# Code Engine Source-to-Image Buildpacks support
2+
3+
This sample shows how to use the Code Engine source-to-image Buildpacks feature
4+
to build your application from a git repo, push the image into a registry,
5+
and then deploy it as a Code Engine application. It doesn't require a Dockerfile in the git repo.
6+
7+
More details and supported runtimes and versions can be found in [Code Engine Docs](https://cloud.ibm.com/docs/codeengine?topic=codeengine-plan-build).
8+
9+
The exact steps taken in [`run`](./run) are:
10+
- Login and create an ICR (IBM Container Registry) namespace to store the resulting
11+
image
12+
- Create an IBM API Key that will be used by the build process to push
13+
the image to ICR
14+
- Define a build that points to a git repo for the source, and the
15+
defines where in ICR to store the image
16+
- Creates a Code Engine app from that image
