Ask HN: How do you manage shared code across microservices?
Ask HN: How do you manage shared code across microservices?

We are moving off our legacy monolithic architecture to a microservice based architecture. We are about four years into the project and we have 200 distinct microservices. When we first started out on this endeavor we created a parent POM called common-service. This POM declares dependencies such as Hibernate, Spring Boot, and some homegrown common libraries (the most important being a JAR that handles service discovery, rather than each service having to implement service discovery on their own). Now that we have 200 services running in production, it is a difficult to roll out new versions of common-service for a variety of reasons - some teams don't have the capacity, some teams prioritize business requirements over upgrades, etc. How do you handle this in your organization? Do you have shared code across your microservices? Is it an anti-pattern to share code across microservices? PS: We are going to start implementing Kubernetes. Kubernetes will require many changes to our common-service codebase so I figured I would see if anyone had any good ideas out there. Thank you.
