给定标签`latest`,我们想在Docker Hub上找到具有相同图像ID的另一个标签.

以下是如何使用Docker Hub API v2查找repo的所有标记:

TOKEN=$(curl -s -H "Content-Type: application/json" -X POST -d '{"username": "'${UNAME}'", "password": "'${UPASS}'"}' https://hub.docker.com/v2/users/login/ | jq -r .token)
curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/fluent/fluentd/tags/?page_size=100 | jq

(见gist.github.com/kizbitz)

不幸的是,它不包含图像ID,但始终为此键的"null"值:

$ curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/fluent/fluentd/tags/?page_size=100 | jq

  "next": null,
