Docker for Windows: Authentication issue with docker run but not docker login

I am running Docker for Windows on a Windows 2016 Server and have an issue when pulling images from registry.
As suggested I do a “docker login” before using docker on my Windows and the authentication work fine - I get a “Login succeeded”.
But when I do a “docker pull” I am asked to provide the credentials again which results in an “Error response from daemon: unauthorized: authentication required”

PS C:\Users\lasombraaa> docker pull iis
Using default tag: latest

Please login prior to pull:
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username (lasombraaa):
Password:
Error response from daemon: unauthorized: authentication required

same for “docker run”

PS C:\Users\lasombraaa> docker run powershell
Unable to find image 'powershell:latest' locally
C:\Program Files\Docker\docker.exe: Error response from daemon: unauthorized: authentication required.
See 'C:\Program Files\Docker\docker.exe run --help'.

The %USERPROFILE%.docker\config.json exists and I already deleted it and did a login again.

{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "xxxxxxxxxxxxx"
                }
        }
}

Interestingly, if I use microsoft specific package I do not have an authentication error but rather “image operating system “linux” cannot be used on this platform.”

PS C:\Users\lasombraaa> docker run microsoft/powershell
Unable to find image 'microsoft/powershell:latest' locally
latest: Pulling from microsoft/powershell
C:\Program Files\Docker\docker.exe: image operating system "linux" cannot be used on this platform.
See 'C:\Program Files\Docker\docker.exe run --help'.

Can somebody explain me what happens?

Some problems:

  • There’s no iis image. You’re probable looking for microsoft/iis.
  • There’s no powershell image. To run a powershell prompt in a Docker container, run: docker run -ti microsoft/nanoserver powershell

@lasombraaa: You’re seeing “Error response from daemon: unauthorized: authentication required” because you’re attempting to pull images that (as @friism observed) don’t exist. The error message from Docker 1.12.2 is confusing, which is bad. But Docker 1.13.0 does better (“Error response from daemon: repository iis not found: does not exist or no pull access”), which is good!

Thanks @friism and @noahtreuhaft for your answers. Yes the message is very confusing and a better error message is welcome. Looking forward to 1.13.0

I was using a suggested navigator password, and tried all the solutions but didn’t work.
I deleted my accound, and created a new, using a more easy password, avoiding certain spechial chars, and worked.
