Creating a deployment package for lambda functions.

To create a Lambda function, you first create a lambda function deployment package, a .zip file consisting of your code and any dependencies. generate_lambda_package.sh can be used to generate a deployment package.

USAGE:

$ cd <scripts_dir>
$ ./generate_lambda_package.sh -s=<SOURCE_PACKAGE_RELATIVE_PATH> -n=<LAMBDA_FUNCTION_PACKAGE_NAME> -b=<BUILD> -v=<PYTHON_VERSION> -o=<ORIGINAL_FILES>

OPTIONS:

• -s (--source): The relative path to the directory containing the lambda function. Note: Make sure that the directory contains a python file with the name lambda_function.py which contains the lambda function code.
• -n (--name): The name of the package that needs to be created.
• -b (--build) (optional): A boolean indicating whether the package needs to be built from scratch. By default, the package will leave out the dependencies and copy over only the lambda function. Set this to true to re-create all the dependencies. The dependent packages are generated based on the requirements.txt file present in the source directory.
• -v (--python_version) (optional): The python version to be used while installing the dependent packages. Defaults to python 2.7.0.
• -o (--keep_original) (optional): A boolean indicating whether the original package folder to be stored. By default, the original package folder will be removed and only zip of original folder is saved. Set this to true to keep original folder.

IMPORTANT NOTES:

• Currently, the packaging script have support for python 2.7.0, 3.5.0, 3.6.0 & 3.7.0.
