2. @crichardson Presentation goal What are the Service template and Microservice chassis patterns A walk through the Live Project series Demo the service template

5. @crichardson Agenda About the Service Template pattern About the Microservice Chassis pattern Live project series: developing a service template and chassis Demoing a service template
6. @crichardson $ mkdir my-new-service
7. @crichardson Configure build logic
8. @crichardson Configure dependencies
9. @crichardson Configure plumbing
10. @crichardson Configure deployment pipeline .github/workflows/build.yml
11. @crichardson Only now can you write your business logic!
12. @crichardson But what about start.spring.io? Convenient BUT Code generator = copy/paste programming Focussed on the Spring Boot ecosystem Simplistic, single Gradle project Generic and flexible - not tailored to your organization’s requirements or standards No sample business logic
13. @crichardson About the service template pattern
14. @crichardson Using a service template to create a new service $ gh clone —private —template myorg/service-template my-new-service $ cd my-new-service
15. @crichardson What you get: build logic Build logic Gradle dependencies { …. } Gradle Plugin configuration Other build logic: GitHub Actions, scripts, …
16. @crichardson What you get: cross cutting concerns Cross-cutting concerns Observability Security Persistence … Testing support
17. @crichardson What you get: sample code Sample application logic Domain logic: entities, repositories, services, …. Adapters: HTTP Controllers, … Tests
18. @crichardson Service template implements: Corporate policies/standards Industry “best practices”
19. @crichardson Agenda About the Service Template pattern About the Microservice Chassis pattern Live project series: developing a service template and chassis Demoing a service template
20. @crichardson A service template (or code generator) = copy/paste Changing requirements = update each service individually
21. @crichardson About the microservice chassis pattern Implements: Corporate policies/standards Industry “best practices”
22. @crichardson Eliminates majority of copy/ paste = small service template build.gradle.kts build.gradle.kts
23. @crichardson When requirements change For example: new version of log4j2 Update microservice chassis and publish a new version Update service template to use new version Update each service to use new version One line change
24. @crichardson Agenda About the Service Template pattern About the Microservice Chassis pattern Live project series: developing a service template and chassis Demoing a service template
25. @crichardson About the Live Project Series Service Template Service Chassis Skeleton application Implement security Package as Docker container Create a microservice chassis Configure observability Live project series
26. @crichardson Starting point = skeleton application Spring Boot Spring Data for JPA Example entity and repository Persistence tests use Testcontainers to run MySQL container …
27. Live project 1: configure observability Observability = key part of production readiness An observable service exposes its internal state to enable monitoring, and troubleshooting Milestones https://microservices.io/patterns/#observability
28. Live project 2: implement security Secure the service API with JSON Web Tokens (JWTs) Milestones https://microservices.io/patterns/#observability
29. Live project 3: Package as a Docker container Build, test and publish a Docker container image to Github container registry Milestones
30. Live project 4: Create a microservice chassis Extract the service chassis framework for the service template Milestones
31. End result: service template + chassis artifacts
32. @crichardson Agenda About the Service Template pattern About the Microservice Chassis pattern Live project series: developing a service template and chassis Demoing a service template
33. Summary: My new Live Project series teaches you how to develop a service template and chassis The service template pattern: Runnable source template for a service Accelerates the creation of a new service Implements plumbing, build logic, …. Built on a Microservice chassis The Microservice chassis pattern Contains the bulk of the plumbing, build logic, …. Minimizes copy/paste duplication in the service template Simplifies maintenance of services
