### How to identity the Dockerfile an image was built from

The Dockerfile that an image was built from can be found given the [image digest](#how-to-identify-the-image-digest).
This is possible by searching [version info](https://github.com/dotnet/versions/blob/main/build-info/docker/image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json) for this repository.

```bash
$ git log -S"mcr.microsoft.com/dotnet-buildtools/prereqs@sha256:4dccac3bd646c9edd1f4645cc52828c8d24d66cfe7d8e8191e3c365d37a1c501" -- .\build-info\docker\image-info.dotnet-dotnet-buildtools-prereqs-docker-main.json

## Additional Info

### Source Folder Structure

The folder structure used in [src](./src) aligns with the tagging convention - `<os-name>-<os-version>-<variant>-<architecture>` or `<os-name>-<os-version>-<variant>-cross-<target>`.
For example, the Dockerfile used to produce the `mcr.microsoft.com/dotnet-buildtools/prereqs:alpine-3.20-amd64` image is stored in the [src/alpine/3.20/amd64](./src/alpine/3.20/amd64) folder.
For example, the Dockerfile used to produce the `mcr.microsoft.com/dotnet-buildtools/prereqs:alpine-3.23-amd64` image is stored in the [src/alpine/3.23/amd64](./src/alpine/3.20/amd64) folder.
The Dockerfile used to produce the `mcr.microsoft.com/dotnet-buildtools/prereqs:azurelinux-3.0-net8.0-cross-arm64` image is stored in the [src/azurelinux/3.0/net8.0/cross/arm64](./src/azurelinux/3.0/net8.0/cross/arm64) folder.

If a Dockerfile is shared across multiple architectures, then the `<architecture>` folder should be omitted.
For example, the [src\alpine\3.20\helix\Dockerfile](./src/alpine/3.20/helix/Dockerfile) is built for all supported architectures (amd64, arm64 and arm) therefore there is no architecture folder in its path.
For example, the [src\alpine\3.23\helix\Dockerfile](./src/alpine/3.23/helix/Dockerfile) is built for all supported architectures (amd64, arm64 and arm) therefore there is no architecture folder in its path.
