# BuildSourceImage
|
|
|
|
Tool to build a source image.
|
|
The goal is to make retrieving the source code used to make a container image
|
|
easier for users to obtain, using the standard OCI protocols and image formats.
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
$> ./BuildSourceImage.sh -h
|
|
BuildSourceImage.sh version 0.1
|
|
Usage: BuildSourceImage.sh [-D] [-b <path>] [-c <path>] [-e <path>] [-r <path>] [-o <path>] [-i <image>] [-p <image>] [-l] [-d <drivers>]
|
|
|
|
-b <path> base path for source image builds
|
|
-c <path> build context for the container image. Can be provided via CONTEXT_DIR env variable
|
|
-e <path> extra src for the container image. Can be provided via EXTRA_SRC_DIR env variable
|
|
-s <path> directory of SRPMS to add. Can be provided via SRPM_DIR env variable
|
|
-o <path> output the OCI image to path. Can be provided via OUTPUT_DIR env variable
|
|
-d <drivers> enumerate specific source drivers to run
|
|
-l list the source drivers available
|
|
-i <image> image reference to fetch and inspect its rootfs to derive sources
|
|
-p <image> push source image to specified reference after build
|
|
-D debuging output. Can be set via DEBUG env variable
|
|
-h this usage information
|
|
-v version
|
|
|
|
```
|
|
|
|
Nicely usable inside a container:
|
|
|
|
```bash
|
|
$> podman build -t containers/buildsourceimage .
|
|
$> mkdir ./output/
|
|
$> podman run -it -v $(pwd)/output/:/output/ -v $(pwd)/SRCRPMS/:/data/ -u $(id -u) containers/buildsourceimage -s /data/
|
|
```
|
|
|
|
## Examples
|
|
|
|
* Building from a fetched reference [](https://asciinema.org/a/266340)
|
|
* Building from a directory of src.rpms: [](https://asciinema.org/a/266341)
|
|
* Building from a directory of src.rpms and pushing it to a simple registry: [](https://asciinema.org/a/266343)
|
|
|
|
## Use Cases
|
|
|
|
* Build a source image from an existing container image by introspection
|
|
* Build a source code image from a collection of known `.src.rpm`'s
|
|
* Include additional build context into the source image
|
|
* Include extra sources use
