Platform Stability

Each platform is marked as either pre-alpha, alpha, beta, or stable. This document outlines the rough criteria for each.

Pre-Alpha

Requirements

  • Initial static Terraform assets are added to this repo and underging active development
  • No installer integration

Packaging

  • None

User Flow

Development workflows only

Alpha

  • Manually tested and can reliably produce minimally functioning clusters
    • Kuberntes API works
    • Authenticated Tectonic Console works

Packaging

  • Assets are packaged into the official Tectonic Installer tarball with every Tectonic release.

User Flow

  1. Manually create terraform.tfvars file
  2. Use static Terraform assets contained in installer tarball
  3. Manually run Terraform

Beta

Requirements

  • Best practices for platform implemented
    • Network security
    • Automated testing results are published
    • DNS & Load Balancing
    • Generates HA / Multi-AZ infrastructure
  • Automated testing results are published
    • Kubernetes e2e and conformance tests pass
    • Tectonic smoke tests work
  • Cloud Provider enabled for the platform
  • Tectonic automated updates work
  • README documents all customizations
  • Two documented platform users

Packaging

  • Assets are packaged into the official Tectonic Installer tarball with every Tectonic release.
  • [optoinal] Installer UI is built to guide user through the configuration process.

User Flow

  1. Use GUI installer to generate terraform.tfvars file, or manually create it.
  2. Use static Terraform assets contained in installer tarball
  3. Manually run terraform

Stable

Requirements

  • Automated tests pass for all supported releases
  • Tectonic Installer UI for platform (optional)

Packaging

  • [optional] GUI Installer reads Terraform assets
  • [optional] GUI Installer backend runs equivalent of terraform apply on behalf of the user via Go client libraries
  • [optional] GUI shows status info and links to Console once complete

User Flow

GUI Only

  1. Use GUI installer configure cluster
  2. Click to provision cluster
  3. GUI shows status info
  4. Click to go directly to Tectonic Console

Non-GUI

  1. Manually create terraform.tfvars file
  2. Use static Terraform assets contained in installer tarball
  3. Manually run Terraform
