docker unauthorized authentication required - upon push with successful login

Question

While pushing the docker image (after successful login) from my host I am getting "unauthorized: authentication required".

Details below.

-bash-4.2# docker login --username=asamba --email=anand.sambamoorthy@gmail.com

WARNING: login credentials saved in /root/.docker/config.json

*Login Succeeded*

-bash-4.2#

-bash-4.2# docker push asamba/docker-whale

Do you really want to push to public registry? [y/n]: y

The push refers to a repository [docker.io/asamba/docker-whale] (len: 0)

unauthorized: authentication required

• Docker version: 1.9.1 (both client and server)

• http://hub.docker.com has the repo created as well (asamba/docker-whale).

The /var/log/messages shows 403, I dont know if this docker. See below.

Answer 1

I also had the same issue.This is how I resolve it.

Step 1: log in to docker hub

docker login --username=<user username> --email=<user email address>

Step2: create a repository in the docker hub. let's say "mysqlserver:sql".

docker push <user username>/mysqlserver:sql

For docker version 17 use

docker login -u username -p password
