Artifacts from Build Triggers


When an external CI system triggers a pipeline, Spinnaker can use the CI build information to inject relevant artifacts into the pipeline. The instructions here assume that you have set up a CI system and are familiar with using property files to pass variables from CI builds to Spinnaker pipelines.

The extraction of artifacts from the build information is done via a Jinja template; the template uses the trigger as context and outputs a list of artifacts to inject into the pipeline. Spinnaker provides a set of standard templates to use for artifact extraction, which users can augment with custom templates.

Select a template

To configure Spinnaker to use a Jinja template for artifact extraction, export the following properties from your CI build:

  • messageFormat: the name of the Jinja template to use
  • customFormat: true if messageFormat refers to a user-configured template; false or omitted if it refers to a Spinnaker-supplied template

For example, to use the Spinnaker-provided JAR template, you would export the following properties from your CI job:


The recommended way to configure artifact templates is by using the hal config artifact templates Halyard command:

hal config artifact templates add <name of template> --template-path <path to the template> 

As an alternative, you can manually configure templates by adding the following to igor-local.yml:

  - name: <name of template>
    templatePath: <path to the template>

(Before Spinnaker 1.13, this manual configuration went into echo-local.yml. As of 1.13, it goes in igor-local.yml.)

You can then use the configured custom template by exporting the following as properties from your CI build:

messageFormat=<name of template>

Bind variables into templates

In general, artifact-extracting templates will read other properties that are exported by the CI job. The general pattern is to export any build-specific information in the property file and to have the Jinja template construct the artifact by looking in

For example, consider a Jenkins job uploads a .jar file to a maven repository. We might define a custom Jinja template custom-jar.jinja as follows:

    "reference": "{{ }}-{{ properties.artifact }}-{{ properties.version }}",
    "name": "{{ properties.artifact }}-{{ properties.version }}",
    "version": "{{ properties.version }}",
    "type": "maven/file"

We could then generate a useful artifact by having the CI job export the following:


Spinnaker > 1.15.x uses Jinjava 2.2.3 which does not support methods such as tojson. Make sure to use supported Jinja syntax

Supplied templates

The templates that are supplied with Spinnaker can be found in the following folder.


The JAR template creates an artifact representing a JAR archive in a Maven or Ivy repository. This template expects the following properties to be exported:

  • group
  • artifact
  • version
  • (optional) classifier

By default, the artifact represents an archive in a Maven repository; to create an artifact for an archive in an Ivy repository, export the property repotype=ivy.
