  mkdir cdk-pycon-eks
  cd cdk-pycon-eks
  cdk init app --language=python
  

• Copy and override requirements.txt to your work folder

• Now open a Terminal in your IDE and create env and install the dependencies

pip install -r requirements.txt

• Open your IDE as you like:

  code .
  OR
  pycharm .
  

Now you can start coding your infrastructure.

Coding

• Copy and override app.py to your work folder ./app.py in your IDE.
• Copy and override cdk_pycon_eks_stack.py to your work folder ./cdk_pycon_eks/cdk_pycon_flask_eks.py in your IDE.

Deploy

• Deploy the stack in Terminal:

cdk deploy

Enter "y" while deploying ask to confirm.
You can observe via AWS Console -> CloudFormation to see the CloudFormation template is being deploy.

Clean up

Delete whole stack in one command. It is very easy and clean.

cdk destroy

You can check the CloudFormation in AWS Console -> CloudFormation to confirm the delete completed or find the cause if there is fail.
