刚刚入坑,第一次push镜像失败,

原因1:命令内容无帐号信息

E:\docker\jdk8>docker push ubuntu:16-jdk8
The push refers to a repository [docker.io/library/ubuntu]
d4bd1dfba68a: Preparing
7f7a065d245a: Preparing
f96e6b25195f: Preparing
c56153825175: Preparing
ae620432889d: Preparing
a2022691bf95: Waiting
denied: requested access to the resource is denied

原因2: 本地镜像名无帐号信息

E:\docker\jdk8>docker push xuming9/ubuntu:16-jdk8
The push refers to a repository [docker.io/xuming9/ubuntu]
An image does not exist locally with the tag: xuming9/ubuntu

修改办法,将本地镜像名增加帐号信息

E:\docker\jdk8>docker tag c46fc7b6c818 xuming9/ubuntu:16-jdk8

重新push

E:\docker\jdk8>docker push xuming9/ubuntu:16-jdk8
The push refers to a repository [docker.io/xuming9/ubuntu]

tip: 有的网友说是版本太低,别听他们的,害我重装了docker麻烦死了
