I'm still getting the authentication error.
I understand the problem with naming. I thought we could create our own workspace, but we need to use one of the ones you created. So I've done that.
This is what I'm getting:
```
$ docker login docker.synapse.org
Username (username): username
Password:
Login Succeeded
$ docker push docker.synapse.org/synXXXXXX/dm-python-example
The push refers to a repository [docker.synapse.org/synXXXXXX/dm-python-example]

Created by Peter Brooks fustbariclation @ltang: I think we resolved this question elsewhere. (The issue was that you had to become a "Synapse Certified User" before being allowed to "docker push".) If you need further assistance to resolve this issue, please let me know. Hi, I'm experiencing the same problem, my project ID is syn7428675, what seems to be the problem? Please post the project ID (synxxx) that you are trying to push to. We will then investigate.
