Docker实践02:lnmp环境docker部署

4.5 周庆 Docker 2019-09-11

1. Laravel/Lumen DockerFile(PHP-FPM+Nginx)

这个dockerfile使用最佳场景是laravel/lumen php+nginx 项目, 一下dockerfile文件是非常适合做上线prod最终的部署,不适合做开发环境. 如果搭建开发环境建议使用volume来挂在脚本语言的代码, COPY 比较适合代码发布.

FROM php:7.3-fpm
LABEL author="mojotv.cn"

# 添加编译环境

# 安装composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# 安装nginx
RUN echo "deb http://nginx.org/packages/debian `lsb_release -cs` nginx" \
    | tee /etc/apt/sources.list.d/nginx.list && \
    curl -fsSL https://nginx.org/keys/nginx_signing.key | apt-key add - && \
    apt-get update && apt-get install nginx && \
    apt-get upgrade -y && \
    apt-get clean

# 清除 apt cache
RUN rm -rf /var/lib/apt/lists

# 安装php ext 扩展
RUN docker-php-ext-install iconv sockets mbstring mysqli pdo pdo_mysql bcmath zip \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd intl

RUN apt-get clean \
    && apt-get autoclean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

# 配置php.ini文件
RUN echo "\

#copy file

COPY . /var/www
# 拷贝nginx config file
# 您的nginx 配置文件
COPY ./docker_conf_nginx_app.conf /etc/nginx/conf.d/site.conf

WORKDIR /var/www/
# 设置laravel/lumen storage 777 权限
RUN chmod 777 -R /var/www/storage

# 使用composer 安装laravel/lumen php 依赖
RUN composer install --no-autoloader --no-scripts --no-dev
RUN composer install --optimize-autoloader --no-dev


# Redirecting log outputs to stdout
#RUN ln -sf /dev/stdout /var/log/nginx/access.log \
#    && ln -sf /dev/stderr /var/log/nginx/error.log
    
# 自定义需要暴露的端口

STOPSIGNAL SIGTERM
# 启动php-fpm 和nginx 服务
CMD ["sh","-c","php-fpm && nginx -g \"daemon off;\""]

2. Docker-Composer(lnmp+redis)

docker-composer 文件最佳适用场景是 lnmp+redis的开发环境 https://github.com/mojocn/docker-lnmp

docker-lnmp
|----/build                  镜像构建目录
|----/work                   持久化目录
|--------/components/        组件库
|------------/component      组件,包括了数据,配置文件,日志等持久化数据
|-----------------/config    组件的配置目录
|-----------------/log       组件的日志目录
|--------/wwwroot            WEB 文件目录
|----/.env-example           配置文件
|----/docker-compose.yml     docker compose 配置文件
