#Docker：容器化应用
###定义数据库服务
```
version: '2'
services:
db:
image: mariadb:10.1
environment:
MYSQL_ROOT_PASSWORD: "root"
MYSQL_DATABASE: "app"
MYSQL_USER: "app"
MYSQL_PASSWORD: "123123"
volumes:
- db:/var/lib/mysql
volumes:
db:
driver: local
```
###测试数据库服务
```
docker-compose up -d
docker-compose exec db bash
mysql -u root -p
show databases;
create database test default charset utf8;
show databases;
exit
exit
docker-compose down
docker-compose up -d
docker-compose exec db bash
mysql -u root -p
show databases;
```
###定义PHP服务
```
version: '2'
services:
php:
image: php:7.0-fpm
volumes:
- ./app:/mnt/app
db:
image: mariadb:10.1
environment:
MYSQL_ROOT_PASSWORD: "root"
MYSQL_DATABASE: "app"
MYSQL_USER: "app"
MYSQL_PASSWORD: "123123"
volumes:
- db:/var/lib/mysql
volumes:
db:
driver: local
```
./app/phpinfo.php
```
<?php phpinfo(); ?>
```
###定义nginx服务
```
version: '2'
services:
web:
image: nginx:1.11.1
ports:
- "8080:80"
depends_on:
- php
volumes_from:
- php
volumes:
- ./images/nginx/config:/etc/nginx/conf.d
php:
image: php:7.0-fpm
volumes:
- ./app:/mnt/app
db:
image: mariadb:10.1
environment:
MYSQL_ROOT_PASSWORD: "root"
MYSQL_DATABASE: "app"
MYSQL_USER: "app"
MYSQL_PASSWORD: "123123"
volumes:
- db:/var/lib/mysql
volumes:
db:
driver: local
```
./images/nginx/config/default.conf
```
server {
listen 80;
server_name localhost;
root /mnt/app;
index index.php index.html index.htm;
location / {
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
```
./.env
```
COMPOSE_CONVERT_WINDOWS_PATHS=1
```
测试
```
docker-compose up -d
```

###创建自己的服务
现在我们在compose文件里面定义的服务用的都是现成的镜像，有时候我们需要去定制一下这些镜像。比如说去添加一下自己的配置，去安装新的模块等等。比如我想去修改一下PHP服务里面的一些配置，现在你可以看到它的 upload_max_filesize 它的值是2M
```
version: '2'
services:
web:
image: nginx:1.11.1
ports:
- "8080:80"
depends_on:
- php
volumes_from:
- php
volumes:
- ./images/nginx/config:/etc/nginx/conf.d
php:
build:
context: ./images/php
dockerfile: Dockerfile
volumes:
- ./app:/mnt/app
db:
image: mariadb:10.1
environment:
MYSQL_ROOT_PASSWORD: "root"
MYSQL_DATABASE: "app"
MYSQL_USER: "app"
MYSQL_PASSWORD: "123123"
volumes:
- db:/var/lib/mysql
volumes:
db:
driver: local
```
./images/php/Dockerfile
```
FROM php:7.0-fpm
MAINTAINER zhulinjie <zhulinjie_cool@126.com>
COPY ./config/php.ini /usr/local/etc/php/conf.d
```
./images/php/config/php.ini
```
memory_limit = 256M
post_max_size = 100M
upload_max_filesize = 100M
```
```
// 创建服务需要的镜像
docker-compose build
// 重新创建需要的服务
docker-compose up -d
```
通过浏览器访问：http://192.168.99.100:8080/phpinfo.php upload_max_filesize的值已经变为了100M
###安装PHP模块
./images/php/Dockerfile
```
FROM php:7.0-fpm
MAINTAINER zhulinjie <zhulinjie_cool@126.com>
RUN apt-get update && apt-get install -y libpng12-dev libjpeg-dev && rm -rf /var/lib/apt/lists/* && docker-php-ext-configure gd --with-png-dir=/usr --with-jpeg-dir=/usr && docker-php-ext-install gd pdo_mysql zip opcache
COPY ./config/php.ini /usr/local/etc/php/conf.d
COPY ./config/opcache-recommended.ini /usr/local/etc/php/conf.d
```
./images/php/config/opcache-recommended.ini
```
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
```
```
// 创建服务需要的镜像
docker-compose build
// 重新创建需要的服务
docker-compose up -d
```

###创建工具包容器
