DockerImageCode

class aws_cdk.aws_lambda.DockerImageCode

Bases: object

Code property for the DockerImageFunction construct.

ExampleMetadata:

infused

Example:

lambda_.DockerImageFunction(self, "AssetFunction",
    code=lambda_.DockerImageCode.from_image_asset(path.join(__dirname, "docker-handler"))
)

Static Methods

classmethod from_ecr(repository, *, cmd=None, entrypoint=None, tag=None, tag_or_digest=None, working_directory=None)

Use an existing ECR image as the Lambda code.

Parameters:

  • repository (IRepository) – the ECR repository that the image is in.

  • cmd (Optional[Sequence[str]]) – Specify or override the CMD on the specified Docker image or Dockerfile. This needs to be in the ‘exec form’, viz., [ 'executable', 'param1', 'param2' ]. Default: - use the CMD specified in the docker image or Dockerfile.

  • entrypoint (Optional[Sequence[str]]) – Specify or override the ENTRYPOINT on the specified Docker image or Dockerfile. An ENTRYPOINT allows you to configure a container that will run as an executable. This needs to be in the ‘exec form’, viz., [ 'executable', 'param1', 'param2' ]. Default: - use the ENTRYPOINT in the docker image or Dockerfile.

  • tag (Optional[str]) – (deprecated) The image tag to use when pulling the image from ECR. Default: ‘latest’

  • tag_or_digest (Optional[str]) – The image tag or digest to use when pulling the image from ECR (digests must start with sha256:). Default: ‘latest’

  • working_directory (Optional[str]) – Specify or override the WORKDIR on the specified Docker image or Dockerfile. A WORKDIR allows you to configure the working directory the container will use. Default: - use the WORKDIR in the docker image or Dockerfile.

Return type:

DockerImageCode

classmethod from_image_asset(directory, *, cmd=None, entrypoint=None, working_directory=None, build_args=None, file=None, invalidation=None, network_mode=None, platform=None, repository_name=None, target=None, extra_hash=None, exclude=None, follow=None, ignore_mode=None, follow_symlinks=None)

Create an ECR image from the specified asset and bind it as the Lambda code.

Parameters:

  • directory (str) – the directory from which the asset must be created.

  • cmd (Optional[Sequence[str]]) – Specify or override the CMD on the specified Docker image or Dockerfile. This needs to be in the ‘exec form’, viz., [ 'executable', 'param1', 'param2' ]. Default: - use the CMD specified in the docker image or Dockerfile.

  • entrypoint (Optional[Sequence[str]]) – Specify or override the ENTRYPOINT on the specified Docker image or Dockerfile. An ENTRYPOINT allows you to configure a container that will run as an executable. This needs to be in the ‘exec form’, viz., [ 'executable', 'param1', 'param2' ]. Default: - use the ENTRYPOINT in the docker image or Dockerfile.

  • working_directory (Optional[str]) – Specify or override the WORKDIR on the specified Docker image or Dockerfile. A WORKDIR allows you to configure the working directory the container will use. Default: - use the WORKDIR in the docker image or Dockerfile.

  • 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). Default: - no build args are passed

  • file (Optional[str]) – Path to the Dockerfile (relative to the directory). Default: ‘Dockerfile’

  • invalidation (Union[DockerImageAssetInvalidationOptions, Dict[str, Any], None]) – Options to control which parameters are used to invalidate the asset hash. Default: - hash all parameters

  • network_mode (Optional[NetworkMode]) – Networking mode for the RUN commands during build. Support docker API 1.25+. Default: - no networking mode specified (the default networking mode NetworkMode.DEFAULT will be used)

  • platform (Optional[Platform]) – Platform to build for. Requires Docker Buildx. Default: - no platform specified (the current machine architecture will be used)

  • repository_name (Optional[str]) – (deprecated) ECR repository name. Specify this property if you need to statically address the image, e.g. from a Kubernetes Pod. Note, this is only the repository name, without the registry and the tag parts. Default: - the default ECR repository for CDK assets

  • target (Optional[str]) – Docker target to build to. Default: - no target

  • extra_hash (Optional[str]) – (deprecated) Extra information to encode into the fingerprint (e.g. build instructions and other inputs). Default: - hash is only based on source content

  • exclude (Optional[Sequence[str]]) – (deprecated) Glob patterns to exclude from the copy. Default: nothing is excluded

  • follow (Optional[FollowMode]) – (deprecated) A strategy for how to handle symlinks. Default: Never

  • ignore_mode (Optional[IgnoreMode]) – (deprecated) The ignore behavior to use for exclude patterns. Default: - GLOB for file assets, DOCKER or GLOB for docker assets depending on whether the ‘

  • follow_symlinks (Optional[SymlinkFollowMode]) – A strategy for how to handle symlinks. Default: SymlinkFollowMode.NEVER
