Spinnaker Stage Bake (Manifest)

Internal

• Spinnaker Concepts
• Delivery Pipeline for Simple Java Application from GitHub to Kubernetes

Overview

This stage renders the final form of a manifest or a multi-document manifest set, using a template renderer such as Helm.

Configuration

Bake (Manifest) Configuration

Template Renderer

Render Engine: HELM3

Helm Options

Name: the Helm release name for the chart. It determines the name of the artifact produced by this stage. This name will override the "Match Artifact/Name" specified in the Produces Artifact section.

Namespace: the target namespace to release into. If not specified, "default" will be used. ⚠️ There were (yet not elucidated) situations when even if a specific namespace was configured here, the deployment went to "default". That was fixed by overriding the namespace in the Deploy (Manifest) stage.

Template Artifact

Expected Artifact: Artifact from execution context

To define the helm chart to render, there are two choices: Helm repository or GitHub repository. In both cases, the chart to be deployed must be stored remotely as a .tar.gz archive.

Overrides

The files passed to --values parameter must be added as "Overrides/value artifact". Individually specified overrides can also be set in form of key/value pairs.

Produces Artifact

By default, Spinnaker automatically creates an embedded/base64 artifact that is bound when the stage completes, representing the full manifest set to be deployed downstream.
