Docker run hello-world error

docker

(Vishwa) #1

Hi,

I’m just getting started with docker. I’m following the instructions specified here https://docs.docker.com/windows/step_one/

I installed docker (1.10.2) on windows 10 & ran docker run hello-world . But, I’m getting an authentication error while the tutorial doesn’t mentioned anything about it.

Here’s the message I received.

$ docker run hello-world Unable to find image 'hello-world:latest' locally docker: Error response from daemon: Authentication is required: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: unauthorized: incorrect username or password. See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.

I searched google & SO but couldn’t find anything exactly similar to this.

Thanks!

Try this:

  1. Open up shell in administrator mode
  2. Enter docker login
  3. Enter Docker ID & Password.
    4.Execute docker info
  4. Execute docker run hello-world.

This should work when you have already created Ducker ID. Get it here=>> https://cloud.docker.com/

I had the same problem. It turns out that the CLI (docker login) needs your USERNAME (not e-mail address), even though the e-mail address works for the docker web site or desktop UI.
