To improve maintainability and reduce redundancy, consider using YAML anchors and aliases to define common blocks of configuration once and reuse them. For example, the `extra_files` list can be defined as an anchor and referenced in each docker configuration.

While `goreleaser`'s configuration schema might limit the use of anchors within `name_template` and `image_templates` combinations, it's worth reviewing if a more concise structure can be achieved to avoid repeating the list of images for each manifest tag version.
