Build out a Kubernetes Cluster in an AWS VPC with Cloud Development Kit!

To Update kubeconfig:

aws eks update-kubeconfig --name custom-eks-cluster

Architecture

Requirements

• AWS CDK installed
• AWS CLI installed
• Run aws configure to configure access keys

AWS CDK Procedure

Create a virtualenv on MacOS and Linux:

$ python3 -m venv .venv

After the init process completes and the virtualenv is created, you can use the following step to activate your virtualenv.

$ source .venv/bin/activate

Once the virtualenv is activated, you can install the required dependencies.

$ pip install -r requirements.txt

At this point you can now synthesize the CloudFormation template for this code.

$ cdk synth

Deploy the IaaC code with:

$ cdk deploy

Useful commands

• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation

Enjoy!
