From 5652a77c8052c7daf9076cb15c1d5a9b9084532e Mon Sep 17 00:00:00 2001 From: Gabriel Roldan Date: Fri, 28 Mar 2025 23:59:13 -0300 Subject: [PATCH] Migrate Gateway to Spring Cloud 2024.0.1 / Spring Boot 3.4.3 - Migrate Gateway module from Spring Cloud 2023.0 to Spring Cloud 2024.0.1 - Upgrade from Spring Boot 3.2.4 to Spring Boot 3.4.3 - Align spring-boot3-starter and observability-spring-boot-3 with same versions - Update logstash-logback-encoder to version 8.0 for Logback 1.5.x compatibility - Ensure correct MDC propagation in WebFlux applications - Verified Gateway container starts correctly with Spring Boot 3.4.3 - Confirmed logging with MDC properties works correctly - Tested Docker build process with CDS enabled --- Makefile | 6 +- docker-build/base-images.yml | 8 + pom.xml |
