Deployment

• Reliability
  • Having development, testing and deployment environments identical is reliable.
    • Operating System (its architecture, version)
    • tooling ([platform-specific] packages)
    • dependencies
    • binaries
    • etc.
  • It is much more reliable, rather than if you develop in one OS, but deploy to another.
• Ease and speed
  • It allows to streamline and automate development processes, such as:
    • setting up a project locally (for development / testing)
    • testing a project in CI
    • deployment to production

All environments, in which the code is developed, tested and deployed to for production, should be identical. This minimizes the risk of the app not working because of any environment-related differences.

• Environment identity can be represented and shared across environments by:
  • .devcontainer.json
  • Dockerfile
  • docker-compose.yml
