Docker Authentication required error when pulling image from dockerhub

Question

I am on Windows and trying to pull spcrapy-splash base image with powershell.

Command is : docker pull scrapinghub/splash

I have docker desktop running. And I did docker login and successfully logged in.

However every time I get this error on powershell: docker: unauthorized: authentication required.

I tried to modify .docker.config.json file with


{
    "auths": {
        "https://index.docker.io/v1/": {
            "auth": "XXX", 
            "email": "email@gmail.com"
        }
    },
    "credsStore": "desktop",
    "stackOrchestrator": "swarm"
}

I know auth is encoded username:password string. And I can login succesfully. So I cannot figure out why still keep getting authentication error. Is there something I am missing?

Docker Version is 20.10.5

can you close the terminal and login again and try pulling the image — Rohith V, May 12 '21 at 11:06
May not be a solution, but what about clearing the credsStore and stackOrchestrator — Rohith V, May 12 '21 at 11:15

Apparently, it was the Docker Desktop version problem. I Replaced latest with the current version and it worked.

For anyone who is struggling with authentication error, I suggest

check with the config file,

then update docker to the latest version.

Restart Docker and command line, run docker login

try again pulling or pushing.

Hi , I am facing the same issue while pulling an image.Shall i upgrade my docker version or docker desktop version or both.Please clarify – Gaurav Gupta Jun 12 '21 at 11:00
try to update docker desktop version first. Mine worked after that – bdemirka Jun 12 '21 at 11:16
That would mean downloading latest version from its official site,installing it(which would require admininistrative privilges which i dont have as its my official laptop).It can take days and i need kind of urgently to finish up a critical task – Gaurav Gupta Jun 12 '21 at 11:29

The docker I am using is the latest Version 3.4.0 and I just downloaded it yesterday and installed it. I tried installing splash using docker but it gave me authentication error. I have opened the config, please what is the latest configuration arrangement that works for it ?

I have the auth, it's just to get the right arrangement to make it work.

Please can you send the configuration that worked for you ?
