0.说明
1.Jenkins必要插件、配置、Job创建、Gogs配置等参考测试环境步骤
2.生产环境Django项目一般nginx+uwsgi+django部署；
3.项目容器介绍
容器1:Django+uwsgi作为核心应用程序，处理客户端的请求；
容器2:Nginx反向代理服务并处理静态资源请求。
4.流水线处理过程参考框架图如下：
1）用户向Gogs推送(push)代码，webhook触发jenkins中项目job;
2）项目job，从Gogs中拉取代码并通过Publish Over SSH传送至Docker服务器；SSH远程通过Docker-compose build两个容器，并启动两个容器。
1.Publish Over SSH远程执行过程
#删除nginx容器
docker inspect local_cmdb_nginx_1 -f '{{.Name}}' > /dev/null
if [ $? -eq 0 ] ;
then
echo "docker local_cmdb_nginx_1 exist" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
docker rm -f local_cmdb_nginx_1
else
echo "docker local_cmdb_nginx_1 don't exist" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
fi
#删除django容器
docker inspect local_cmdb_django_1 -f '{{.Name}}' > /dev/null
if [ $? -eq 0 ] ;
then
echo "docker local_cmdb_django_1 exist" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
docker rm -f local_cmdb_django_1
else
echo "docker local_cmdb_nginx_1 don't exist" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
fi
# 由于向Docker容器中拷贝文件会影响递归结构，所以需要将项目目录先压缩
cd /root/
ll local_cmdb
if [ $? -ne 0 ]; then
echo " project push succeed" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
fi
tar -czvf local_cmdb.tar.gz local_cmdb
echo `pwd`
cd /root/local_cmdb
mv -f /root/local_cmdb.tar.gz ./
#构建容器
docker-compose build
if [ $? -ne 0 ]; then
echo " container build failed" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
fi
#启动容器
docker-compose up -d
if [ $? -ne 0 ]; then
echo " container up failed" `date +%Y%m%d%H%M%S`>> /var/log/jenkins.tmp
fi
2.Docker-compose部署项目
项目大致的目录结构
├── config
│ ├── nginx.conf nginx配置文件
├── docker-compose.yml compose yml文件
├── Dockerfile_django django+uwsgi容器Dockerfile
├── Dockerfile_nginx nginx容器Dockerfile
├── local_cmdb

1)docker-compose.yml文件
version: "2.3"
