Introduction

Spring Boot REST 示例 API 镜像，演示 CRUD 与 Actuator 健康检查，适合 K8s 微服务 PoC 与 CI 集成测试基线。

Details

addozhang/spring-boot-rest 打包轻量 Spring Boot 应用，暴露 REST 端点与 /actuator/health 探针。典型作为 Service Mesh、Ingress 或 HPA 演示的后端样例，与 production 业务镜像相比无领域逻辑、便于替换。生产 PoC 应固定 tag、外置 H2/PostgreSQL 并配置 resource limits，JWT/OAuth 按实际需求扩展。

快速启动

docker run -d --name spring-boot-rest \
  -p 8080:8080 \
  docker.io/addozhang/spring-boot-rest:latest

推荐实践

docker run -d --name spring-boot-rest \
  --restart unless-stopped \
  -p 8080:8080 \
  -e SPRING_PROFILES_ACTIVE=prod \
  -e JAVA_OPTS="-Xms256m -Xmx512m" \
  docker.io/addozhang/spring-boot-rest:1.0.0

核心参数说明

  • -p 8080:8080 — REST API 与 Actuator 端口
  • -e SPRING_PROFILES_ACTIVE=prod — 生产配置 profile
  • -e JAVA_OPTS — JVM 堆内存限制
  • --restart unless-stopped — API 服务持续在线
  • 固定 tag — 应用版本 pin
  • 探针 — /actuator/health 用于 K8s readiness

Ingress 暴露 API；HPA 按 CPU 扩缩，生产替换为真实业务镜像。
