StackSynthesizer

class aws_cdk.StackSynthesizer

Bases: object

Base class for implementing an IStackSynthesizer.

This class needs to exist to provide public surface area for external implementations of stack synthesizers. The protected methods give access to functions that are otherwise @_internal to the framework and could not be accessed by external implementors.

Methods

abstract add_docker_image_asset(*, source_hash, directory_name=None, docker_build_args=None, docker_build_target=None, docker_file=None, docker_outputs=None, executable=None, network_mode=None, platform=None)

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 intructions 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.

Parameters
  • source_hash (str) – The hash of the contents of the docker build context. This hash is used throughout the system to identify this image and avoid duplicate work in case the source did not change. NOTE: this means that if you wish to update your docker image, you must make a modification to the source (e.g. add some metadata to your Dockerfile).

  • directory_name (Optional[str]) – The directory where the Dockerfile is stored, must be relative to the cloud assembly root. Default: - Exactly one of directoryName and executable is required

  • docker_build_args (Optional[Mapping[str, str]]) – Build args to pass to the docker build command. Since Docker build arguments are resolved before deployment, keys and values cannot refer to unresolved tokens (such as lambda.functionArn or queue.queueUrl). Only allowed when directoryName is specified. Default: - no build args are passed

  • docker_build_target (Optional[str]) – Docker target to build to. Only allowed when directoryName is specified. Default: - no target

  • docker_file (Optional[str]) – Path to the Dockerfile (relative to the directory). Only allowed when directoryName is specified. Default: - no file

  • docker_outputs (Optional[Sequence[str]]) – Outputs to pass to the docker build command. Default: - no build args are passed

  • executable (Optional[Sequence[str]]) – An external command that will produce the packaged asset. The command should produce the name of a local Docker image on stdout. Default: - Exactly one of directoryName and executable is required

  • network_mode (Optional[str]) – Networking mode for the RUN commands during build. Requires Docker Engine API v1.25+. Specify this property to build images on a specific networking mode. Default: - no networking mode specified

  • platform (Optional[str]) – Platform to build for. Requires Docker Buildx. Specify this property to build images on a specific platform. Default: - no platform specified (the current machine architecture will be used)

Return type

DockerImageAssetLocation

abstract add_file_asset(*, source_hash, executable=None, file_name=None, packaging=None)

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 intructions 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.

Parameters
  • source_hash (str) – A hash on the content source. This hash is used to uniquely identify this asset throughout the system. If this value doesn’t change, the asset will not be rebuilt or republished.

  • executable (Optional[Sequence[str]]) – An external command that will produce the packaged asset. The command should produce the location of a ZIP file on stdout. Default: - Exactly one of directory and executable is required

  • file_name (Optional[str]) – The path, relative to the root of the cloud assembly, in which this asset source resides. This can be a path to a file or a directory, depending on the packaging type. Default: - Exactly one of directory and executable is required

  • packaging (Optional[FileAssetPackaging]) – Which type of packaging to perform. Default: - Required if fileName is specified.
