我有一个看起来像这样的 yaml 文件:

apiVersion: v1
entries:
  blue-green-toggle:
  - description: Used to toggle an application between blue and green
    name: blue-green-toggle
    version: 1.0.17
    apiVersion: v2
  - description: Used to toggle an application between blue and green
    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:
  - description: Used to configure the cluster level settings of istio.
    name: istio-config
    version: 1.0.4
    apiVersion: v2
  - description: Used to configure the cluster level settings of istio.
    name: istio-config
    version: 1.0.1
    apiVersion: v2
  latest-toggle:
    name: latest-toggle
    version: 1.0.5
    apiVersion: v2
  standard-helm-chart:
    name: standard-helm-chart
    version: 1.1.10
    apiVersion: v2
    name: standard-helm-chart
    version: 2.0.1
    apiVersion: v2
    name: standard-helm-chart
    version: 1.0.34
    apiVersion: v2
    name: standard-helm-chart
    version: 1.0.10
    apiVersion: v2
    name: standard-helm-chart
    version: 1.0.9
    apiVersion: v2

...

我正在尝试列出以version开头1.0.并在该standard-helm-chart部分中列出的数字。

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

那工作得很好。所以然后我尝试只找到version匹配的行1.0.*。我阅读了 的选择文档yq但它并没有说明当您查看对象而不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。我希望它会这样做,因为它无法将“1.0.*”的字符串与整个对象进行比较。

我也试过:

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

认为这会让yq我知道我只想看看版本。但它说Error: Cannot index array with 'version'

然后我想我需要尝试一个数组样式的语法:

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

但这会因解析错误而失败。

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
