Docker ImagePush失败，“没有基本身份验证凭据”

Question

I'm attempting to use the docker go-sdk to push an image to AWS ECR.

This is the code I'm using to push the image.

where tag = ".dkr.ecr.us-east-1.amazonaws.com/api:mytag"

func Push(c context.Context, tag string, credentials string) error {
    cli, err := client.NewClient(apiSocket, apiVersion, nil, apiHeaders)
    if err != nil {
        return err
    }
    fmt.Println(credentials)

    resp, err := cli.ImagePush(c, tag, types.ImagePushOptions{
        RegistryAuth: credentials,
    })
    if err != nil {
        panic(err)
    }

    io.Copy(os.Stdout, resp)
    resp.Close()

    return nil
}

But I keep getting this response:

{"status":"The push refers to repository [<id>.dkr.ecr.us-east-1.amazonaws.com/api]"}
{"status":"Preparing","progressDetail":{},"id":"23432919a50a"}

{"status":"Waiting","progressDetail":{},"id":"df64d3292fd6"}
{"errorDetail":{"message":"no basic auth credentials"},"error":"no basic auth credentials"}

Any ideas?

Notes:

• I've verified that the credentials string I'm passing in is a base64 encoded user:pass for the ECR registry.
• I've verified that the ECR credentials I'm getting are from the same AWS Region as where im attempting to push the image.

Answer 1

I found out in a GitHub comment that RegistryAuth actually needs to be a base64 JSON string with username and password fields. Ugh. This is undocumented in the Docker repository.

RegistryAuth = "{ \"username\": \"myusername\", \"password\": \"mypassword\", \"email\": \"myemail\" }

Relevant GitHub comment.

It is working for me now.
