Kotlin Spring WebFlux, R2DBC and Redisson microservice in k8s 👋✨💫

1. Kotlin-Spring-Postgres-Redis-Microservice

   1 1 27 0.0 Kotlin

   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 :)

3. Redisson

   2 6 24,373 9.9 Java

   Redisson: Valkey & Redis Java Client and Real-Time Data Platform. Sync/Async/RxJava/Reactive API. Over 50 Valkey and Redis based Java objects and services: Set, Multimap, SortedSet, Map, List, Queue, Deque, Semaphore, Lock, AtomicLong, Map Reduce, Bloom filter, Spring, 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.

4. helm-charts

   3 114 6,152 9.8 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
