### Supported sources
Syft can generate an SBOM from a variety of sources:
Syft can generate an SBOM from a variety of sources including images, files, directories, and archives. Syft will attempt to
determine the type of source based on provided input, for example:
```bash
# catalog a container image archive (from the result of `docker image save ...`, `podman save ...`, or `skopeo copy` commands)
@ -135,26 +136,24 @@ syft path/to/image.sif
syft path/to/dir
```
Sources can be explicitly provided with a scheme:
To explicitly specify the source behavior, use the `--from` flag. Allowable options are:
```
docker:yourrepo/yourimage:tag use images from the Docker daemon
podman:yourrepo/yourimage:tag use images from the Podman daemon
containerd:yourrepo/yourimage:tag use images from the Containerd daemon
docker-archive:path/to/yourimage.tar use a tarball from disk for archives created from "docker save"
oci-archive:path/to/yourimage.tar use a tarball from disk for OCI archives (from Skopeo or otherwise)
oci-dir:path/to/yourimage read directly from a path on disk for OCI layout directories (from Skopeo or otherwise)
singularity:path/to/yourimage.sif read directly from a Singularity Image Format (SIF) container on disk
dir:path/to/yourproject read directly from a path on disk (any directory)
file:path/to/yourproject/file read directly from a path on disk (any single file)
registry:yourrepo/yourimage:tag pull image directly from a registry (no container runtime required)
docker use images from the Docker daemon
podman use images from the Podman daemon
containerd use images from the Containerd daemon
docker-archive use a tarball from disk for archives created from "docker save"
oci-archive use a tarball from disk for OCI archives (from Skopeo or otherwise)
oci-dir read directly from a path on disk for OCI layout directories (from Skopeo or otherwise)
singularity read directly from a Singularity Image Format (SIF) container on disk
dir read directly from a path on disk (any directory)
file read directly from a path on disk (any single file)
registry pull image directly from a registry (no container runtime required)
```
If a source is not provided and Syft identifies the input as a potential image reference, Syft will attempt to resolve it using:
the Docker, Podman, and Containerd daemons followed by direct registry access, in that order.
If an image source is not provided and cannot be detected from the given reference it is assumed the image should be pulled from the Docker daemon.
If docker is not present, then the Podman daemon is attempted next, followed by reaching out directly to the image registry last.
This default behavior can be overridden with the `default-image-pull-source` configuration option (See [Configuration](https://github.com/anchore/syft#configuration) for more details).
This default behavior can be overridden with the `default-image-pull-source` configuration option (See [Configuration](#configuration) for more details).
