使用GCloud SDK CLI的GCR图像标签列表 [英] GCR Image Tag Listing using GCloud SDK CLI

问题描述

我正在尝试获取我的私人GCR存储库中所有标签的列表.我可以使用" gcloud容器映像列表标记"来完成此操作命令如下:

I'm trying to get list of all the tags in my private GCR repository. I could do that using "gcloud container images list-tags" command as follows:

gcloud container images list-tags gcr.io/project-id/REPONAME

DIGEST        TAGS          TIMESTAMP
6b5727be962a  0.0.4,latest  2020-06-25T14:14:48
4b8c3f9c6ab7  0.0.3         2020-06-22T08:56:01

不过，我需要将列表弄平，以便我可以将标签"0.0.4"添加到和最新的"在单独的行中.我尝试了以下命令.

However I need the list to be flatten so that i can get tags "0.0.4" and "latest" in separate rows. I tried following command.

gcloud container images list-tags gcr.io/project-id/REPONAME --flatten='[].tags'

这给了我输出，令我惊讶的是重复了" latest ".标记，但省略了" 0.0.4 "

This gave me output which is to my surprise repeating "latest" tag but ommiting "0.0.4"

DIGEST        TAGS    TIMESTAMP
6b5727be962a  latest  2020-06-25T14:14:48
6b5727be962a  latest  2020-06-25T14:14:48
4b8c3f9c6ab7  0.0.3   2020-06-22T08:56:01

我在做什么错，我该如何解决?

What am I doing wrong, and how can I fix this?

推荐答案

我能够复制您的观察结果，并认为这是一个错误.

I am able to repro your observation and think it's a bug.

-flatten 似乎正确枚举了 tags ，但错误地返回了列表中的最后一个值作为每个条目的值.

The --flatten appears to correctly enumerate tags but incorrectly returns the last value in the list as each entry's value.

在我的情况下，如果标签是 v1，v2，v3 ，我得到:

In my case, if the tags are v1,v2,v3, I get:

gcloud container images list-tags gcr.io/${PROJECT}/${IMAGE} \
--flatten="[].tags[]" \
--format="value(tags)" \
--filter="digest=${DIGEST}"
v3
v3
v3

我建议您在Google的问题跟踪器上针对>> Cloud SDK

I recommend you file a bug on Google's Issue Tracker for Cloud SDK

如果您有 jq ，也许:

If you have jq, perhaps:

gcloud container images list-tags gcr.io/${PROJECT}/${IMAGE} \
--format=json |\
 jq -r '.[] | .digest as $D | .timestamp.datetime as $T | .tags[]| {"digest":$D,"tag":.,"timestamp":$T}'

或者:

gcloud container images list-tags gcr.io/${PROJECT}/${IMAGE} \
--format=json |\
 jq -r '.[] | .digest as $D | .timestamp.datetime as $T | .tags[]| [$D,.,$T] | @csv'
