docker build -t vitcloud-tomcat .2.3 启动容器
docker run -d -p 9090:8080 \

vitcloud-tomcat交互方式进入
docker exec -it 654c26bc7abb /bin/bash2.4 发布项目
由于做了卷挂载，我们字节在本地编写项目就可以发布了

9.1 将容器提交镜像 commit
docker commit 提交同期成为一个副本
# 命令和git原理类似
docker commit -m="提交的描述信息" -a="作者" 容器id 目标镜像名:[TAG]案例
docker commit -a="有勇气的牛排" -m="add webapps app" 48629b5a69d2 tomcat02:1.09.2 发布镜像 push
9.2.1 dockerhub
# 帮助
docker login --help
# 登录
docker login -u 用户名
# 给镜像添加tag --- 基于容器
docker tag d89b35c35d33 my/blog:1.0
# 推动自己的镜像到 DockerHub
docker push my/blog:1.09.2.2 阿里云
# 登录阿里云
docker login --username=***@qq.com registry.cn-zhangjiakou.aliyuncs.com
# 构建镜像
docker build -f ./Dockerfile -t my/blog:1.0 .
# 给镜像生成版本号
docker tag [ImageId] registry.cn-zhangjiakou.aliyuncs.com/my/blog:1.0
# 推送镜像
docker push registry.cn-zhangjiakou.aliyuncs.com/my/blog:1.0
# 拉取镜像
docker pull registry.cn-hangzhou.aliyuncs.com/my/blog:1.09.3 save
将镜像保存到本地
docker save -o centos7-python38_2.0.tar centos7-python38:2.0加载本地镜像
docker load -i centos7-python38_2.0.tar
