映射docker搭建

Posted 2020-12-28 zeoblog

安装docker参考 https://yeasy.gitbooks.io/docker_practice/content/install/ubuntu.html

拉取ubuntu16.04 作为基本镜像
```
docker pull ubuntu:16.04
```

建个空目录 ，创建Dockerfile
```
# vi Dockerfile

FROM ubuntu:16.04

RUN apt update && apt install -y
nginx  
php  
php-mysql  
php-memcached  
php-msgpack
php-mbstring
php-dom  
php-zip
php7.0-dev
composer
wget  
unzip
re2c
libgearman-dev
# 删除apt缓存
&& rm -rf /var/lib/apt/lists/*
# 删除nginx默认配置
&& rm -rf /etc/nginx/sites-enabled/default
# 创建默认的日志目录
&& mkdir -p /opt/log
&& chown www-data /opt/log -R
COPY be-report /etc/nginx/sites-enabled

RUN mkdir -p /tmp/install
&& cd /tmp/install
&& wget https://github.com/wcgallego/pecl-gearman/archive/master.zip
&& unzip master.zip
&& cd pecl-gearman-master
&& phpize
&& ./configure
&& make install
&& echo "extension=gearman.so" > /etc/php/7.0/mods-available/gearman.ini
&& phpenmod -v ALL -s ALL gearman
&& php -m | grep gearman
ENTRYPOINT service nginx start && service php7.0-fpm start && /bin/bash
EXPOSE 80
```

创建默认的nginx配置，文件名be-report
```
# vi be-report

server {
listen 80;
server_name _;
root /var/www/html/be-report/public/;
index index.php;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

location ~ ^(.+.php)(.*)$ {
alias /var/www/html/be-report/public/;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_read_timeout 9999999999;
fastcgi_split_path_info ^(.+.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $DOCUMENT_ROOT$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $DOCUMENT_ROOT/$fastcgi_script_name;
include fastcgi_params;
}

location / {
rewrite ^(.*)$ /index.php/$1 last;
}
}
```
从Dockerfile创建镜像，镜像名为 be-report
```
docker build -t be-report .
```
从镜像运行容器
```
#/home/xj3hj2/docker/ 需根据代码位置调整
docker run -it -p 8054:80 -v /home/xj3hj2/docker/be-report:/var/www/html/be-report -v /opt/wwwroot/conf/:/var/www/conf/ be-report /bin/bash

# -p 8054:80 将本地的8054映射到容器的80端口
# -v 本地目录:容器目录 将本地的代码目录映射到容器中，默认可读可写
```
#运行后进入了容器的bash 
```
cd /var/www/html/be-report && composer install 
```
结束后，ctrl+p 再 ctrl+q 退出容器

退出容器后在本机配置nginx转发
sites-enabled/default 的
server dev.tob.ifchange.com 那一段
里增加：
```
location /v2/ {
proxy_pass http://report.ats.v2.dev.ifchange.com;
proxy_set_header Host $http_host;
}
```
conf.d/upstream.conf里增加
```
upstream report.ats.v2.dev.ifchange.com{
server localhost:8054;
}
```
测试：
http://dev.tob.ifchange.com/v2/account/cache

备注：
```
#查看所有容器，运行和未运行的
docker ps -a
#容器启动 停止
docker start/stop 容器名
#容器删除
docker rm 容器名

#查看所有镜像
docker images
#删除镜像
docker rmi 镜像名 //需要没有关联的容器

#tob-resume-service
cp bootstrap/autoload.php.example bootstrap/autoload.php
编辑 bootstrap/autoload.php 最前面 define(‘ENV‘, ‘dev‘)
```
