Unauthorized: authentication required Harbor

Question

I am facing the following issue.

I have a harbor private registry and i am trying to login through docker cli.

I am able to login successfully with: docker login <harbor_ip>. When i execute this command the cli is asking me for username and password and it logins successfully.

But when i try to login with the following command docker login -u <username> -p <password> <harbor_ip> i get the following error:

unauthorized: authentication required

Bear in mind i am using the same credentials.

Why this is happening?

Answer 1

when you are using haproxy or cdn infront of harbor to handle ssh termination, its important to set external_url in harbor.yml file.

it solved my problem

Answer 2

Please wrap your username and password with single quote

docker login -u '<username>' -p '<password>' <harbor_ip>
