如何从命令行列出和删除 GCP AppEngine 映像？
How can I list and delete GCP AppEngine images from the command line?
我想从 Google Cloud Platform 中删除我未使用的旧 AppEngine 图像，这样我就不会因为存储它们而被收费。
我可以从此 URL 手动列出和删除为我的 GCP AppEngine 项目创建的图像：
https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID
（显然，将 GOOGLE_CLOUD_PROJECT_ID 替换为适当的 GCP 项目 ID。）
有没有办法从命令行列出它们？例如通过 gcloud?
这并不像我预期的那样有效：
$ gcloud compute images list --no-standard-images
Listed 0 items.
这也不行：
$ gcloud container images list
Listed 0 items.
Only listing images in gcr.io/GOOGLE_CLOUD_PROJECT_ID. Use --repository to list images in other repositories.
进入并手动删除很多这些有点痛苦，因为 https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID/US/appengine 下的每个图像都在一个单独的目录中，我必须先单击进入 select 图像，然后单击删除按钮，然后返回到 appengine 目录并为任何其他图像再次启动该过程。
您提供的开发人员控制台的 link 指的是 Container Registry，您的容器映像存储在其中，包括在 App Engine 灵活部署期间创建的那些。
您可以使用以下 gcloud 命令按位置列出这些图像：
gcloud container images list --repository=[HOSTNAME]/[PROJECT-ID]
其中 [HOSTNAME] 是以下四个选项之一：gcr.io、us.gcr.io、eu.gcr.io 或 asia.gcr.io。
然后您可以使用以下命令删除图像：
gcloud container images delete [HOSTNAME]/[PROJECT-ID]/[IMAGE]@[IMAGE_DIGEST]
您可以在网上找到有关它的详细信息 documentation。
列出图片
感谢 LundinCast 的回答，我使用 us.gcr.io 作为主机名，我能够这样做：
$ gcloud container images list --repository=us.gcr.io/GCP_PROJECT_ID
NAME
us.gcr.io/GCP_PROJECT_ID/appengine
显然 AppEngine 使用嵌套存储库：
$ gcloud container images list --repository=us.gcr.io/GCP_PROJECT_ID/appengine
NAME
us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425

us.gcr.io/GCP_PROJECT_ID/appengine/DEF.20181113t163644
这并没有像我预期的那样工作：
$ gcloud container images list --repository=us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425
Listed 0 items.
相反，我必须这样做：
$ gcloud container images list-tags us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425

正在删除图像
根据documentation for deleting images，可以删除...
- 由其摘要识别的图像
- 由标签标识的图像，并且它有多个标签
通过（隐式）标签删除图像
当我尝试删除单个版本/标签时，出现提示：
$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425
WARNING: Implicit ":latest" tag specified: us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425

这对于编写可以自动删除旧图像的脚本或程序来说有点问题（尽管我可以将 yes 命令通过管道传输到 gcloud container images delete IMAGE 命令）；幸运的是，有一个 --quiet 参数可以使用：
$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425 --quiet

所以，这奏效了。
正在按摘要删除图片
在另一张图片上重试，使用摘要删除图片的方法：

惊喜！您不能只使用列出的摘要：

这有点奇怪（只有一个标签，"latest"，甚至在错误中都没有显示）：

好的，让我们使用 --force-delete-tags :

因此，按摘要删除需要更冗长的命令行。
