Question

我有以下代码从包含Dockerfile的.tar文件构建映像。

os.MkdirAll("configs/container",0755)
tar := new(archivex.TarFile)
tar.Create("configs/container/conf.tar")
tar.AddAll("configs/configdir", false)
tar.Close()

dockerBuildContext, err := os.Open("config/dns/conf.tar")
defer dockerBuildContext.Close()


buildOptions := types.ImageBuildOptions{
        Context:    dockerBuildContext,
        CPUSetCPUs:   "2",
        CPUSetMems:   "12",
        CPUShares:    20,
        CPUQuota:     10,
        CPUPeriod:    30,
        Memory:       256,
        MemorySwap:   512,
        ShmSize:      10,
        CgroupParent: "cgroup_parent",
        Dockerfile:   "Dockerfile", // optional, is the default
        Tags:   []string{"coolimage"},
    }

cli, err := client.NewEnvClient()

buildResponse, err := cli.ImageBuild(context.Background(), dockerBuildContext, buildOptions)
if err != nil {
        log.Printf("%s", err.Error())
}
if err != nil { 
    log.Fatal(err)
}
response, err := ioutil.ReadAll(buildResponse.Body) 
log.Printf(string(response))

defer buildResponse.Body.Close()

但是，这会返回以下错误：

2017/10/22 13:57:42 error during connect: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.34/build?buildargs=null&cachefrom=null&cgroupparent=cgroup_parent&cpuperiod=30&cpuquota=10&cpusetcpus=2&cpusetmems=12&cpushares=20&dockerfile=Dockerfile&labels=null&memory=256&memswap=512&networkmode=&rm=0&shmsize=10&t=dnsimage&target=&ulimits=null: invalid argument

我尝试删除所有BuildOptions并仅保留“Dockerfile”选项，但仍会出现相同的错误。我总是得到无效的论据。

我尝试了所有方法question

我在Mac上运行Docker，但我也尝试在运行CentOS的EC2实例中获得相同的结果。

docker.log或journalctl上没有出现错误我还尝试了github.com/docker/docker/client和github.com/moby/moby/client

Golang Docker API在命中ImageBuild
