cdk bootstrap

The target AWS environment to deploy the bootstrap stack to in the following format: aws://<account-id>/<region>.

Example: aws://123456789012/us-east-1

This argument can be provided multiple times in a single command to deploy the bootstrap stack to multiple environments.

By default, the CDK CLI will bootstrap all environments referenced in the CDK app or will determine an environment from default sources. This could be an environment specified using the --profile option, from environment variables, or default AWS CLI sources.

The name of the Amazon S3 bucket that will be used by the CDK CLI. This bucket will be created and must not currently exist.

Provide this option to override the default name of the Amazon S3 bucket.

When you use this option, you may have to customize synthesis. To learn more, see Customize CDK stack synthesis.

Default value: Undefined

Create a Customer Master Key (CMK) for the bootstrap bucket (you will be charged but can customize permissions, modern bootstrapping only).

This option is not compatible with --bootstrap-kms-key-id.

Default value: Undefined

The AWS KMS master key ID to use for the SSE-KMS encryption.

Provide this option to override the default AWS KMS key used to encrypt the Amazon S3 bucket.

This option is not compatible with --bootstrap-customer-key.

Default value: Undefined

The managed IAM policy ARNs that should be attached to the deployment role assumed by AWS CloudFormation during deployment of your stacks.

By default, stacks are deployed with full administrator permissions using the AdministratorAccess policy.

You can provide this option multiple times in a single command. You can also provide multiple ARNs as a single string, with the individual ARNs separated by commas. The following is an example:

$ cdk bootstrap --cloudformation-execution-policies "arn:aws:iam::aws:policy/AWSLambda_FullAccess,arn:aws:iam::aws:policy/AWSCodeDeployFullAccess"

To avoid deployment failures, be sure that the policies you specify are sufficient for any deployments that you will perform into the environment being bootstrapped.

This option applies to modern bootstrapping only.

Default value: []

Specify the name of a permissions boundary to use.

This option is not compatible with --example-permissions-boundary.

Default value: Undefined

Use the example permissions boundary, supplied by the AWS CDK.

This option is not compatible with --custom-permissions-boundary.

The CDK supplied permissions boundary policy should be regarded as an example. Edit the content and reference the example policy if you are testing out the feature. Convert it into a new policy for actual deployments, if one does not already exist. The concern is to avoid drift. Most likely, a permissions boundary is maintained and has dedicated conventions, naming included.

For more information on configuring permissions, including using permissions boundaries, see the Security and Safety Dev Guide.

Default value: Undefined

Configure whether to execute the change set.

Default value: true

Always bootstrap, even if it would downgrade the bootstrap template version.

Default value: false

Show command reference information for the cdk bootstrap command.

Use previous values for existing parameters.

Once a bootstrap template is deployed with a set of parameters, you must set this option to false to change any parameters on future deployments. When false, you must re-supply all previously supplied parameters.

Default value: true

Block public access configuration on the Amazon S3 bucket that is created and used by the CDK CLI.

Default value: true

Nine-digit string value that is unique for each bootstrap stack. This value is added to the physical ID of resources in the bootstrap stack.

By providing a qualifier, you avoid resource name clashes when provisioning multiple bootstrap stacks in the same environment.

When you change the qualifier, your CDK app must pass the changed value to the stack synthesizer. For more information, see Customize CDK stack synthesis.

Default value: hnb659fds. This value has no significance.

Instead of bootstrapping, print the current bootstrap template to the standard output (stdout). You can then copy and customize the template as necessary.

Default value: false

Tags to add to the bootstrap stack in the format of KEY=VALUE.

Default value: []

Use the template from the given file instead of the built-in one.

Toggle AWS CloudFormation termination protection on the bootstrap stack.

When true, termination protection is enabled. This prevents the bootstrap stack from being accidentally deleted.

To learn more about termination protection, see Protecting a stack from being deleted in the AWS CloudFormation User Guide.

Default value: Undefined

The name of the bootstrap stack to create.

By default, cdk bootstrap deploys a stack named CDKToolkit into the specified AWS environment. Use this option to provide a different name for your bootstrap stack.

The CDK CLI uses this value to verify your bootstrap stack version.

Default value: CDKToolkit

Required: Yes

The AWS account IDs that should be trusted to perform deployments into this environment.

The account performing the bootstrapping will always be trusted.

This option requires that you also provide --cloudformation-execution-policies.

You can provide this option multiple times in a single command.

This option applies to modern bootstrapping only.

To add trusted accounts to an existing bootstrap stack, you must specify all of the accounts to trust, including those that you may have previously provided. If you only provide new accounts to trust, the previously trusted accounts will be removed.

The following is an example that trusts two accounts:

$ cdk bootstrap aws://123456789012/us-west-2 --trust 234567890123 --trust 987654321098 --cloudformation-execution-policies arn:aws:iam::aws:policy/AdministratorAccess
 ⏳  Bootstrapping environment aws://123456789012/us-west-2...
Trusted accounts for deployment: 234567890123, 987654321098
Trusted accounts for lookup: (none)
Execution policies: arn:aws:iam::aws:policy/AdministratorAccess
CDKToolkit: creating CloudFormation changeset...
 ✅  Environment aws://123456789012/us-west-2 bootstrapped.

Default value: []

The AWS account IDs that should be trusted to look up values in this environment.

Use this option to give accounts permission to synthesize stacks that will be deployed into the environment, without actually giving them permission to deploy those stacks directly.

You can provide this option multiple times in a single command.

This option applies to modern bootstrapping only.

Default value: []
