sentinel 自定义 dashboard 用户名密码

默认情况下，sentinel dashboard 用户名密码为 sentinel / sentinel ，这里我使用重写 镜像的方式：

// 定义 Dockerfile

$ cat Dockerfile 
# 基于现有 Sentinel Dashboard 镜像
FROM bladex/sentinel-dashboard:1.8.4

# 重新定义 ENTRYPOINT，确保参数顺序正确
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-Dserver.port=8858", "-Dcsp.sentinel.api.port=8719", "-Dsentinel.dashboard.auth.username=xiodi-admin", "-Dsentinel.dashboard.auth.password=xxxxx", "-Dcsp.sentinel.dashboard.server=localhost:8858", "-Dproject.name=sentinel-dashboard", "-jar", "app.jar"]

// 重写构建镜像

$ docker build harbor.xiodi.cn/bladex/sentinel-dashboard:1.8.4 .
