Article Summary

Release Templates are Deprecated

With the introduction of variable prompts to Pipelines in BuildMaster 2022, and the planned removal of Deployables, Release Templates have become redundant, so we've deprecated them.

Release templates serve to add a layer of consistency to the release creation process by assigning default properties (e.g., pipeline selection, initial included deployables ), prompting for variables at various points in the release lifecycle, and simplifying Release & Deployment API usage.

Release templates are application-specific, but can be easily copied into other applications using JSON text mode.


Release templates consist of three primary components:

  1. Pipeline - the default pipeline selection when creating a release
  2. Deployables - the default deployables that are included or referenced when creating a release
  3. Template Variable Prompts - defines the variable prompts that occur during release creation, build creation, and deployment in a pipeline stage. Template variable configurations are the only settings in a release template that are considered "live", so changing them can change the prompts during build creation or release deployment that are currently assigned to the template.

Template Variables and Configurations


Release template variables are configurable at any of three levels:

  1. Release creation - when a new share is created, inputs for the specified variables appear, and once the share is created, the corresponding Release Variables are created. These variable values can be edited later on the Release Details page.
  2. Build creation - when creating a new build of a release with an assigned template, inputs for the specified variables are displayed, and once the build is created, the corresponding Build Variables will be created. These variable values can be edited later on the Build Details page.
  3. Deployment to a pipeline stage - when deploying a build of a release with an assigned template, inputs are displayed on the Deploy to Stage page, and once the deployment starts, the corresponding Execution Variables will be injected into the deployment and are not editable (but they can be overridden within a deployment plan using the Set Variable statement).


There are four types of Template Variables:

  1. Text - a simple string value whose prompt is presented as a text box
  2. Checkbox - a simple boolean value with optional description whose prompt is presented as a checkbox
  3. List - a collection of multiple values defined in the template variable configuration whose prompt is presented either as a dropdown list or as a tag text box if the list is not limited to the elements specified in the configuration.
  4. Dynamic List - a collection of values such as a list of BuildMaster servers, environments, or an external source (e.g. ProGet package IDs/versions). These values are extensible and can be added via List Variable Sources. The prompt is presented as a text field with auto-completed values generated from the configuration source.

Common Template Variable Configuration

Each of the four template variable types can be configured in different ways, but the following options are the same for all of them:

  • Initial value - the pre-filled value that will appear in a rendered variable prompt
  • Required - indicates that a value must be present to proceed with version/build creation or to perform deployment
  • Obscure the value of this variable from casual viewing - indicates that a corresponding release or build variable is hidden from UI when it is created and requires additional editing permissions to view it. Note that this is not a means to "secure" a variable value, which is handled by Resource Credentials.

Creating a Release Template

To create a release template, in the context of an application, select the Releases tab in the Releases project sub-navigation menu. Although the UI editor is the recommended method for creating release templates, it is also possible to create them from a JSON object.

Default Release Template

As of BuildMaster 6.1.11, a release template named Default is automatically used for shares for which no template is selected. From the perspective of UI, this template also behaves slightly differently: it is not displayed as an associated template on the release overview page, and the release template selection option is hidden if there is only one template named Default.

Using a Release Template

Once a release template is created, it can be used in one of two places: create a new release from the UI, or the Create Release from Template API endpoint.

If there is only a single release template for an application, that release template is selected by default when a new release. Once a release is assigned to a release template, each of the 3 variable properties that contain template variable configurations will be prompted for values according to the Hierarchy section above.

A release may be assigned a different release template at any time as long as the release is active. Note, however, that this may change the variable prompts whose values are expected by a deployment plan.

JSON Format

Release Template Object

Name*a string representing the name of the release template
Pipeline*a string representing the name of the default pipeline during release creation
ReleaseVariablesan array of Variable objects, each object represents a variable prompt that occurs during release creation
BuildVariablesan array of Variable objects, each object represents a variable prompt that occurs during build creation
DeploymentVariablesan array of Variable objects, each object represents a variable prompt that occurs during deployment to a specified pipeline stage (or all stages)
DefaultDeployableOptiona string value, one of:

1. PreviousRelease: default deployables will be identical to the highest-sequenced release

2. PreviousReleaseSameTemplate: default deployables will be identical to the highest-sequenced release that is also associated with this release template

3. SpecificVersions: (advanced) default deployables are not included in the release, but referenced and assigned specific release numbers (requires Deployables property values with ReferencedReleaseNumber set)

Deployablesan array of Deployable objects

Variable Object

Name*a string representing the name of the variable, this value is unique per each ReleaseVariables, BuildVariables properties, and unique in DeploymentVariables section if all names are associated with a PipelineStageName property
Descriptiona string describing the variable that if supplied, is displayed in the UI instead of the variable name
InitialValuea string representing the initial value of a variable (i.e., the text or selected list value when prompted)
Requireda boolean indicating whether a prompted value must be supplied
Sensitivea boolean indicating whether a value is obscured from the UI
Typea string indicating the type of the variable, one of: Text, List, DynamicList, or Checkbox
PipelineStageNamesan array of strings representing the names of the pipeline stages the variable applies to, null/empty representing all stages. This value is ignored if not under the release template's DeploymentVariables property
ListValuesan array of possible List variable values. This property is ignored if the Type is not "List"
ListMultiplea boolean indicating whether selection of multiple items in a List variable is allowed
ListRestricta boolean indicating whether prompted items are restricted to values in ListValues
ListSourceDescription(automatically generated for informational purposes and not settable)
ListSourceXmla persisted XML string containing the serialized List Source configuration, this value is for informational/copying purposes and is not recommended to be configured manually as text
ListVariableSource(automatically generated for informational purposes and not settable)

Deployable Object

Name*a string representing the name of the deployable
ReferencedReleaseNumbera string representing the release number of the deployable to reference, this value is required if the DefaultDeployableOption property is set to SpecificVersions

(* indicates a required field)
