How to push the image to hub.docker.org (Lab 7.1)

Hello, the document is a little short on how to do a push image in hub.docker.com.
Why now is difference? docker have made some change and limitation for normal users, maybe for the demand or something else (i didn't dig into this).
So let's go to the main topic
In the labs, we will be making a push to our repository on hub.docker.com, but will fail with the next error: denied: requested access to the resource is denied
This happen because in the direct push with the lfstudent hostname/username, is not our username account on hub.docker.com.
To be a little more clear, the part of a docker repository is the next:
first username lfstudent/second image_name:third tag
so doing a docker image push lfstudent/alpine:training
will fail because our user is not lfstudent, it is the one you assign when creating the account on hub.docker.com.
So you need to follow the next steps:
$USERNAME_HUB.DOCKER.COM => Is the username account you created on hub.docker.com
- After login
docker login
docker tag lfstudent/alpine:training $USERNAME_HUB.DOCKER.COM/alpine:training
docker image push $USERNAME_HUB.DOCKER.COM/alpine:training
- visit the repository page of hub.docker.com

For the next Labs, i recommend that replace lfstudent with you hub.docker.com username, if there is more push

Hi @devdorrejo,
Thank you for your feedback. The exercise assumes the existence of such an account, the reason why no password is actually provided:
