Cherry-pick particular tagsYou can even cherry-pick particular tags of an image repository.
Save a specific platform (--platform)The --platform option allows you to specify which platform variant of the image to save. By default, docker save saves all platform variants that are present in the daemon's image store. Use the --platform option to specify which platform variant of the image to save. An error is produced if the given platform is not present in the local image store.
The platform option takes the os[/arch[/variant]] format; for example, linux/amd64 or linux/arm64/v8. Architecture and variant are optional, and default to the daemon's native architecture if omitted.
The following example pulls the RISC-V variant of the alpine:latest image and saves it to a tar archive.
The following example attempts to save a platform variant of alpine:latest that doesn't exist in the local image store, resulting in an error.
