Checksum hook

The checksum hook calculates a checksum from a specified directory. The checksum is calculated recursively, i.e. all files and directories under the specified directory are included in the checksum.

Properties

Here are the properties of the Checksum hook:

Key	Required	Type	Description
type	yes	string	Type of the hook, this must be checksum.
name	yes	string	Name of the hook.
dir	yes	string	Path to the directory from where the checksum should be calculated. The path can be absolute or relative to the project directory.
encoding	no	string	Encoding used to encode the calculated checksum. Supported values are base64 (default) and hex.
operation	no	string	Operations during which the hook should be executed. Supported operations are: create, update, delete. Accepts a single operation or a list of operations. By default, a hook is executed on every operation.
stage	no	string	Stages during which the hook should be executed. Supported values are: before, after. Accepts a single stage or a list of stages. By default, a hook is executed on every stage.
status	no	string	Statuses during which the hook should be executed. Available on when stage is after. Supported values are: success = The operation succeeded, failed = The operation failed, cancelled = The operation was cancelled. By default, a hook is executed on every status.

Examples

Calculate a checksum from a directory lambda/scripts located in the project directory.

- name: my-checksum
  type: checksum
  dir: lambda/scripts

The same as above but using the hex encoding.

- name: my-hex-checksum
  type: checksum
  dir: lambda/scripts
  encoding: hex
