Docker Authentication Failure


(Rajsekhar) #1

HI All. i would like to push the image into docker’s hub.
For that i have followed the following steps:
1)docker login
O/P: Login Succeded
2)docker push imagename
O/P:Authentication failure
to resolve this error, i have followed some blogs . And one of the solution was to modify the credentials in ~/.docker/config.json file. I have checked the config.json file . In this file, already the modification as suggested by people from blog its already there. So no need of modification of the file.
But still the error persists like "Authentication Failure"
Friends please help me on this. Its really urgent

I had been running into this same problem for a couple of weeks. All blog posts are old and not very helpful.

So far I have followed the examples of adding repos to the config.json, deleting and recreating the config and changing my password.

Now I am getting Error: Status 403 trying to pull repository darkmane/showcase: ““The Repository is Locked, access denied””. Any hints?

I’m trying to push from Mac OS, docker version 1.12 to a private repo on

Deleting and recreating the repo solved the issue.
