I used to download them locally, zip them, upload them into S3 when their sizes were big, and then create a version. This process takes a long time, and chances are high that you will make a defective layer when you’re using Windows or Mac because of some layers that compile binaries when you download them. I wrote an article back in 2019 on how to do that with the help of Docker, and it still gets read, which triggers the need to create a new, simple, and extremely fast way to use this amazing feature: Lambda Layers. I will walk you through what it does and how you can have it in your account. Please note that this process is only (currently) for Python3.8. This script consists of 3 main steps: create a new layer, update the existing one, and read what’s inside your latest layer version. Because of the struggle I mentioned at first, this process is time-consuming when it comes to the manual, traditional way.
