git 添加 origin

 git remote add  origin git@github.com:mengkaibulusili/centos7.git

dockerfile

容器运行时应该尽量保持容器存储层不发生写操作,对于数据库类需要保存动态数据的应用,其数据库文件应该保存于卷(volume)中

volume 挂载卷的位置

令 容器2 挂载 容器1 的数据内容
docker run --name <容器2> --volumes-from <容器1名称>

封装脚本,包装自启动容器

先创建一个数据卷 容器

cat << EOF > DockerfileDataVolum 
FROM alpine
COPY shopServer /root/shopServer

VOLUME /root/shopServer

CMD ["/bin/bash"]
docker build -f DockerfileDataVolum  -t registry.cn-hangzhou.aliyuncs.com/mkmk/centos:VolumeData .

创建应用容器 基于 nginx django 容器

阻塞 容器推出的小细节

/root/shopServer/startServer.sh 内容

cd /root/shopServer && \
source /root/.bashrc && \
pip3 install -r requirements.txt && \
uwsgi -x /root/shopServer/shopServer.xml && \
nginx -t  -c /root/shopServer/nginx/myNginx.conf && \
nginx  -c /root/shopServer/nginx/myNginx.conf 
# tail -f 可以阻塞 容器执行网命令退出
tail -f /dev/null
cat << EOF > shopServerDF
FROM registry.cn-hangzhou.aliyuncs.com/mkmk/centos:Py36Nginx

CMD ["/bin/bash","/root/shopServer/startServer.sh"]
docker build -f shopServerDF -t registry.cn-hangzhou.aliyuncs.com/mkmk/centos:shopServer .

使用数据容器

//新建数据容器但是不用运行
docker create --name djangoVolume  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:VolumeData

docker stop centos7base  | docker rm centos7base 

//运行并 挂载数据容器
docker run -d --name centos7base -p 13000:3000 -p 15000:5000  --volumes-from djangoVolume    --privileged=true  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:shopServer

配置 nginx uwsgi

nginx -t -c  /root/shopServer/myNginx.conf
nginx -c  /root/shopServer/myNginx.conf
查看服务是否正常启动
ps -ef|grep uwsgi 

暂停服务器脚本

nginx -s stop
pkill -9 uwsgi
pkill -9 python3

详解前后端 分离部署 nginx 配置

           uwsgi_param UWSGI_CHDIR /root/shopServer/; #项目路径
        }

        # 静态资源路径 也可以不配置, 
        #因为我们使用的是 webpack 打包的应用程序
        # 只要部署了 build 文件即可
        location /static/ {
        alias /root/shopServer/templates/static/; #静态资源路径
        }

        location / {
           index index.html;
           alias /root/shopServer/build/;

centos7 镜像

配置中文编码

  && yum -y install gcc automake autoconf libtool make wget \
  && yum -y install kde-l10n-Chinese telnet  \
  && yum -y install glibc-common \
  && yum clean all \
  && localedef -c -f UTF-8 -i zh_CN zh_CN.utf8   \

ENV LC_ALL  zh_CN.UTF-8
ENV LANG    zh_CN.UTF-8
cd centos7
docker build -t  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:base7 .

使用

 docker run -d --name centos7base -p 13000:3000 -p 15000:5000  --privileged=true registry.cn-hangzhou.aliyuncs.com/mkmk/centos:base7 init

挂载数据卷容器

先创建一个数据卷容器

构建python3612镜像

docker build -f DockerfilePy3612  -t  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:base7Py3612 .

使用 python3612

docker stop centos7base  | docker rm centos7base 


 docker run -d --name centos7base -p 13000:3000 -p 15000:5000  --privileged=true registry.cn-hangzhou.aliyuncs.com/mkmk/centos:base7Py3612 init 

设置代理

export http_proxy="http://192.168.1.6:7890/"
export https_proxy="http://192.168.1.6:7890/"

构建命令

保证自己的网络可用

docker build -f DockerfilePy3612Nginx  -t  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:Py36Nginx .

使用

docker stop centos7base  | docker rm centos7base 

docker run -d --name centos7base -p 13000:3000 -p 15000:5000  --privileged=true  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:Py36Nginx  init 

进行数据卷的挂载

先创建一个数据卷 容器

cat << EOF > DockerfileDataVolum 
FROM alpine
COPY shopServer /root/shopServer

VOLUME /root/shopServer

CMD ["/bin/bash"]
docker build -f DockerfileDataVolum  -t registry.cn-hangzhou.aliyuncs.com/mkmk/centos:VolumeData .

新建应用容器挂载数据

//新建数据容器但是不用运行
docker create --name djangoVolume  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:VolumeData

docker stop centos7base  | docker rm centos7base 

//运行并 挂载数据容器
docker run -d --name centos7base -p 13000:3000 -p 15000:5000  --volumes-from djangoVolume    --privileged=true  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:Py36Nginx  init 

构建容器

 docker build -f DockerfilePy3612Nginx  -t  registry.cn-hangzhou.aliyuncs.com/mkmk/centos:Py36Nginx .

进入容器后启动服务

 pip3 install -r requirements.txt && python3 manage.py runserver 0.0.0.0:5000
