I encounter same problem. Finally find out the tar file should be docker build context even with Dockerfile.

Here is my code,

package main

import (
    "log"
    "os"

    "github.com/docker/docker/api/types"
    "github.com/docker/docker/client"
    "golang.org/x/net/context"
)

func main() {
    dockerBuildContext, err := os.Open("/Users/elsvent/workspace/Go/src/test/test.tar")
    defer dockerBuildContext.Close()

    buildOptions := types.ImageBuildOptions{
        SuppressOutput: true,
        PullParent:     true,
        Tags:           []string{"xxx"},
        Dockerfile:     "test/Dockerfile",
    }
    defaultHeaders := map[string]string{"Content-Type": "application/tar"}
    cli, _ := client.NewClient("unix:///var/run/docker.sock", "v1.24", nil, defaultHeaders)
    buildResp, err := cli.ImageBuild(context.Background(), dockerBuildContext, buildOptions)
    if err != nil {
    log.Fatal(err)
    }
    defer buildResp.Body.Close()
}
