Workflows

There are one workflow for each component, one workflow for the product and another one to create release branches.

Component Workflow

The workflow runs on:

on:
 pull_request:
   branches:
     - main
     - "release/v*"
   paths:
     - "hello-world/**/*"
     - ".github/workflows/hello-*"
 push:
   branches:
     - main
     - "release/v*"
   paths:
     - "hello-world/**/*"
     - ".github/workflows/hello-*"

Job	Description>	Conditional on
quality-checks	Run all quality checks for the component. Linter & Tests.
create-release-tag	Creates a new tag for the component.	if: github.ref == 'refs/heads/main' # only in main branch
create-fix-tag	Creates a new tag for the component.	if: startsWith(github.ref, 'refs/heads/release') # only in release branches
build-release	Create a new build artifact for the component.	if: | always() && (needs.create-release-tag.outputs.tag || needs.create-fix-tag.outputs.tag)

Product Workflow

   types:
     - completed

Job	Description>	Conditional on
[calculate|create]-rc-tag	Calculates or creates the next pre-release tag.	# Just after a workflow completes successfully and the workflows was triggered in main branch if: | github.event.workflow_run.conclusion == 'success' && github.event.workflow_run.head_branch == 'main'
[calculate|create]-fix-tag	Calculates or creates the next fix tag.	# Just after a workflow completes successfully and the workflows was triggered in a release branch if: | github.event.workflow_run.conclusion == 'success' && startsWith(github.event.workflow_run.head_branch, 'release')
release	Release a new version of the product Chart with new versions.	if: | always() && (needs.calculate-rc-tag.outputs.tag || needs.calculate-fix-tag.outputs.tag || needs.calculate-release-tag.outputs.tag)
