  Kotlin Spring-WebFlux R2DBC Redisson K8S Microservice

More details and source code of the full project you can find GitHub repository here, of course always in real-world projects, business logic and infrastructure code is much more complicated, and we have to implement many more necessary features. I hope this article is usefully and helpfully, and be happy to receive any feedback or questions, feel free to contact me by email or any messengers :)

• Redisson

  3 22,706 9.9 Java

  Redisson - Easy Redis Java client and Real-Time Data Platform. Sync/Async/RxJava/Reactive API. Over 50 Redis based Java objects and services: Set, Multimap, SortedSet, Map, List, Queue, Deque, Semaphore, Lock, AtomicLong, Map Reduce, Bloom filter, Spring Cache, Tomcat, Scheduler, JCache API, Hibernate, RPC, local cache ...

  

Source code you can find in the GitHub repository. he main idea of this project is the implementation of microservice using Kotlin, Spring WebFlux, PostgresSQL, and Redis with metrics and monitoring and deploying it to k8s. For interacting with PostgresSQL we will use reactive Spring Data R2DBC and for Redis caching using Redisson.

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• helm-charts

  97 4,637 9.7 Mustache

  Prometheus community Helm charts

  

For working with k8s like to use Helm, deployment for the microservice is simple and has deployment itself, Service, ConfigMap and ServiceMonitor. The last one is required because for monitoring use kube-prometheus-stack helm chart
