Writing your first template using AWS CDK and Python
We will begin by installing the prerequisites for CDK. Even though we are going to write our code in Python, we still need to install nodejs. Once this is done, we can install CDK:
$ npm install -g aws-cdk
After this, we need to check whether everything is correct by printing out the version of CDK:
$ cdk --version
Installing CDK doesn't mean we have all the construct libraries.
First, we need to initialize the environment:
$ mkdir app && cd app $ cdk init app --profile personal --language=python $ source .env/bin/activate $ pip install -r requirements.txt
Then, we install the core components of CDK:
$ pip install --upgrade aws-cdk.core
The cdk init phrase will create all the files, so we can start developing our infrastructure right away.
Preparing constructs
We will build the same infrastructure that we built in Chapter 2, Advanced Template Development. Our infrastructure will consist...
