Does that Docker tag actually exist? Real tags, sizes and platforms, live from Docker Hub.
Server tool list (3)
Raw names from tools/list. Only developers need these.
| check_image_tag | Does this image:tag exist, how big is it, and which platforms does it cover? Use this before writing a FROM line or a compose file. On a hit it returns size, platforms, arm64/amd64 support and the digest. On a miss it says whether the IMAGE exists but the tag is wrong, and lists real tags newest first so the caller can correct itself. Defaults to tag "latest" when none is given. |
| get_image_info | Repository facts: official status, pulls, stars, whether it is archived. Use to judge whether an image is the canonical one and still maintained. Archived images still pull but receive no security patches. |
| list_image_tags | Real tags for an image, most recently updated first. Use when choosing a tag rather than verifying one. Each entry carries size and platform list, so a choice can be made without a second call. |
