    webserver:
      image: nginx:alpine
      container_name: jm-php7-2-webserver
      working_dir: /application
      volumes:
          - /var/www/html:/application
          - /var/log/nginx:/var/log/nginx
          - /var/www/docker/nginx+php/nginx/nginx.conf:/etc/nginx/conf.d/default.conf

    php-fpm:
      build: /var/www/docker/nginx+php/php7.2
      container_name: jm-php7-2-php-fpm
      working_dir: /application
      volumes:
        - /var/www/html:/application
        - /var/www/docker/nginx+php/php7.2/php-ini-overrides.ini:/etc/php/7.2/fpm/conf.d/99-overrides.ini

说明： webserver就是nginx镜像生成的容器服务

php-fpm就是php服务

volumes是宿主服务器的文件挂载到容器中的文件路径，以：分割，比如将主机的/var/www/html挂载到容器的/application目录

php-fpm镜像Dockfile

文件位置：/var/www/docker/nginx+php/php7.2/Dockerfi

FROM phpdockerio/php72-fpm:latest
WORKDIR "/application"

# Fix debconf warnings upon build
ARG DEBIAN_FRONTEND=noninteractive

# Install selected extensions and other stuff
RUN apt-get update \
    && apt-get -y --no-install-recommends install  php7.2-mysql php-redis php7.2-gd php-yaml \
    && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

nginx.conf配置

server {
    listen 80 default;

    client_max_body_size 20M;

    access_log /var/log/nginx/docker-demo.access.log;


    root /application/docker-demo;
    index index.html index.php;

    if (!-e $request_filename) {
        rewrite ^.*$ /index.php last;
    }

    location ~ \.php$ {
        fastcgi_pass php-fpm:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PHP_VALUE "error_log=/var/log/nginx/docker-demo.log";
        fastcgi_buffers 16 16k;
        fastcgi_buffer_size 32k;
        include fastcgi_params;
    }

}

注意：fastcgi_pass php-fpm:9000，这里的php-fpm对应的是docker-compose.yml里配置的php-fpm服务

php.ini覆盖设置

文件位置：/var/www/docker/nginx+php/php-ini-overrides.ini

upload_max_filesize = 20M
post_max_size = 20M
display_errors = On

关于日志

nginx日志

volumes配置中挂载了日志映射

- /var/log/nginx:/var/log/nginx

可以直接在主机中/var/log/nginx中查看ngxin容器的相关日志，一般php的错误日志，在php.ini中开启display_errors和log_errors，及error_log设置对应日志文件路径情况下，当前nginx版本也会记录php的错误日志信息

php日志

当然也可以通过Docker-compose logs来查看容器服务的一些日志

比如：

# 以下可以查看php-fpm容器的日志输出

sudo docker-compose logs -f php-fpm

实际上docker镜像将access.log和error.log分别软连接到了标准输出和标准错误，所以你能在docker logs中看到输出

参考：

https://docs.docker.com/compose/reference/logs/

https://segmentfault.com/q/1010000011411966

创建并启动容器

sudo docker-compose up
或者 
sudo docker-compose up -d

-d 表示在后台运行 如果docker-compose.yml中配置的镜像或容器服务不存在，则docker-compose会拉取镜像或根据自定义的Dockerfile生成新的镜像，并run对应容器

示例，可以忽略跳过

phpdockerio/php72-fpm镜像是nginxphp_php-fpm的基础镜像，通过基础镜像，配置Dockerfile生成新的镜像nginxphp_php-fpm镜像。

jm@ubuntu:/var/www/docker/nginx+php$ sudo docker ps

项目文件

nginx配置root为：/application/docker-demo，且将主机/var/www/html挂载到/application，所以我们/var/www/html/docker-demo建立项目文件：

jm@ubuntu:/var/www/html/docker-demo$ tree
.
├── index.html
└── index.php

index.html


from nginx docker.html

index.php

phpinfo();

测试

访问　http://192.168.8.130:8081

输出：

from ngxin docker.html

访问 http://192.168.8.130:8081/index.php

输出：

PHP Version 7.2.26-1+ubuntu18.04.1+deb.sury.org+1

修改配置

如果修改了docker-compose.yml的配置，那需要3步才能生效

#在docker-compose.yml当前目录下

sudo docker-compose stop
sudo docker-compose rm
sudo docker-compose up

如果没有生效，建议在up之前重启docker服务
