dockerfile 制作镜像

标签：cli   ffffff   try   cpu   off   yaml   config   tar.gz   删除   

以下是具体内容

#mkdir /root/dockerfile
#cd /root/dockerfile
#touch Dockerfile 
#mkdir nginx

制作dockerfile文件
root@<cc_172.16.0.2|~/dockerfile/nginx>:#cat Dockerfile 
#Centos?based?container?with?tengine2.2
FROM docker.io/centos
MAINTAINER  wbb-20181207 wbb@qq.com

#prepare java environment
ENV LD_LIBRARY_PATH /usr/local/luajit/lib:$LD_LIBRARY_PATH
ENV LUAJIT_INC /usr/local/luajit/include/luajit-2.0
ENV LUAJIT_LIB /usr/local/luajit/lib

#copy jdk tomcat to container
ADD nginx.tar.gz  /root/

RUN cd /root/nginx/ && sh ngxinstall.sh \             #nginx.sh安装脚本单独用脚本编写,下面有展示
&& ln -sf /dev/stdout /var/log/nginx/access.log \    #让nginx日志在k8s的web-ui里显示出来,如下图
&& ln -sf /dev/stderr /var/log/nginx/error.log

#private expose
EXPOSE 80 

#START NGINX
#ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]
CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]     一定要前台运行,不然k8s在deploy中无法创建成功

cd /root/dockerfile
docker build -t nginx:v4 .

安装过程部分截图

ngxinstall.sh 安装脚本,在dockerfile中引用,以下安装脚本最好先在1台机器测试好,没问题直接在dockerfile引用即可

制作nginx.sh的nginx安装脚本

k8s dashboard中显示的生成的nginx pod,

外网访问显示测试页

nginx日志在web-ui中显示,要在此显示日志,就必须在dockerfile中定义,不然是不是会显示的.因为k8s展示的日志是从/dev/stdout /dev/stderr 里获取的
