google-app-engine - 如何从命令行列出和删除 GCP AppEngine 图像?
问题描述
我想从 Google Cloud Platform 中删除我未使用的旧 AppEngine 图像,这样我就无需为存储它们付费。
我可以从以下 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下的每个图像都位于一个单独的目录中,因此手动进入并删除这些图像有点痛苦,我必须先点击进入选择图像,然后单击删除按钮,然后返回到 appengine 目录并再次开始处理任何其他图像。
解决方案
列出图像
感谢 LundinCast 的回答,我使用 us.gcr.io 作为主机名,并且能够做到这一点:
$ 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
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
根据删除图像的文档,可以删除...
- 由其摘要标识的图像
- 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
当我试图删除单个版本/标签时,我看到了一个提示:
$ 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
Digests:

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.
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命令通过管道传递到gcloud container images delete IMAGE
命令中);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
WARNING: Implicit ":latest" tag specified: us.gcr.io/GCP_PROJECT_ID/appengine/ABC.20181110t125425

所以,这行得通。
通过摘要删除图像
在另一个图像上再次尝试,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”,甚至没有显示在错误中):
$ 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,按摘要删除需要更详细的命令行。
