Terraform for Kubernetes

An exploration into the use of Terraform to provision Kubernetes clusters on popular IaaS.

Vision

Launch a relatively comprehensive end-to-end demo environment for discussion purposes and/or hands-on workshops in under an hour.

Getting Started

Choose your own adventure on one of the following cloud providers

• Google Cloud Platform (GKE)
• Microsoft Azure (AKS)
• Amazon Web Service (EKS)
• VMWare Tanzu Kubernetes Grid
  • on AWS management and workload clusters
  • on Azure management and workload clusters
• VMWare Tanzu Kubernetes Grid Integrated

Or provision new / attach existing Kubernetes clusters via

• VMWare Tanzu Mission Control

Current experiments

• Identity management
• Add DNS Zone management
• Add Certificate management
• Add Ingress and External DNS
• Install Sealed Secrets
• Install a registry like ACR, GCR, Harbor or JCR
• Install VMWare Tanzu Build Service
• Install cf-for-k8s
• Install VMWare Tanzu Application Service for Kubernetes
• Install Tanzu Services Manager
• Install Cloud Service Broker
• Install Kubeapps
• Install Stratos
• Install Loki Stack
• Install EFK Stack
• Integrate a cloud provider's blobstore or install Minio
• Integrate VMware Tanzu Observability
• Provision a distributed version control system with Gitea
• Enable continuous integration (and deployment) with Concourse or Jenkins
• Enable continuous deployment with Argo CD or Tekton
• Install edukates a set of custom resources used to deploy workshop training portals

Organization

Sub-directories of this repository contain

• bom
  • Bill of materials; what do you need to get started?
• experiments
  • Progressively build out a platform to deliver software delivery agility underpinned by Kubernetes
• modules
  • Building blocks to be composed as you see fit
• ytt-libs
  • YAML-based templates consumed by ytt then deployed with kapp

Roadmap

Above-mentioned experiments will evolve to include automating base configuration and installation of an additional complement of capabilities/components aimed at modeling a modern enterprise software factory / product delivery supply chain.
