buildx imagetools create [OPTIONS] [SOURCE] [SOURCE...]

Options:

Flag Description
--append Append to existing manifest
--dry-run Show final image instead of pushing
-f, --file stringArray Read source descriptor from file
-t, --tag stringArray Set reference for new image

Description

Imagetools contains commands for working with manifest lists in the registry. These commands are useful for inspecting multi-platform build results.

Create creates a new manifest list based on source manifests. The source manifests can be manifest lists or single platform distribution manifests and must already exist in the registry where the new manifest is created. If only one source is specified create performs a carbon copy.

--append

Append appends the new sources to an existing manifest list in the destination.

--dry-run

Do not push the image, just show it.

-f, --file FILE

Reads source from files. A source can be a manifest digest, manifest reference, or a JSON of OCI descriptor object.

-t, --tag IMAGE

Name of the image to be created.

Examples:

docker buildx imagetools create --dry-run alpine@sha256:5c40b3c27b9f13c873fefb2139765c56ce97fd50230f1f2d5c91e55dec171907 sha256:c4ba6347b0e4258ce6a6de2401619316f982b7bcc529f73d2a410d0097730204
