Introduction
iKubernetes 演示应用镜像，K8s 培训用多版本 HTTP 样例服务，Deployment/Ingress/Service 实验与滚动更新演示靶应用。
Details
ikubernetes/demoapp 是 Kubernetes 培训课程的演示 Web 应用，支持多版本 tag 展示不同响应内容。定位为 K8s 教学/测试 Web 服务；Deployment 滚动更新、Service 负载均衡与 Ingress 路由规则实验的标准样例，无复杂业务逻辑。
快速启动
docker run -d --name demoapp \
-p 8080:8080 \
docker.io/ikubernetes/demoapp:v1.0
推荐实践
docker run -d --name demoapp \
--restart unless-stopped \
-p 8080:8080 \
docker.io/ikubernetes/demoapp:v2.0
核心参数说明
-p 8080:8080— HTTP 服务端口- tag — v1/v2 版本对比
- 用途 — K8s 实验演示
- 轻量 — 无持久化需求
