errors downloading the container

[janetrbarclay]

Hi - I'm getting the following error message when I try to download the container for the short course:

$ docker pull metsi/ats-short-course:latest
error during connect: This error may indicate that the docker daemon is not running.: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/images/create?fromImage=metsi%2Fats-short-course&tag=latest": open //./pipe/docker_engine: The system cannot find the file specified.

Does anyone have suggestions of what to try?

If I try to open Docker Desktop from the start menu, I get an error that access is denied because I'm not in the "docker-users" group.

I'm working on a windows machine and just installed docker desktop this afternoon.

I don't have administrative rights to my computer, but could reach out to our IT specialist if that is needed.

Thanks in advance for any suggestions!

PS I tried to post to the users group using the link from the email but got a message that the group doesn't exist or I don't have permission to post there

Can you tell us what type of system you are on? (my bad, I see you said you are on Windows).

You likely needed administrative rights to install Docker on Windows, did someone else install Docker for you? It does look like you need to be added to the "docker-users" group by your IT specialist at a minimum. But if they can give you admin privileges that would make your life easier as issues may keep coming up.

And can you verify that docker is running? For example, what happens when you type

docker info

at the command line?

I'm on a windows laptop (running 64-bit windows 10 Enterprise ver 1909). I have the processor info if that would be helpful at all.

Here's the output of docker info:

It does look like docker is not running. But you probably need to be in the docker-users group and/or get admin permissions so it would be best to get help from whomever administers your computer.

I'm not sure how it looks on windows by on mac there is a little docker icon that you can click on to get status, restart, etc. and run the docker desktop. Is there a similar icon on your tool bar or something?

[janetrbarclay]

I don't see an icon (but I did uncheck the box to add a desktop icon, though that doesn't usually prevent icons in the system tray).

Is the docker-users group something that is set-up within the windows users or once docker desktop is opened?

[janetrbarclay]

I just found this info on how to add the docker-users group in the docker docs. I'll touch base with my IT person and let you know if this solves it.

Adding my windows user account to the docker-users group (following the instructions in the link above) largely solved the issue. The only addition thing I had to do (after installing WSL 2 as noted) was slightly modify the command to check the version (adding winpty at the beginning)

winpty docker run -it --rm metsi/ats-short-course:latest ats --version

Thanks for your help!!
