如果你在 Docker Hub 上有自動構建倉庫，可以在倉庫中發生某個事件時通過 Webhook 觸發其他應用程式的動作。Docker Hub webhook 在映象構建時，或者新增新標籤到自動構建倉庫時觸發。

在 https://hub.docker.com/r/<USERNAME>/<REPOSITORY>/~/settings/webhooks/ 配置 webhook。

通過 webhook，你可以指定一個目標 URL 用於 POST。Docker Hub 向指定的 URL 傳送的 POST 資料如下：

{
  "callback_url": "https://registry.hub.docker.com/u/svendowideit/testhook/hook/2141b5bi5i5b02bec211i4eeih0242eg11000a/"

        "..."
    ],

注意：如果要測試你的 webhook，建議使用類似 requestb.in這樣的工具。同時，Docker Hub 伺服器無法用 IP 地址過濾。
