Docker 容器镜像推送到Hub Docker

1.把容器制作成镜像
//REPOSITORY: mynginx , TAG:v1.0
docker commit -m="nginx测试环境" -a="read" 8e82a3116d76 mynginx:v1.0

2.将你想要上传的镜像打标签
//bbf50057aab1 为IMAGE ID
//read2020/my-private-repo 为hub docker的地址
//mynginx 为TAG名称
docker tag bbf50057aab1 read2020/my-private-repo:mynginx

3.推送镜像到hub docker
docker push read2020/my-private-repo:mynginx

4.获取远程镜像库文件
//read2020/my-private-repo 为hub docker的地址
//mynginx 为TAG标签名称
docker pull read2020/my-private-repo:mynginx
