Docker Run Images with option via Golang Docker SDK

[DineshGuptaa]

Hi All,
I am using docker and wanted to run it pragmatically. I have an image taken vnc images from here and trying to run it from Golang program.
When run docker from Ubuntu CLI then I am able to see the output
http://192.168.53.120/ and able to see the vnc desktop. Command I am running as
docker run -d -p 5901:5901 -p 6901:6901 -p 8888:8888/udp -u 0 ubuntu-xfce-vnc
But same thing I am unable to achieve via Golang and Docker API

package main
import (
    "fmt"
    "github.com/docker/docker/api/types/container"
    "github.com/docker/docker/api/types"
    "github.com/docker/docker/api/types/filters"
    "github.com/docker/docker/client"
    "golang.org/x/net/context"
 )

 func main() {
    cli, err := client.NewClientWithOpts(client.WithVersion("1.38"))
    if err != nil {
            panic(err)
    }
    ctx := context.Background()
    args := filters.NewArgs(filters.KeyValuePair{"reference","gavnc:latest"})
    imgs, err := cli.ImageList(ctx, types.ImageListOptions{Filters: args})

    if err != nil {
            panic(err)
    }
    //fmt.Println("RepoTags \t Created \t Size")
    for _, img := range imgs {
            fmt.Println(img.RepoTags[0], img.Created, img.Size)
            imgTag := img.RepoTags[0]
    if imgTag != ""{
    println("Image Found....Now Running Image...")
        resp, err := cli.ContainerCreate(ctx, &container.Config{
            Image: imgTag,
        }, nil, nil, "")
    if err != nil {
        panic(err)
    }
    println("Id of image:",resp.ID)
    err = cli.ContainerStart(ctx, resp.ID, types.ContainerStartOptions{});
    if err != nil {
        panic(err)
    }
        }
    }
 }

Please guide me how we may pass the option parameters. I am unable to find sample for the same.

Wow , 3 years and no answers .
I faced a similar challenge while performing docker prune .
and after much digging , this worked .

pruneFilters := filters.NewArgs() pruneFilters.Add("dangling", "false")

you might want to take a look at
https://golang.hotexamples.com/examples/github.com.docker.docker.api.types.filters/-/NewArgs/golang-newargs-function-examples.html
to get more ideas .

For anyone else that lands here from Google trying to figure out how to filter images using ImageListOptions. The filters are based on what is available in the Docker API for ImageList, not what is available on types.ImageSummary or anything else in the Go SDK.

For example if you wanted to find a particular image this won't work;

f := filters.NewArgs()
f.Add("RepoTags", "debian:10.12")

You have to do:

f.Add("reference", "debian:10.12")

Then you can get the results like this:

images, _ := m.client.ImageList(m.ctx, types.ImageListOptions{All: false, Filters: f})

The way docker run works is it first calls the create endpoint, if the image isn't available then it returns a 404.
docker run sees that 404 and initiates a pull, then does another create.
