Image and registry exporters (original) (raw)

The image exporter outputs the build result into a container image format. Theregistry exporter is identical, but it automatically pushes the result by setting push=true.

Build a container image using the image and registry exporters:

The following table describes the available parameters that you can pass to--output for type=image:

Parameter Type Default Description
name String Specify image name(s)
push true,false false Push after creating the image.
push-by-digest true,false false Push image without name.
registry.insecure true,false false Allow pushing to insecure registry.
dangling-name-prefix Name image with prefix@, used for anonymous images
name-canonical true,false Add additional canonical name name@
compression uncompressed,gzip,estargz,zstd gzip Compression type, see compression
compression-level 0..22 Compression level, see compression
force-compression true,false false Forcefully apply compression, see compression
rewrite-timestamp true,false false Rewrite the file timestamps to the SOURCE_DATE_EPOCH value. See build reproducibility for how to specify the SOURCE_DATE_EPOCH value.
oci-mediatypes true,false false Use OCI media types in exporter manifests, see OCI Media types
oci-artifact true,false false Attestations are formatted as OCI artifacts, see OCI Media types
unpack true,false false Unpack image after creation (for use with containerd)
store true,false true Store the result images to the worker's (for example, containerd) image store, and ensures that the image has all blobs in the content store. Ignored if the worker doesn't have image store (when using OCI workers, for example).
annotation. String Attach an annotation with the respective key and value to the built image,see annotations

These exporters support adding OCI annotation using annotation parameter, followed by the annotation name using dot notation. The following example sets the org.opencontainers.image.title annotation:
