使用 yq 对对象数组进行过滤

Vac*_*ano 6 yaml yq

我有一个如下所示的 yaml 文件:

apiVersion: v1
entries:
  blue-green-toggle:
  - description: Used to toggle an application between blue and green
    name: blue-green-toggle

    name: blue-green-toggle
    version: 1.0.16
    apiVersion: v2
  - description: Used to toggle an application between blue and green
    name: blue-green-toggle
    version: 1.0.15
    apiVersion: v2
  istio-config:

    name: istio-config

我试图列出version以 和 开头的数字,1.0.并在该部分中列出standard-helm-chart

到目前为止,我已经使用它来获取以下条目standard-helm-chart

yq eval '.entries | .standard-arup-helm-chart' index.yaml

效果很好。然后我尝试仅获取具有version匹配的行1.0.*。我阅读了 的select文档yq,但它没有指示当您查看对象而不仅仅是字符串时如何匹配。

我试过这个:

yq eval '.entries | .standard-arup-helm-chart | select(. == "1.0.*")' index.yaml

但这失败了。我希望它能够,因为它无法将“1.0.*”字符串与整个对象进行比较。

我也尝试过:

yq eval '.entries | .standard-arup-helm-chart | select(.version == "1.0.*")' index.yaml

我想这会让我yq知道我只想看看这个版本。但它说Error: Cannot index array with 'version'

然后我想我需要尝试数组样式语法:

yq eval '.entries | .standard-arup-helm-chart | select(.[version] == "1.0.*")' index.yaml

但由于解析错误而失败。

我可以发送什么命令yq来获取所有以 开头的版本号1.0.

尝试了一些错误,但这就是我最终得到的结果:

yq eval '.entries.standard-helm-chart.[] | select(.version == "1.0.*") | .version' index.yaml
