CDKBootstrapAction

(Required)

Specify the name of the action. All action names must be unique within the workflow. Action names are limited to alphanumeric characters (a-z, A-Z, 0-9), hyphens (-), and underscores (_). Spaces are not allowed. You cannot use quotation marks to enable special characters and spaces in action names.

Default: CDKBootstrapAction_nn.

Corresponding UI: Configuration tab/Action display name

Identifier

(CDKBootstrapAction/Identifier)

(Required)

Identifies the action. Do not change this property unless you want to change the version. For more information, see Specifying the action version to use.

Note

Specifying aws/cdk-bootstrap@v2 causes the action to run on the March 2024 image which includes newer tooling such as Node.js 18. Specifying aws/cdk-bootstrap@v1 causes the action to run on the November 2022 image which includes older tooling such as Node.js 16.

Default: aws/cdk-bootstrap@v2.

Corresponding UI: Workflow diagram/CDKBootstrapAction_nn/aws/cdk-bootstrap@v2 label

DependsOn

(CDKBootstrapAction/DependsOn)

(Optional)

Specify an action, action group, or gate that must run successfully in order for this action to run.

For more information about the 'depends on' functionality, see Sequencing actions.

Corresponding UI: Inputs tab/Depends on - optional

Compute

(CDKBootstrapAction/Compute)

(Optional)

The computing engine used to run your workflow actions. You can specify compute either at the workflow level or at the action level, but not both. When specified at the workflow level, the compute configuration applies to all actions defined in the workflow. At the workflow level, you can also run multiple actions on the same instance. For more information, see Sharing compute across actions.

Corresponding UI: none

Type

(CDKBootstrapAction/Compute/Type)

(Required if Compute is included)

The type of compute engine. You can use one of the following values:

EC2 (visual editor) or EC2 (YAML editor)

Optimized for flexibility during action runs.
Lambda (visual editor) or Lambda (YAML editor)

Optimized action start-up speeds.

For more information about compute types, see Compute types.

Corresponding UI: Configuration tab/Advanced - optional/Compute type

Fleet

(CDKBootstrapAction/Compute/Fleet)

(Optional)

Specify the machine or fleet that will run your workflow or workflow actions. With on-demand fleets, when an action starts, the workflow provisions the resources it needs, and the machines are destroyed when the action finishes. Examples of on-demand fleets: Linux.x86-64.Large, Linux.x86-64.XLarge. For more information about on-demand fleets, see On-demand fleet properties.

With provisioned fleets, you configure a set of dedicated machines to run your workflow actions. These machines remain idle, ready to process actions immediately. For more information about provisioned fleets, see Provisioned fleet properties.

If Fleet is omitted, the default is Linux.x86-64.Large.

Corresponding UI: Configuration tab/Advanced - optional/Compute fleet

Timeout

(CDKBootstrapAction/Timeout)

(Required)

Specify the amount of time in minutes (YAML editor), or hours and minutes (visual editor), that the action can run before CodeCatalyst ends the action. The minimum is 5 minutes and the maximum is described in Quotas for workflows in CodeCatalyst. The default timeout is the same as the maximum timeout.

Corresponding UI: Configuration tab/Timeout - optional

Inputs

(CDKBootstrapAction/Inputs)

(Optional)

The Inputs section defines the data that the AWS CDK bootstrap action needs during a workflow run.

Corresponding UI: Inputs tab

Note

Only one input (either a source or an artifact) is allowed for each AWS CDK bootstrap action.

Sources

(CDKBootstrapAction/Inputs/Sources)

(Required if your AWS CDK app is stored in a source repository)

If your AWS CDK app is stored in a source repository, specify the label of that source repository. The AWS CDK bootstrap action synthesizes the app in this repository before starting the bootstrapping process. Currently, the only supported repository label is WorkflowSource.

If your AWS CDK app is not contained within a source repository, it must reside in an artifact generated by another action.

For more information about sources, see Connecting source repositories to workflows.

Corresponding UI: Inputs tab/Sources - optional

Artifacts - input

(CDKBootstrapAction/Inputs/Artifacts)

(Required if your AWS CDK app is stored in an output artifact from a previous action)

If your AWS CDK app is contained in an artifact generated by a previous action, specify that artifact here. The AWS CDK bootstrap action synthesizes the app in the specified artifact into a CloudFormation template before starting the bootstrapping process. If your AWS CDK app is not contained within an artifact, it must reside in your source repository.

For more information about artifacts, including examples, see Sharing artifacts and files between actions.

Corresponding UI: Inputs tab/Artifacts - optional

Outputs

(CDKBootstrapAction/Outputs)

(Optional)

Defines the data that is output by the action during a workflow run.

Corresponding UI: Outputs tab

Artifacts - output

(CDKBootstrapAction/Outputs/Artifacts)

(Optional)

Specify the artifacts generated by the action. You can reference these artifacts as input in other actions.

For more information about artifacts, including examples, see Sharing artifacts and files between actions.

Corresponding UI: Outputs tab/Artifacts

Name

(CDKBootstrapAction/Outputs/Artifacts/Name)

(Required if Artifacts - output is included)

Specify the name of the artifact that will contain the AWS CloudFormation template that is synthesized by the AWS CDK bootstrap action at runtime. The default value is cdk_bootstrap_artifacts. If you do not specify an artifact, then the action synthesizes the template, but won't save it in an artifact. Consider saving the synthesized template in an artifact to preserve a record of it for testing or troubleshooting purposes.

Corresponding UI: Outputs tab/Artifacts/Add artifact/Build artifact name

Files

(CDKBootstrapAction/Outputs/Artifacts/Files)

(Required if Artifacts - output is included)

Specify the files to include in the artifact. You must specify "cdk.out/**/*" to include your AWS CDK app's synthesized AWS CloudFormation template.

Note

cdk.out is the default directory into which synthesized files are saved. If you specified an output directory other than cdk.out in your cdk.json file, specify that directory here instead of cdk.out.

Corresponding UI: Outputs tab/Artifacts/Add artifact/Files produced by build

Environment

(CDKBootstrapAction/Environment)

(Required)

Specify the CodeCatalyst environment to use with the action. The action connects to the AWS account and optional Amazon VPC specified in the chosen environment. The action uses the default IAM role specified in the environment to connect to the AWS account, and uses the IAM role specified in the Amazon VPC connection to connect to the Amazon VPC.

Note

If the default IAM role does not have the permissions required by the action, you can configure the action to use a different role. For more information, see Changing the IAM role of an action.

For more information about environments, see Deploying into AWS accounts and VPCs and Creating an environment.

Corresponding UI: Configuration tab/Environment

Name

(CDKBootstrapAction/Environment/Name)

(Required if Environment is included)

Specify the name of an existing environment that you want to associate with the action.

Corresponding UI: Configuration tab/Environment

Connections

(CDKBootstrapAction/Environment/Connections)

(Optional in newer versions of the action; required in older versions)

Specify the account connection to associate with the action. You can specify a maximum of one account connection under Environment.

If you do not specify an account connection:

The action uses the AWS account connection and default IAM role specified in the environment in the CodeCatalyst console. For information about adding an account connection and default IAM role to environment, see Creating an environment.
The default IAM role must include the policies and permissions required by the action. To determine what those policies and permissions are, see the description of the Role property in the action's YAML definition documentation.

For more information about account connections, see Allowing access to AWS resources with connected AWS accounts. For information about adding an account connection to an environment, see Creating an environment.

Corresponding UI: One of the following depending on the action version:

(Newer versions) Configuration tab/Environment/What's in my-environment?/three dot menu/Switch role
(Older versions) Configuration tab/'Environment/account/role'/AWS account connection

Name

(CDKBootstrapAction/Environment/Connections/Name)

(Required if Connections is included)

Specify the name of the account connection.

Corresponding UI: One of the following depending on the action version:

(Newer versions) Configuration tab/Environment/What's in my-environment?/three dot menu/Switch role
(Older versions) Configuration tab/'Environment/account/role'/AWS account connection

Role

(CDKBootstrapAction/Environment/Connections/Role)

(Required if Connections is included)

Specify the name of the IAM role that the AWS CDK bootstrap action uses to access AWS and add the bootstrap stack. Make sure that you have added the role to your CodeCatalyst space, and that the role includes the following policies.

If you do not specify an IAM role, then the action uses the default IAM role listed in the environment in the CodeCatalyst console. If you use the default role in the environment, make sure it has the following policies.

Note

The permissions shown in the following permissions policy are those required by the cdk bootstrap command to perform its bootstrapping at the time of writing. These permissions may change if the AWS CDK changes its bootstrap command.

Warning

Only use this role with the AWS CDK bootstrap action. It is very permissive, and using it with other actions might pose a security risk.
