problem:
When released mirroring, follow the tutorial executed, without success, search the next, find a solution, and record it.
denied: requested access to the resource is denied
Solution:
1. The first lists all mirrors
docker images
2. To publish the image change to your account name. My account name: shen6409175
docker tag ubuntu shen6409175/ubuntu
3. Mirror publish again
docker push shen6409175/ubuntu
4. Re-view mirror list
docker images
5. Review the image files under their own account
