如何在更新官方存储库时更新Docker映像？
How do I update a docker image when the official repository is updated?
如果使用Docker Hub创建自动构建，则可以添加存储库链接，它将在链接的存储库更新时重建存储库。
If you are using the Docker Hub to create an automated build, then you can add a Repository Link which will rebuild your repo when the linked repo updates.
如果您想自己进行构建，则可以创建一个hacky解决方法，以通过锂获取通知如上nk所示，并重建一个琐碎的存储库，然后使用 Web挂钩进行通知您的更改的构建系统。
If you want to do the builds yourself, you could create a hacky workaround to get the notification via a link as above and rebuild a trivial repo, then use a Web Hook to notify your build system of the change.

如果您使用Docker Hub进行自动构建，则将触发对BitBucket或GitHub源存储库的更改（包括Dockerfile更改）
If you are using the Docker Hub for an automated build, then changes to your BitBucket or GitHub source repo, including Dockerfile changes, will trigger a new build.
如果您自己构建映像，只需在Dockerfile所在的目录中键入 docker build。。您可以使用-no-cache 强制进行全新的重建
If you're building images yourself, just type docker build . in the directory where your Dockerfile resides. You can use --no-cache to force a completely fresh rebuild

这取决于谁在使用您的图像。当您构建时，结果始终是一个新图像，但是您如何标记却使结果看起来像是
That depends on who is using your images. When you build, the result is always a new image, but how you tag the result can make it seem like a replacement for the old image or something new.
区分同一图像的多个版本的最佳方法是什么？

在名称中使用：tag 功能，例如
Use the :tag feature in the name, eg
ubuntu:latest
ubuntu:12.04
ubuntu:14.04
...
请参见 https：// Registry.hub.docker.com/_/ubuntu/ 以获得 ubuntu映像上所有变体的完整列表。请参见 tag 有关友好图片名称的完整格式的文档。所有标签和名称都是规范映像名称的别名，即运行 docker images --no-trunc 时长的UUID字符串。
see https://registry.hub.docker.com/_/ubuntu/ for a complete list of all the variations on the "ubuntu" image. See the tag documentation for the complete format for a friendly image name. All tags and names are aliases for the canonical image name, that long UUID-looking string when you run docker images --no-trunc.
