:push does work, because it does not receive credentials from Credentials Store, when .docker/config.json doesn't store them.

[tobiashochguertel]

When I want to push my images to my private registry, I get an error, because there are no basic auth credentials provided.

with docker push ... from a terminal it works.

I also checked my .docker/config.json Configuration, an I was surprised that I can successfully push to my private registry without having the auth credential informations in the config.json file.

$ cat .docker/config.json
{
	"auths": {
		"dgroup.nexus3.h12.de.abc.com": {},
		"dprivate.nexus3.h12.de.abc.com": {}
	},
	"HttpHeaders": {
		"User-Agent": "Docker-Client/19.03.5 (darwin)"
	},
	"credsStore": "desktop",
	"experimental": "enabled",
	"stackOrchestrator": "swarm"

A research where my credentials for mu private registry are stored, took me to the docker login documentation page, where I was reading that they are stored in an Credential Store.

Credentials store
The Docker Engine can keep user credentials in an external credentials store, such as the native keychain of the operating system. Using an external store is more secure than storing credentials in the Docker configuration file.

To use a credentials store, you need an external helper program to interact with a specific keychain or external store. Docker requires the helper program to be in the client’s host $PATH.

This is the list of currently available credentials helpers and where you can download them from:

D-Bus Secret Service: https://github.com/docker/docker-credential-helpers/releases
Apple macOS keychain: https://github.com/docker/docker-credential-helpers/releases
Microsoft Windows Credential Manager: https://github.com/docker/docker-credential-helpers/releases
pass: https://github.com/docker/docker-credential-helpers/releases

CONFIGURE THE CREDENTIALS STORE
You need to specify the credentials store in $HOME/.docker/config.json to tell the docker engine to use it. The value of the config property should be the suffix of the program to use (i.e. everything after docker-credential-). For example, to use docker-credential-osxkeychain:

{
"credsStore": "osxkeychain"
}

If you are currently logged in, run docker logout to remove the credentials from the file and run docker login again.

Can we get this supported with dobi?

I'm running into the same issue as well. I did a little bit of digging and found that this function is delegated to the docker client lib here. Assuming that your .docker/config.json is in your HOME or DOCKER_CONFIG env var directories (the respective env var itself is set) it should in theory work (for reference). I'll dig little further tomorrow when I get the chance.
