Harbor robot account: Error response from daemon: unauthorized: authentication required

Question

I'm always getting:

Error response from daemon: Get "https://myregistry.example.com/v2/": unauthorized: authentication required

When trying to login with:

docker login --username robot$myproject+myrobotaccount myregistry.example.com

Answer 1

Quote the robot username on Linux:

docker login --username 'robot$myproject+myrobotaccount' myregistry.example.com

But, do NOT quote the username on Windows

docker login --username robot$myproject+myrobotaccount myregistry.example.com
