生产环境docker nginx+php8.0镜像
自定义创建php8.0镜像，创建dockerfile

FROM php:8.0-fpm# 安装系统依赖
RUN sed -i 's|http://deb.debian.org/debian|http://mirrors.aliyun.com/debian|g' /etc/apt/sources.list && \apt-get update && apt-get install -y \libfreetype6-dev \libjpeg62-turbo-dev \libpng-dev \libzip-dev \libonig-dev \zip \unzip \&& docker-php-ext-configure gd --with-freetype --with-jpeg \&& docker-php-ext-install -j$(nproc) gd \&& docker-php-ext-install pdo pdo_mysql mbstring zip exif pcntl bcmath \&& pecl install redis \&& docker-php-ext-enable redis# 复制PHP配置文件（可选）
#COPY php.ini /usr/local/etc/php/# 设置工作目录
WORKDIR /var/www/html# 运行前的清理
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

在dockerfile目录下执行构建命令

docker build -t php8.0 .

构建完docker images查看
创建docker-compose.yml文件

version: '3.8'services:nginx:image: nginx:latestports:- "80:80"volumes:- ./nginx.conf:/etc/nginx/nginx.conf- ./code:/var/www/htmlnetworks:- my_networkdeploy:replicas: 3restart_policy:condition: on-failurephp:image: php:8.0-fpmvolumes:- ./code:/var/www/htmlnetworks:- my_networkdeploy:replicas: 3restart_policy:condition: on-failurenetworks:my_network:driver: overlay

使用docker stack deploy命令将Stack部署到Swarm集群中。

docker stack deploy -c docker-compose.yml my_stack
