Build and Deployments

2. Builds
•Versioning
•Packaging
•Selective triggering
•Shared code
Deployments
• Deployment tests
• Blue / Green deployments
• Consumer Driven Testing
• Dark Launching
Agenda

3. Your build and deployments are different
And deploying your application is different
than releasing it to users

4. Builds
Compile Test Package

5. Versioning
MAJOR.MINOR.PATCH
• MAJOR breaking changes
• MINOR feature release
• PATCH bug fixes

6. Package Versions
• 1.0.521
• 1.0.521-develop
• 1.0.0.521
• 1.0.0-hotfix.521
Assembly Versions
• 1.0.521.0
• 1.0.0.521
Versioning

7. Versioning
AssemblyInfo.cs
[assembly: AssemblyInformationalVersion("1.0.521-develop")]
[assembly: AssemblyVersion("1.0.521.0")]
[assembly: AssemblyFileVersion("1.0.521.0")]

8. Versioning
Store it in a file
Version.txt
0.9
Appveyor.yml
# version format
version: 0.9.{build}

9. Selective Triggering

10. Selective Triggering
• Only create a package when something has changed
• More integration testing

11. Selective Triggering

12. NuGet packages
• Pull
• Discoverable (nuget.org)
• Unexpected users
• Just enough documentation
Project references
• Push
• Team knowledge
• Dangerous to reuse
• Handover notes
Shared Code

13. Shared Code

14. Deployments
Deploy Configure Verify

15. Deployment Tests
Is it Happy?

16. Deployment Tests
App
v1.0.1
App.Tests
v1.0.1
Deploy
Check application version
Get deployment tests
Run tests
V1.0.1

17. Consumer Driven Testing
Integration tests from the perspective of your
service’s clients

18. Consumer Driven Testing
Example service
API
Web

19. Consumer Driven Testing
Broker
Web
API
V1.2.1
Web/Api
Tests V1.0.1
Web
v1.0.1
API
Build
Build

20. Consumer Driven Testing
Broker
API
V1.2.2
Web/Api
Tests V1.0.1
Get consumer tests for API
Current version
Run tests
Deploy

21. Consumer Driven Testing
Broker
API
V2.1.5
Web/Api
Tests V1.0.1
Get consumer tests for API
current version
Run tests
Deploy

22. Blue Green Deployments
Have two environments that could be live

23. Blue Green Deployments

24. Blue Green Deployments

25. Dark Launching
Previewing features to a small set of users
to test your application in the wild

26. Dark Launching
1.1.0
Feature 1
1.1.0
Feature 1
