Extends StackSynthesizer

Use the CDK classic way of referencing assets.

This synthesizer will generate CloudFormation parameters for every referenced asset, and use the CLI's current credentials to deploy the stack.

  • It does not support cross-account deployment (the CLI must have credentials to the account you are trying to deploy to).
  • It cannot be used with CDK Pipelines. To deploy using CDK Pipelines, you must use the DefaultStackSynthesizer.
  • Each asset will take up a CloudFormation Parameter in your template. Keep in mind that there is a maximum of 200 parameters in a CloudFormation template. To use deterministic asset locations instead, use CliCredentialsStackSynthesizer.

Be aware that your CLI credentials must be valid for the duration of the entire deployment. If you are using session credentials, make sure the session lifetime is long enough.

This is the only StackSynthesizer that supports customizing asset behavior by overriding Stack.addFileAsset() and Stack.addDockerImageAsset().

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cdk from 'aws-cdk-lib';
const legacyStackSynthesizer = new cdk.LegacyStackSynthesizer();

Initializer

new LegacyStackSynthesizer()

Properties

NameTypeDescription
bootstrapQualifier?stringThe qualifier used to bootstrap this stack.
lookupRole?stringThe role used to lookup for this stack.

bootstrapQualifier?

Type: string (optional)

The qualifier used to bootstrap this stack.


lookupRole?

Type: string (optional)

The role used to lookup for this stack.

Methods

NameDescription
addDockerImageAsset(asset)Register a Docker Image Asset.
addFileAsset(asset)Register a File Asset.
bind(stack)Bind to the stack this environment is going to be used on.
reusableBind(stack)Produce a bound Stack Synthesizer for the given stack.
synthesize(session)Synthesize the associated stack to the session.

addDockerImageAsset(asset)

public addDockerImageAsset(asset: DockerImageAssetSource): DockerImageAssetLocation

Parameters

  • asset DockerImageAssetSource

Returns

  • DockerImageAssetLocation

Register a Docker Image Asset.

Returns the parameters that can be used to refer to the asset inside the template.

The synthesizer must rely on some out-of-band mechanism to make sure the given files are actually placed in the returned location before the deployment happens. This can be by writing the instructions to the asset manifest (for use by the cdk-assets tool), by relying on the CLI to upload files (legacy behavior), or some other operator controlled mechanism.


addFileAsset(asset)

public addFileAsset(asset: FileAssetSource): FileAssetLocation

Parameters

  • asset FileAssetSource

Returns

  • FileAssetLocation

Register a File Asset.

Returns the parameters that can be used to refer to the asset inside the template.

The synthesizer must rely on some out-of-band mechanism to make sure the given files are actually placed in the returned location before the deployment happens. This can be by writing the instructions to the asset manifest (for use by the cdk-assets tool), by relying on the CLI to upload files (legacy behavior), or some other operator controlled mechanism.


bind(stack)

public bind(stack: Stack): void

Parameters

  • stack Stack

Bind to the stack this environment is going to be used on.

Must be called before any of the other methods are called.


reusableBind(stack)

public reusableBind(stack: Stack): IBoundStackSynthesizer

Parameters

  • stack Stack

Returns

  • IBoundStackSynthesizer

Produce a bound Stack Synthesizer for the given stack.

This method may be called more than once on the same object.


synthesize(session)

public synthesize(session: ISynthesisSession): void

Parameters

  • session ISynthesisSession

Synthesize the associated stack to the session.
