Deployment Architecture

Goals​

The deployment architecture of ATON shall provide:

  • Reproducible deployments
  • Separation of test and production environments
  • Immutable releases
  • Fast rollback capability
  • Traceability between Git commits and deployed releases
  • Simple command-line interface

Architecture​

Git Repository │ ▼ aton deploy test │ ▼ Release │ ▼ current-test │ Validation │ ▼ aton publish │ ▼ current-prod

Directory Structure​

/opt/projects/aton ├── book/ ├── releases/ ├── current-test └── current-prod

Principles​

  • A release is immutable.
  • Production always points to a tested release.
  • Publishing never rebuilds the project.
  • Rollback only changes a symbolic link.
