Introduction :-

Remember the last time you tried to share a bunch of photos with a friend? Most likely, you zipped them into one file, right? Creating a zip file for AWS Lambda layers is somewhat similar but plays a crucial role in managing and deploying your serverless applications efficiently. Whether you’re a seasoned developer or just starting out, mastering this skill will make your life a whole lot easier. So, buckle up as we demystify the process together, step by friendly step.

• Open a command prompt or terminal window and Create a new directory for your layer zip files, and navigate into it:

mkdir lambda-layer
cd lambda-layer

• Create a requirements.txt file within the folder with following contents:

requests
boto3

This file specifies the dependencies required by the requests module.

• Install the dependencies into a site-packages directory within the layer:

pip install -r requirements.txt -t python/lib/python3.10/site-packages/

This command installs the requests module and its dependencies into a site-packages directory within the layer. You can specify a different version of Python by changing the path to the python directory.

• Zip the contents of the layer directory:

zip -r lambda-layer.zip . -x requirements.txt

This command creates a zip file containing the contents of the layer directory and excludes requirements.txt

• upload the created zip files into your lambda layer and create a layer in your aws account.

Conclusion :-

And just like that, you’re all set! Creating zip files for Lambda layers doesn’t have to be a headache. By following these simple steps, you can ensure your layers are perfectly packaged, every single time. Now, as you go about implementing this in your projects, remember to experiment and find what works best for you. Each project might require a slightly different approach, but with the basics under your belt, you’re more than ready to tackle them.
