nodejs14.x support

[larose]

Thank you very much for this project. It's been very useful to me.

I noticed that nodejs14.x isn't supported. How can I add it? I found these instructions in the readme:

By tarring the full filesystem in Lambda, uploading that to S3, and then piping into Docker to create a new image from scratch – then creating mock modules that will be required/included in place of the actual native modules that communicate with the real Lambda coordinating services. Only the native modules are mocked out – the actual parent JS/PY/Java runner files are left alone, so their behaviors don't need to be replicated (like the overriding of console.log, and custom defined properties like callbackWaitsForEmptyEventLoop)

I think I understand the main steps, but I won't have the permission to upload the filesystem snapshot to lambci's s3 bucket for example. How can external collaborators contribute a new image?

Is there someone with the right permissions who can look into this? It seems like this doesn't require much work, just someone with the right permissions.

It would be great to have Node.js 14.x support! @mhart @sanathkr @ndobryanskyy If you & the others are too busy to maintain, would it maybe make sense to get an AWS employee to manage this repo and keep it up to date?

AWS already provides prebuilt build images for local Lambda emulation via it's SAM CLI framework:

• https://hub.docker.com/r/amazon/aws-sam-cli-build-image-nodejs12.x
• https://hub.docker.com/r/amazon/aws-sam-cli-build-image-nodejs14.x

Source of this images can be found here: https://github.com/aws/aws-sam-cli/blob/develop/build-image-src/Dockerfile-nodejs14x

It's bittersweet since this project provided so much value in the early days of serverless development on AWS but I think this is the way forward from now on 😔

The problem is, other projects depend on this one. Namely, https://github.com/dherault/serverless-offline.

So I imagine package maintainers will have to update how they run a local Lambda Docker instance.

Agree, it's a general problem that AWS currently eats up (namely SAM and Amplify) a lot of space where third party serverless providers like Serverless Framework exist.
But the initiative to overtake or support community projects like this must come from big third-party serverless vendors, because AWS always builds its own tools rather than supporting community projects.

Unfortunately my bet in this war goes once more to AWS here because they have 1000x the resources than all vendors together, but would be happy to switch back to community projects in the future.

I've had luck using the amazon/aws-lambda-nodejs:14 image. Took a while to figure out which images were for which use cases, but I think that that is the best alternative for these images.
