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 the asset hash is calculated. Assets will get rebuilt and uploaded only if their hash has changed.
	//
	// If the asset hash is set to `OUTPUT` (default), 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 the
	// go binary that is output can be different depending on the environment
	// that it was compiled in. If you want to control when the output is changed
	// it is recommended that you use immutable build images such as
	// `public.ecr.aws/bitnami/golang:1.16.3-debian-10-r16`.
	//
	// If the asset hash is set to `SOURCE`, then only changes to the source
	// directory will cause the asset to rebuild. If your go project has multiple
	// Lambda functions this means that an update to any one function could cause
	// all the functions to be rebuilt and uploaded.
	// Experimental.

	// Build arguments to pass when building the bundling image.
