## 第一阶段 ====> Nodejs打包编译输出前端资源
FROM node:18-alpine AS buildNode

ENV FRONTEND_DIR = "/jenkins/.jenkins/workspace/ems_frontend_vue3"

## 工作目录存放程序源码
WORKDIR /frontend

## 复制实际需要的文件到工作目录
COPY ${FRONTEND_DIR} ./

RUN npm config set registry https://registry.npmmirror.com
RUN npm install && npm run build

## 第二阶段 ====> GO打包编译输出后端程序
FROM golang:alpine AS buildGo

ARG VERSION

ENV BACKEND_DIR = "/jenkins/.jenkins/workspace/ems_backend"

ENV CGO_ENABLED 0
ENV GOOS linux
ENV GOPROXY https://goproxy.cn,direct

WORKDIR /backend

## 复制实际需要的文件到工作目录
COPY ${BACKEND_DIR}/docker ./docker
COPY ${BACKEND_DIR}/restagent/config ./restagent/config

## 第三阶段 ====> 构建前后端融合镜像
FROM alpine

## 安装时区工具
RUN apk add --no-cache tzdata nginx openssh \
    && ssh-keygen -A \
    && adduser -D sshuser \
    && echo 'sshuser:password' | chpasswd \
    && mkdir /home/sshuser/.ssh \
    && chmod 700 /home/sshuser/.ssh
