Composer在Docker容器中如何使用

FROM php:8.2-cli
<h1>安装系统依赖（如git、curl等，Composer可能需要）</h1><p>RUN apt-get update && apt-get install -y git unzip</p><h1>下载并安装Composer</h1><p>COPY --from=composer:latest /usr/bin/composer /usr/bin/composer</p><h1>设置工作目录</h1><p>WORKDIR /app</p><h1>复制composer.json和composer.lock</h1><p>COPY composer.json composer.lock ./</p><h1>安装依赖</h1><p>RUN composer install --no-dev --no-scripts --no-progress --no-autoloader</p><h1>复制应用代码</h1><p>COPY . .</p><h1>生成自动加载文件（可选）</h1><p>RUN composer dump-autoload --optimize</p>

# 第一阶段：构建依赖
FROM php:8.2-cli as builder
<p>RUN apt-get update && apt-get install -y git unzip
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer</p><p>WORKDIR /app
COPY composer.json composer.lock ./
RUN composer install --no-dev --no-scripts --no-progress</p><h1>第二阶段：运行环境</h1><p>FROM php:8.2-cli-alpine</p><p>RUN apk add --no-cache tzdata
WORKDIR /app
COPY --from=builder /app/vendor /app/vendor
COPY . .</p><p>CMD ["php", "index.php"]</p>
