SOLVED Help Installing a Docker Image - Docker Login?

[yottabit]

I am trying to install debian:stable. I have tried various combinations in the SCALE UI for Image Repository / Image tag:

1. debian / latest
2. debian/debian / latest
3. debian/debian / stable

This latest attempt, as shown above, resulted in this error in the logs:

n/debian, repository does not exist or may require 'docker login': denied: requested access to the resource is denied" image="debian/debian:stable"

So maybe this is the right way to use those parameters, but do I have to provide login credentials to Docker.io to pull that image? I don't see any way to do so in the UI.

Any pointers?

Hi,

Never used scale here but from the log, it is pretty clear :

"Not continuing with pull after error: errors:
denied: requested access to the resource is denied
unauthorized: authentication required
"

So you need to authenticate before downloading from the repository you are using. Are you trying to pull from Docker Hub ? Another one ? Do you already have credentials for that repository ?

 

[yottabit]

Right, but there doesn't seem to be any place to add authentication to the docker setup in SCALE. I am assuming, as long as I have the repo and tag the way SCALE expects, that I have to login to Docker to download from that repo.

I think I found it: Manage docker images -> Pull Image.

I'll give it a try later, and then mark this as solved, if it works.

For now I can't even get builtin apps (Plex) to deploy. :-/

 

[yottabit]

I still have not been able to figure this out. I have entered my Docker.com username & password, but I still receive the `requested access to the resource is denied` message.

Any hints? Anyone can offer?

Are you using 2FA in your Docker account ? If you do, you need a special Application password for that.

Figured it out. Don't need user/pass for Docker. Just need to fix the image name to 'docker' only, which is a little confusing considering the tooltip for the Image Name field.
