# Dockerfile for ARM64 architecture
# This Dockerfile uses Chromium (auto-downloaded by go-rod) instead of Google Chrome
# because Google Chrome does not provide official Linux ARM64 builds.

# ---- build stage ----
FROM golang:1.24 AS builder

WORKDIR /src
# 配置 Go 模块代理为国内源
ENV GOPROXY=https://goproxy.cn,direct
ENV GOSUMDB=sum.golang.google.cn

COPY go.mod go.sum ./
RUN go mod download

COPY . .
# 移除 GOARCH 硬编码，让构建系统根据目标平台自动选择架构
RUN CGO_ENABLED=0 GOOS=linux go build -ldflags="-s -w" -o /out/app .

# ---- run stage ----
FROM ubuntu:22.04

# 设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 1. 先安装必要工具，然后配置阿里云镜像源
RUN apt-get update && apt-get install -y ca-certificates wget gnupg && \

# 2. 安装 Chromium 运行所需的依赖库
# 注意：不安装 Google Chrome，因为它不支持 ARM64
# go-rod 会在首次运行时自动从 Playwright CDN 下载 ARM64 版本的 Chromium

# 4. 不设置 ROD_BROWSER_BIN 环境变量
# go-rod 会自动检测并下载适合 ARM64 架构的 Chromium 浏览器
# Chromium 下载源：https://playwright.azureedge.net/builds/chromium/
