# SBOM

Trivy currently supports the following SBOM formats.

- [CycloneDX][cyclonedx]
- [SPDX][spdx]

To generate SBOM, you can use the `--format` option for each subcommand such as `image` and `fs`.

```
$ trivy image --format cyclonedx --output result.json alpine:3.15
```

In addition, you can use the `trivy sbom` subcommand.

```
$ trivy sbom alpine:3.15
```

`fs`, `repo` and `archive` also work with `sbom` subcommand.

```
# filesystem
$ trivy sbom --artifact-type fs /path/to/project

# repository
$ trivy sbom --artifact-type repo github.com/aquasecurity/trivy-ci-test

# container image archive
$ trivy sbom --artifact-type archive alpine.tar
```
