anymore. This is very simply achieved by:

      code: lambda.Code.fromAsset(".", {exclude: ["**", "!index.py"]}),

You can consider adding this example somewhere if you wish, or just closing this outright.

Still think we should provide first class api for this

I don't know if this is related, but I'd like to also be able to upload a directory without zipping it. Is this feasible, already possible?

[eladb]

@melnikalex check out the s3-deployment module for that.

I just tried using this, at first it seemed to work fine, but I just realized that when I try to deploy, the latest version of my lambda is not detected.

I do some changes to the file, then run either cdk diff or cdk deploy and all I get are no changes, so I think the sourceHash is not being correctly generated...

A simple SHOULD workaround is passing a different source hash everytime, here is a dummy implementation since I don't want to use this forever or calculate the hash myself:

return new lambda.AssetCode(DIST_FOLDER, { exclude: ["**", `!${fileName}.js`], sourceHash: new Date().toISOString() });

then doing cdk diff does detect there is some changes, however when I run the lambda I only get the old code running...

EDIT: I can confirm this is happening, I just refactored my code to adhere to the old way of doing things (packaging an entire folder) and things are working as expected, looking forward to this feature though, mighty useful if you are using webpack and packaging lambdas into a single file

How do I whitelist a directory from exclusion?

Whitelisting a file by using "!index.py" works. However, whitelisting a directory is not working. I tried "!/dir/**", "!/dir", "!/dir/*", "!dir" but non of them are working.

@yogur

alright this worked for me

lambda.Code.fromAsset(".", {exclude: ['**', '!dir', '!dir/*']})

The exclude option is deprecated, is there a better alternative?

[zacyang]

The document is not even mention what is replacing it, just deprecate it....wat...

[ghost]

I've been using this heavily and also just noticed it's been deprecated... Is there an existing alternate or one in the works? Thanks!
