# ============================================================
# GBS Java Application Dockerfile 模板 (CentOS 7 + JDK 1.8.0_202)
# 适用于没有项目自带 Dockerfile 的场景，通过本地 JDK 打包
# ============================================================
# Build context 目录结构:
#   .
#   ├── Dockerfile
#   ├── jdk1.8.0_202/     (从主节点 /opt/jdk1.8.0_202 复制)
#   └── target/
#       └── *.jar         (应用 JAR 文件)
# ============================================================
