I am going through a unexpected error. I am always getting the error "Error response from daemon: unauthorized: authentication required" whenever I am trying to pull microsoft/mssql-server-windows:2017-latest by using the blow command.
C:\Users\Administrator>docker pull microsoft/mssql-server-windows:2017-latest
Surprisingly I am able to login when I use docker login, I am not sure what I am missing here. I am also able to login to https://hub.docker.com/ with the credentials I have. The problem exists only when I try pull.
C:\Users\Administrator>docker pull microsoft/mssql-server-windows:2017-latest

I found out the reason. It was the problem with the repository name. I searched for
mmsqlin the hub.docker, there I could not find any repositories with the namemicrosoft/mssql-server-windows:2017-latestand I selectedmssql-server-windows-expressand run the pull command as below.docker pull microsoft/mssql-server-windows-expressAfter I enter my credentials it was pulling the repository as expected. It seems like we get this authorize error when the repository name is invalid.
