Managing Python Dependencies in Serverless

Prerequisites

In order to run the following commands, you need to have a Ubuntu (or any other Debian-based) work environment up and running!

STEPS

1. Upgrade pip and virtaulenv
   Run the following commands:sudo -H pip3 install --upgrade pip sudo -H pip3 install virtualenv
   • Then we need to create a virtaulenv

   python3 -m venv your_venv

   • Now we have to activate it.

   source your_venv/bin/activate

   • Install all the dependencies specified in the requirements.txt file

   pip install -r requirements.txt



2. Install the Serverless Python Requirements Pluginsls plugin install -n serverless-python-requirements This will automagically add the plugin to the serverless.yml fileplugins: - serverless-python-requirements
   • To make the package of python dependencies, run

   sls package

   • Now deploy it to AWS

   sls deploy All okay? Boom!
