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

## 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 ./

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

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

ARG VERSION

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/docker ./docker
COPY ./backend/restagent/config ./restagent/config
COPY ./backend/restagent/etc ./restagent/etc
COPY ./backend/restagent/restagent.go ./restagent/restagent.go

# RUN cd /backend/restagent && go build -ldflags="-s -w" -o backend

## 镜像基座  ====> 编译输出前后端可运行的程序
FROM alpine

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