# OCI exporter
|
|
|
|
The `oci` exporter outputs the build result into an
|
|
[OCI image layout](https://github.com/opencontainers/image-spec/blob/main/image-layout.md)
|
|
tarball.
|
|
|
|
The `docker` exporter behaves the same, however, it exports a docker image
|
|
layout instead.
|
|
|
|
## Synopsis
|
|
|
|
Build a container image using the `image` exporter:
|
|
|
|
```console
|
|
$ docker buildx build --output type=image[,parameters] .
|
|
```
|
|
|
|
The following table describes the available parameters that you can pass to
|
|
`--output` for `type=image`:
|
