docker 镜像构建实践pagekit CMS(docker hub/docker cloud)

需要的网站如下:

Docker Hub: https://hub.docker.com/

Docker Cloud: https://cloud.docker.com

github: https://github.com/

这篇博客只是一次docker 镜像的自动构建,关于Dockerfile的编写,上下文路径等请提前学习.

pagekit CMS: 开源的php内容管理系统

环境:PHP,Web(Nginx),PHP扩展(php5-fpm php5-cli php5-json php5-mysql php5-curl) 基本服务组件(ca-certificates)

思路: 将编写的文件push到github上的仓库,在docker hub 或docker cloud上设置与github的hook并触发自动构建.

代码下载:[email protected]:xiaer1921/docker_pagekit.git

一.Docker Hub自动构建

1. 配置Docker Hub,右上角头像菜单->Settings->Linked Accounts & Services->Link Github.

2.右上角Create->Create Automated Build->Link Account Github->选择github 仓库

3.创建后Build Settings可以看到Branch选择,就能理解,触发会根据你的设置对你更改的github分支进行自动构建,Build Details可以看到构建历史.Tags查看创建成功的镜像.

二.Docker cloud自动构建

1.Repositories->创建一个仓库,Link to Github后,Builds->Configure Automated Builds->Build Text为上下文路径,Dockerfile location是相对上下文来说的,一定要选Autobuild.

2.Timeline可浏览构建历史和日志.

在自动构建完成以后,docker会给邮箱里发送构建信息.

三.

Dockerfile文件代码:

FROM ubuntu:trusty  

RUN apt-get update && \ 
    apt-get -y install \ 
    nginx \ 
    unzip \ 
    wget \ 
    ca-certificates \ 
    php5 php5-fpm php5-cli php5-json php5-mysql php5-curl 

ENV PAGEKIT_VERSION 1.0.2 
RUN mkdir /pagekit 
WORKDIR /pagekit 
VOLUME ["/pagekit/storage", "/pagekit/app/cache"] 

RUN wget https://github.com/pagekit/pagekit/releases/download /$PAGEKIT_VERSION/pagekit-$PAGEKIT_VERSION.zip -O /pagekit/pagekit.zip && \ 
    unzip /pagekit/pagekit.zip && rm /pagekit/pagekit.zip 

ADD /pagekit/nginx.conf /etc/nginx/nginx.conf 

RUN chown -R www-data:/pagekit &&\
    apt-get autoremove wget unzip -y && \ 
    apt-get autoclean -y && \ 
    apt-get clean -y && \ 
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* 

CMD ["sh", "-c", "service php5-fpm start && nginx"]

Nginx配置文件:

    location / { 
      try_files $uri $uri/ /index.php?$args; 
      index index.html index.htm index.php; 
    } 
    location ~ \.php$ { 
      try_files $uri $uri/ /index.php?$args;
      index index.html index.htm index.php; 
      include fastcgi_params; 
      fastcgi_index index.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; 
      fastcgi_param HTTP_MOD_REWRITE On; 
      fastcgi_pass unix:/var/run/ php5-fpm.sock; 
      fastcgi_split_path_info ^(.+\.php)(/.+)$; 
    } 
  } 
}

吐槽一句,写博客真的是耗时,想想一本书都看完了,才懒得写了一篇博客,<Docker从入门到实战>与<Kubernetes权威指南从Docker到Kubernetes实践全接触>相比,完全是小巫见大巫,慢慢来吧.
