Failure to Push Docker Image to ECR w/ Docker Go SDK

Question

I'm using the docker client SDK for Go and I'm running to an issue with pushing images to my AWS ECR.

Here is the gist of my func

import (
    "github.com/docker/docker/api/types"
    dockerclient "github.com/docker/docker/client"
)
func doPush(target string) {
    envCli, err := dockerclient.NewEnvClient()
    if err != nil {
        panic(err)
    }

    rc, err := envCli.ImagePush(
        context.Background(),
        target,
        types.ImagePushOptions{})
    if err != nil {
        panic(err)
    }
    defer rc.Close()
}

My image is tagged something like [regid].dkr.ecr.us-east-1.amazonaws.com/demo:latest but I get the following error:

invalid reference format

If I remove the [:tag] from the image name, it works until I get a

Error response from daemon: Bad parameters and missing X-Registry-Auth: EOF

Answer 1

I had the same problem, and I solved it giving an arbitrary RegistryAuth to the docker push option.

So the following code works :

closer, err = dockerClient.ImagePush(context.Background(), privateTagName,
                                     types.ImagePushOptions{
                    All: true,
                    RegistryAuth:"123",
                })
if err != nil{
  panic(err)
}
io.Copy(os.Stdout, closer)
closer.Close()

I read in this post that giving any value to RegistryAuth could work.
