| Description | Proxy current stdio streams to builder instance | | Usage | docker buildx dial-stdio |

Description ​

dial-stdio uses the stdin and stdout streams of the command to proxy to the configured builder instance. It is not intended to be used by humans, but rather by other tools that want to interact with the builder instance via BuildKit API.

Options ​

OptionDefaultDescription
--platformTarget platform: this is used for node selection
--progressnoneSet type of progress output (auto, plain, rawjson, tty). Use plain to show container output

Examples ​

Example go program that uses the dial-stdio command wire up a buildkit client. This is, for example, use only and may not be suitable for production use.

go
client.New(ctx, "", client.WithContextDialer(func(context.Context, string) (net.Conn, error) {
    c1, c2 := net.Pipe()
    cmd := exec.Command("docker", "buildx", "dial-stdio")
    cmd.Stdin = c1
    cmd.Stdout = c1

    if err := cmd.Start(); err != nil {
        c1.Close()
        c2.Close()
        return nil, err
    }

    go func() {
        cmd.Wait()
        c2.Close()
    }()

    return c2
}))
