BRD.md

Project structure for continuous deployment

- Dockerfile
- packer.json
- docs/
  - ...
- src/
  - ...
- readme.md
- serverspec.rb

Dockerfile is optional. Packer can build Docker images without a Dockerfile.

Application sourcecode is in the src directory.

Deployment Pipeline

Build

• New version number is designated (using semver)
• Compile (if necessary)
• Lint (if necessary)
• Static Analysis (if necessary)
• Unit tests

When build steps complete, there is a build artifact stored in a central location.

Release

• Packer is run on the packer.json file
• The packer.json file references the latest successful build artifact

When release steps complete there should be

1. An immutable machine image for Amazon
2. An immutable machine image for VMWare
3. A machine image for Vagrant
4. A Docker image

Deploy

• Locally, launch the Vagrant image or the Docker image
• In Amazon, use the AMI
• In VMware, use the VMWare image
