Currently can build an image. For example apply these:

```
kind: Secret
apiVersion: v1
metadata:
  name: mydockerfile
stringData:
  Dockerfile: |
    FROM ubuntu
    RUN touch myfile

---
kind: OSArtifact
apiVersion: build.kairos.io/v1alpha2
metadata:
  name: hello-kairos
spec:
  imageName: "quay.io/kairos/core-opensuse-leap:latest"
  baseImageDockerfile:
    name: "mydockerfile"
    key: "Dockerfile"
  iso: true
```
