Private Docker Registry Authentication Not Propagated to Remote Environments

[AndreaF17]

I’m trying to pull images from a private Docker registry using Dockhand.
The registry credentials are configured globally in the Dockhand management UI, and image pulls work correctly on the host where Dockhand itself is running.
However, when deploying or pulling the same image on remote hosts/environments managed by Dockhand, I consistently get:

authentication required

What I Expected

I expected the registry credentials configured globally in Dockhand to also be used by remote environments/hosts.

Current Behavior

• Works on the Dockhand host
• Fails on remote environments
• Error: authentication required

Question

Is this the expected behavior?
Do registry credentials need to be configured individually on each remote host/environment, even if they are already defined globally in Dockhand?

@jotka how should this work?
Is it explained in the Dockhand manual maybe?

hi @AndreaF17 any debug logs from hawser? I think it's this case #1145

[AndreaF17]

I got no errors on the hawser side, i also run the suggested script from that issue but it seems to be alright here is some screenshots:

• hawser logs

• docker logs (hawser host)

• Dockhand logs

• Script checker

I am sure that the credentials are correct because on the host running dockhand everything works.

Thanks for your time!

the expected behavior is credentials are propagated to remote hawser. there is no need to authenticate on every remote host manually.

Did you have any updates, or am i missing something?

[AndreaF17]

From testing i confirm that is probably a bug of dockhand.
If i create a deployment via github dockhand is not able to pull the image. But if i pull it from the container section and than deploy the deployment works.
Do i need to create a detailed issue or is enough?
