Pipelines Extension Resource Model

Pipelines enables creation of user-defined resources to extend the Pipelines DSL.

Resources typically contain information needed for a step in a pipeline to execute and can also be used to store information produced by a step.

Extension resources enable Pipelines users to extend the Pipelines DSL by specifying their own resource types. When loaded into Pipelines, these user-defined resources can be used in any pipeline just like any other resource in the Pipelines DSL. In this way, teams and organizations can create and share their own re-usable, custom resource types for frequently used information in their pipelines.

Extension resources are defined within a namespace, to ensure that all resources in the set have unique names.

Extension resources are versioned, and can be invoked in pipelines by their semantic version number to ensure compatibility.

Files

Extension resource definitions must be stored in a subdirectory path of the form: resources/<namespace>/<resourceTypeName>.

  • namespace is the namespace for the set of extension sets. This parent subdirectory may contain multiple step definition subdirectories.

  • resourceTypeName is the named type of resource. Must be alphabetic characters only, and is case-sensitive. The subdirectory can hold the following files to define the resource.

Syntax Model

This is the syntax model for the resource.

Tags

You can define the following tags in the resourceModel.yml file.

description

A user-friendly description of the resource's function that will be available for display in the Pipelines UI. This is optional.

platforms

Defines the operating system for the node. Linux and Windows operating systems are supported.

This tag is optional and Linux is the default operating system when this tag is not specified.

os

Specifies the operating system. Linux and Windows are supported.

configuration

Begins a block of property definitions. Each property definition begins with the name of the property (letters only, case-sensitive), followed by these subordinate tags:

Tag

Description of usage

Required/Optional

type

Specifies an inbuilt or user-defined data type.

Required

required

When set as true, specifies that the property is mandatory. If no value is provided, pipeline sync will fail.

Default is false.

Optional

immutable

When set to true, the field cannot be changed from its initial value.

Optional

validate

Begins a validation specification block.

Shell Scripts

An extension resource definition may include optional shell scripts to be executed when the resource is used in a step as an input or output. These may be useful for:

  • Additional validation of properties

  • Testing for a property value to trigger a conditional action

onInput.sh

When present in the resource definition's repository directory, the onInput.sh shell script will be executed whenever the resource is named among the step's inputResources.

onInput.sh

test_input() {
  echo "onInput Executed"
  echo "resource name: $1"
}

execute_command "test_input %%context.resourceName%%"
onOutput.sh

When present in the resource definition's repository directory, the onOutput.sh shell script will be executed whenever the resource is named among the step's OutputResources.

onOutput.sh

test_output() {
  echo "onOutput Executed"
  echo "resource name: $1"
}

execute_command "test_output %%context.resourceName%%"
