docker push 命令
1.查询镜像id、或者名称
docker images
2.打标签
docker tag nginx-dev xxx/nginx-dev-copy:v1
nginx-dev:为容器名称(也可以是容器id)
xxx: 为 https://hub.docker.com/ 自己注册的用户名
nginx-dev-copy: 为镜像名称
v1:为版本号
3.推送远程仓库
docker push xxx/nginx-dev-copy:v1
xxx: 为 https://hub.docker.com/ 自己注册的用户名
注意:如果不打标签直接推送镜像到远程仓库是会失败的。
错误信息如下:
The push refers to repository [docker.io/xxx/nginx]
An image does not exist locally with the tag: xxx/nginx
[ custom]# docker tag nginx-dev /nginx-dev-copy:v1
Error parsing reference: "/nginx-dev-copy:v1" is not a valid repository/tag: invalid reference format
