How to use vCluster and Argo Workflow to manage ephemeral test environments

Project structure:

• argo-workflow: CI/CD pipeline templates
  • lang: ArgoWorkflow Templates for supported languages
• hello-world-app folder: Go Hello world application that prints a beautiful octopus 🐙 in ASCII code

Key highlights from the article include:

1. vCluster Usage: The article introduces vCluster as a pivotal tool for creating lightweight, ephemeral Kubernetes clusters. It's interesting how vCluster can be employed to instantiate and manage test environments on-demand, covering the scenarios where temporary clusters are essential for testing.

2. Argo Workflow Implementation: The article delves into the integration of Argo Workflow, a workflow engine for Kubernetes, providing a way to configure the orchestration of the deployment, testing, and teardown processes efficiently. The tool also enables the final user to define another kind of process drawing DAGs (https://argoproj.github.io/argo-workflows/walk-through/dag/). This feature supports complex scenarios where there is a requirement to maximize parallelism when running tasks.
