A plugin to generate SBOMs (Software Bill of Materials) using [anchore/syft](https://github.com/anchore/syft).
# Usage
The following settings changes this plugin's behavior.
* select_catalogers (optional) comma-separated list of catalogers to use.
* output (optional) comma-separated list of output formats (e.g. `spdx-json=report.json,cyclonedx-json`).
* source_name (optional) name to use as the source in the SBOM.
The source version is automatically derived from `DRONE_TAG` if set, otherwise `DRONE_COMMIT_SHA`.
Below is an example `.drone.yml` that uses this plugin.
```yaml
kind: pipeline
name: default
steps:
- name: sbom
image: nemunaire/drone-syft
pull: if-not-exists
settings:
output: spdx-json=sbom.spdx.json
source_name: my-project
```
Below is an example with multiple outputs and cataloger selection.
```yaml
kind: pipeline
name: default
steps:
- name: sbom
image: nemunaire/drone-syft
pull: if-not-exists
settings:
select_catalogers: dpkg,rpm
output: spdx-json=sbom.spdx.json,cyclonedx-json=sbom.cdx.json
source_name: my-project
```
# Building
Build the plugin binary:
```text
scripts/build.sh
```
Build the plugin image:
```text
docker build -t nemunaire/drone-syft -f docker/Dockerfile .
```
# Testing
Execute the plugin from your current working directory:
```text
docker run --rm \
-e DRONE_COMMIT_SHA=8f51ad7884c5eb69c11d260a31da7a745e6b78e2 \
-e DRONE_COMMIT_BRANCH=master \
-e DRONE_BUILD_NUMBER=43 \
-e DRONE_BUILD_STATUS=success \
-w /drone/src \
-v $(pwd):/drone/src \
