This command is using the ctr tool to tag an image.

Here's a breakdown of the command:

ctr: This is the command-line interface (CLI) tool for managing container images and runtime in the Containerd runtime environment.

images tag: This subcommand allows you to apply a tag to a container image.

${source_image}:${source_tag}: ${source_image} and ${source_tag} are variables representing the source image and its tag. The source image is the original image that you want to tag. The source tag is a label associated with the source image.

${target_image}:${target_tag}: ${target_image} and ${target_tag} are variables representing the target image and its tag. The target image is the image that will receive the new tag. The target tag is the new label you want to apply to the target image.

So overall, the command is instructing the ctr tool to add a new tag to an existing source image and apply it to a target image.
