What does CDK Bootstrap do

In this post, we will give you information about What does CDK Bootstrap do. Here we will give you detail about What does CDK Bootstrap do And how to use it also give you a demo for it if it is necessary.

Bootstrapping is the process of provisioning resources for the AWS CDK before you can deploy AWS CDK apps into an AWS environment. (An AWS environment is a combination of an AWS account and Region).

These resources include an Amazon S3 bucket for storing files and IAM roles that grant permissions needed to perform deployments.

What is CDK bootstrap?

CDK bootstrap is a command we can access using the CDK CLI.

npx aws-cdk bootstrap

The cdk bootstrap command provisions a CloudFormation stack called CDKToolkit. This CloudFormation stack is specific to the environment (region and account) our CDK stack is configured for.

Every CDK application belongs to a specific environment.

An environment consists of an account number and a region, where the CDK app is going to be deployed.

We set the environment for a CDK project when instantiating a CDK stack:

const app = new cdk.App();

const myStack = new MyCdkStack(app, 'your-cdk-stack', {
  stackName: `your-cdk-stack`,
  //set the environment
  env: {
    region: process.env.CDK_DEFAULT_REGION,
    account: process.env.CDK_DEFAULT_ACCOUNT,

How to bootstrap

Bootstrapping is the deployment of an AWS CloudFormation template to a specific AWS environment (account and Region). The bootstrapping template accepts parameters that customize some aspects of the bootstrapped resources (see Customizing bootstrapping). Thus, you can bootstrap in one of two ways.

  • Use the AWS CDK Toolkit’s cdk bootstrap command. This is the simplest method and works well if you have only a few environments to bootstrap.
  • Deploy the template provided by the AWS CDK Toolkit using another AWS CloudFormation deployment tool. This lets you use AWS CloudFormation StackSets or AWS Control Tower and also the AWS CloudFormation console or the AWS CLI. You can make small modifications to the template before deployment. This approach is more flexible and is suitable for large-scale deployments.

It is not an error to bootstrap an environment more than once. If an environment you bootstrap has already been bootstrapped, its bootstrap stack will be upgraded if necessary. Otherwise, nothing happens.
