Introduction

Nginx 官方演示镜像，返回带主机名与环境信息的 Hello 页面，常用于 K8s/Docker 网络与 Ingress 连通性验证。

Details

nginxdemos/nginx-hello 是 NGINX Inc. 提供的极简演示服务，响应 HTML 展示 Pod/容器 hostname 与请求头，广泛用于 Service Mesh、Ingress 与负载均衡测试。镜像无状态、资源占用极低，不适合承载真实业务流量。与 nginx:alpine 相比内置定制页面；实验或 CI 可用 latest，生产演示环境仍建议固定 tag。

快速启动

docker run -d --name nginx-hello \
  -p 8080:80 \
  docker.io/nginxdemos/nginx-hello:latest

推荐实践

docker run -d --name nginx-hello \
  --restart unless-stopped \
  -p 8080:80 \
  docker.io/nginxdemos/nginx-hello:0.25

核心参数说明

  • -p 8080:80 — HTTP 演示页面端口
  • --restart unless-stopped — 探针 demo 持续运行
  • nginx-hello:0.25 — 固定演示版本 tag
  • 用途 — 连通性/灰度验证，非业务应用
  • 轻量 — 无持久化与 env 依赖

多副本可验证 Service 负载均衡；Ingress 指向本 Service 即可测试路由与 TLS。
