google-app-engine - 如何从命令行列出和删除 GCP AppEngine 图像？

Question

我想从 Google Cloud Platform 中删除旧的未使用的 AppEngine 镜像，这样我就无需支付存储它们的费用。

我可以从此网址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，请将 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工作:

$ gcloud compute images list --no-standard-images
Listed 0 items.

这也不是:

$ 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.

由于 https://console.cloud.google.com/gcr/images/GOOGLE_CLOUD_PROJECT_ID/US/appengine 下的每个图像，手动删除大量这些图像有点痛苦。位于一个单独的目录中，我必须首先单击该目录来选择图像，然后单击删除按钮，然后返回到 appengine 目录并针对任何其他图像再次启动该过程。

列出图像

感谢 LundinCast 的回答，我使用 us.gcr.io 作为主机名，并且能够执行此操作:

$ 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/ABC.20181110t154726
us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t162317
us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181113t132223
us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181113t150454
us.gcr.io/GCP_PROJECT_ID/appengine/default.20181108t184629
us.gcr.io/GCP_PROJECT_ID/appengine/default.20181108t205831
us.gcr.io/GCP_PROJECT_ID/appengine/DEF.20181113t163644

但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 
DIGEST        TAGS    TIMESTAMP
c8e3797d36b2  latest  2018-11-10T12:57:58

删除图像

根据documentation for deleting images ，可以删除...

• 通过摘要识别的图像
• 由标签标识的图像，并且具有多个标签

通过(隐式)标签删除图像

当我尝试删除单个版本/标签时，系统显示了一个提示:

$ 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

ERROR: (gcloud.container.images.delete) Aborted by user.

这对于编写可以自动删除旧镜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 容器镜像删除 IMAGE 命令中)；幸运的是，有一个可以使用的 --quiet 参数:

$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425 --quiet
WARNING: Implicit ":latest" tag specified: us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425

  Associated tags:

所以，这有效。

按摘要删除图像

再尝试另一个图像，使用删除图像的摘要方法:

$ gcloud container images list-tags us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726
DIGEST        TAGS    TIMESTAMP
4d860e73f85f  latest  2018-11-10T15:50:55

惊喜!您不能只使用列出的摘要:

$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726@4d860e73f85f
ERROR: (gcloud.container.images.delete) [us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726@4d860e73f85f] digest must be of the form "sha256:<digest>".

这有点奇怪(只有一个标签，“最新”，而且错误中甚至没有显示):

$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726@sha256:4d860e73f85f
ERROR: Tags:
ERROR: (gcloud.container.images.delete) This operation will implicitly delete the tags listed above. Please manually remove with the `untag` command or re-run with --force-delete-tags to confirm.

好的，让我们使用--force-delete-tags:

$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726@sha256:4d860e73f85f --force-delete-tags

  Associated tags:
 - latest
This operation will delete the tags and images identified by the digests above.

Do you want to continue (Y/n)?  n

ERROR: (gcloud.container.images.delete) Aborted by user.

和以前一样，让我们​​使用 --quiet 来防止显示提示:

$ gcloud container images delete us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t154726@sha256:4d860e73f85f --force-delete-tags --quiet

因此，通过摘要删除需要更详细的命令行。
