Cannot push to ECR

Description

Cannot push images to ECR. I've tried using 1.3.3 and using docker-client version 8.10 per this old issue, but neither can connect to my docker client.

How to reproduce

1. set dockerfile.repository per ECR's required structure
2. provision the repo if needed: aws ecr create-repository --repository-name "$(mvn help:evaluate "-Dexpression=dockerfile.repository" -q -DforceStdout)"
3. use your ${ecr_name} in the command aws ecr get-login-password | docker login --username AWS --password-stdin "${ecr_name}"
4. mvn package
5. mvn dockerfile:push - fails
6. docker push "$(mvn help:evaluate "-Dexpression=dockerfile.repository" -q -DforceStdout):$(mvn help:evaluate "-Dexpression=dockerfile.tag" -q -DforceStdout)" - succeeds

What do you expect

mvn dockerfile:push succeeds whenever docker push would

What happened instead

push fails with error

I know this is an old Issue, but I ran into this today with 1.4.13 and spent too much time troubleshooting it.

TL;DR - updating .docker/config.json to use credsStore=ecr-login is easiest.
It also needs to have the registry in the auths section.

{
	"auths": {
                 "12345.dkr.ecr.us-east-2.amazonaws.com": {}
	},
	"HttpHeaders": {
		"User-Agent": "Docker-Client/18.09.0 (windows)"
	},
	"credsStore": "ecr-login"
}

I use the AWS Tools for PowerShell, but I suspect we have a similar problem. To authenticate I run:
Invoke-Expression -Command (Get-ECRLoginCommand -Region us-east-2).Command

My .docker/config.json was auto-generated when I logged in, with these contents after I deleted the file and let docker re-create it.

{
	"auths": {
		"12345.dkr.ecr.us-east-2.amazonaws.com": {}
	},
	"HttpHeaders": {
		"User-Agent": "Docker-Client/18.09.0 (windows)"
	},
	"credsStore": "wincred"
}

Pushing with this failed, so I ran maven with the -X flag for debug output and saw the call to docker-credential-wincred get.

Stepping through the plugin execution in an attached debug session I saw ConfigFileRegistryAuthSupplier.authFor try the https variant and fail because docker-credential-wincred doesn't have that registry, as confirmed with

echo https://12345.dkr.ecr.us-east-2.amazonaws.com | docker-credential-wincred get

Trying without the protocol works:

echo 12345.dkr.ecr.us-east-2.amazonaws.com | docker-credential-wincred get

The plugin then tried without the protocol (yay!), but because config.json has a stub entry for that name DockerConfigReader.authForRegistry returned the empty object with no auth info and never reached the credsStore piece.

These options don't work:

• add the https:// repository url to the auths section
• remove the auths section - the build process fails when DockerConfigReader.authForAllRegistries doesn't add the credsStore since hasAuths is now false
• add a stub entry to auths for a different name - the build fails since DockerConfigReader.authForAllRegistries only adds the credsStore for the registries named in the auths section

I believe these to be bugs:

• The build path works properly and uses the authForAllRegistries, but the push path doesn't do the same.
• DockerConfigReader.authForRegistry should check for empty auth and then fallback to credsStore
