class aws_cdk.aws_lambda.EcrImageCode(repository, *, cmd=None, entrypoint=None, tag=None, tag_or_digest=None, working_directory=None)

Bases: Code

Represents a Docker image in ECR that can be bound as Lambda Code.

ExampleMetadata:

fixture=_generated

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_ecr as ecr
import aws_cdk.aws_lambda as lambda_

# repository: ecr.Repository

ecr_image_code = lambda_.EcrImageCode(repository,
    cmd=["cmd"],
    entrypoint=["entrypoint"],
    tag="tag",
    tag_or_digest="tagOrDigest",
    working_directory="workingDirectory"
)
Parameters:

  • repository (IRepository)

  • 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.

Methods

bind(_)

Called when the lambda or layer is initialized to allow this object to bind to the stack, add resources and have fun.

Parameters:

_

Return type:

CodeConfig

bind_to_resource(_resource, *, resource_property=None)

Called after the CFN function resource has been created to allow the code class to bind to it.

Specifically it’s required to allow assets to add metadata for tooling like SAM CLI to be able to find their origins.

Parameters:

  • _resource (CfnResource)

  • resource_property (Optional[str]) – The name of the CloudFormation property to annotate with asset metadata. Default: Code

Return type:

None

Attributes

is_inline

Determines whether this Code is inline code or not.

classmethod from_asset(path, *, readers=None, source_hash=None, exclude=None, follow=None, ignore_mode=None, follow_symlinks=None, asset_hash=None, asset_hash_type=None, bundling=None)

Loads the function code from a local disk path.

Parameters:

  • path (str) – Either a directory with the Lambda code bundle or a .zip file.

  • readers (Optional[Sequence[IGrantable]]) – A list of principals that should be able to read this asset from S3. You can use asset.grantRead(principal) to grant read permissions later. Default: - No principals that can read file asset.

  • source_hash (Optional[str]) – (deprecated) Custom hash to use when identifying the specific version of the asset. For consistency, this custom hash will be SHA256 hashed and encoded as hex. The resulting hash will be the asset hash. NOTE: the source hash is used in order to identify a specific revision of the asset, and used for optimizing and caching deployment activities related to this asset such as packaging, uploading to Amazon S3, etc. If you chose to customize the source hash, you will need to make sure it is updated every time the source changes, or otherwise it is possible that some deployments will not be invalidated. Default: - automatically calculate source hash based on the contents of the source file or directory.

  • 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

  • asset_hash (Optional[str]) – Specify a custom hash for this asset. If assetHashType is set it must be set to AssetHashType.CUSTOM. For consistency, this custom hash will be SHA256 hashed and encoded as hex. The resulting hash will be the asset hash. NOTE: the hash is used in order to identify a specific revision of the asset, and used for optimizing and caching deployment activities related to this asset such as packaging, uploading to Amazon S3, etc. If you chose to customize the hash, you will need to make sure it is updated every time the asset changes, or otherwise it is possible that some deployments will not be invalidated. Default: - based on assetHashType

  • asset_hash_type (Optional[AssetHashType]) – Specifies the type of hash to calculate for this asset. If assetHash is configured, this option must be undefined or AssetHashType.CUSTOM. Default: - the default is AssetHashType.SOURCE, but if assetHash is explicitly specified this value defaults to AssetHashType.CUSTOM.

  • bundling (Union[BundlingOptions, Dict[str, Any], None]) – Bundle the asset by executing a command in a Docker container or a custom bundling provider. The asset path will be mounted at /asset-input. The Docker container is responsible for putting content at /asset-output. The content at /asset-output will be zipped and used as the final asset. Default: - uploaded as-is to S3 if the asset is a regular file or a .zip file, archived into a .zip file and uploaded to S3 otherwise

Return type:
