python-layer 1.2.2

Manage aws layers

Python-layer

The python-layer is a script inspired from python-lambda that can help managing aws layers. There are 5 available commands with options.

Requirements

• Python 3
• GNU Linux

Installation

You can create a new virtual environment on your computer and then install python-layer via pypi. pip install python-layer

Getting Started

The script searches in a directory for the requirements.txt file and creates a zip with all the dependencies. If there are .py files, they are included in the zip.

To create a new layer: layer build path/to/mydir

Here we suppose that mydir has at least the requirements file.

To deploy the layer to aws: layer deploy path/to/zip -d myshortdescription --runtime python3.7

To deploy the layer to aws to a specific region layer deploy path/to/zip -r region_name

To deploy the layer to aws to a specific region and to a specific profile (e.g. dev profile) layer deploy path/to/zip -p dev_profile -r region_name

To list the available layers: layer list

To list the available layers from a specific region: layer list -r region_name

To list the available layers from a specific region and from a specific profile (e.g. dev profile): layer list -r region_name -p dev_profile

To set a layer to a lambda function (appends the latest version of the layer): layer set mylayer mylambda

To set a layer to a lambda function (appends the latest version of the layer) to a specific region: layer set mylayer mylambda -r region_name

To set a layer to a lambda function (appends the latest version of the layer) to a specific region and to a specific profile: layer set mylayer mylambda -p dev_profile -r region_name

To set a list of layers: layer set mylayer1,mylayer2 mylambda

To set a list of layers replacing the older ones : layer set mylayer1,mylayer2 mylambda -d

To download a layer layer download mylayer

To download a layer from a specific region: layer download mylayer -v version_number -r region_name

To download a layer from a specific region and from a specific profile (e.g. dev profile): layer download mylayer -v version_number -r region_name -p dev_profile

Notes

• Currently the script uses the credentials from the ~/.aws/config file.
