ADD dist.tar.gz /usr/share/nginx/html/
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

docker build -t myNginx:v1 . -f ./Dockerfile-web

docker images

docker run -d -p 85:80 --name myNginxV1 myNginx:v1               ## 使用新镜像创建容器 

docker start myNginxV1

docker ps

docker stop myNginxV1

docker rm myNginxV1

docker exec -it myNginxV1  /bin/sh

docker tag myNginx:v1 xxx.xxx.xxx.xxx/myNginx:v1
docker push xxx.xxx.xxx.xxx/myNginx:v1
