git 添加 origin
镜像地址 git@github.com:mengkaibulusili/centos7.git
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

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/"
直接构建 nginx + py36

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
