Types

type BundlingOptions 

type BundlingOptions struct {
	// 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.
	// Experimental.
	AssetHash *string `json:"assetHash" yaml:"assetHash"`
	// Determines how asset hash is calculated. Assets will get rebuild and uploaded only if their hash has changed.
	//
	// If asset hash is set to `SOURCE` (default), then only changes to the source
	// directory will cause the asset to rebuild. This means, for example, that in
	// order to pick up a new dependency version, a change must be made to the
	// source tree. Ideally, this can be implemented by including a dependency
	// lockfile in your source tree or using fixed dependencies.
	//
	// If the asset hash is set to `OUTPUT`, the hash is calculated after
	// bundling. This means that any change in the output will cause the asset to
	// be invalidated and uploaded. Bear in mind that `pip` adds timestamps to
	// dependencies it installs, which implies that in this mode Python bundles
	// will _always_ get rebuild and uploaded. Normally this is an anti-pattern
	// since build.
	// Experimental.
	AssetHashType awscdk.AssetHashType `json:"assetHashType" yaml:"assetHashType"`
	// Optional build arguments to pass to the default container.
	//
	// This can be used to customize
	// the index URLs used for installing dependencies.
	// This is not used if a custom image is provided.
	// Experimental.
	BuildArgs *map[string]*string `json:"buildArgs" yaml:"buildArgs"`
	// Environment variables defined when bundling runs.
	// Experimental.
	Environment *map[string]*string `json:"environment" yaml:"environment"`
	// Docker image to use for bundling.
	//
	// If no options are provided, the default bundling image
	// will be used. Dependencies will be installed using the default packaging commands
	// and copied over from into the Lambda asset.
	// Experimental.
	Image awscdk.DockerImage `json:"image" yaml:"image"`
	// Output path suffix: the suffix for the directory into which the bundled output is written.
	// Experimental.
	OutputPathSuffix *string `json:"outputPathSuffix" yaml:"outputPathSuffix"`

	// The LogGroup where the Lambda function's logs are made available.
	//
	// If either `logRetention` is set or this property is called, a CloudFormation custom resource is added to the stack that
	// pre-creates the log group as part of the stack deployment, if it already doesn't exist, and sets the correct log retention
