This allows the buildx CLI to act a proxy to the configured instance. It allows external code to use buildx itself as a driver for connecting to buildkitd instances. Instance and node selection should follow the same semantics as as `buildx build`, including taking into account the `BUILDX_BUILDER` env var and the `--builder` global flag.

## 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.
|
|
|
|
## 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
|
|
}))
|
|
