为 yaml 中定义的键设置默认值

Question

我有关注master.yaml 文件

root:
  - name: First
    some_value: One
  - name: Second
    some_value: Two

和update.yaml 文件

defaults:
  other_value: true
  one_more: Three

预期结果是：

root:
  - name: First
    some_value: One
    other_value: true
    one_more: Three
  - name: Second
    some_value: Two
    other_value: true
    one_more: Three

我尝试了以下命令：

yq eval-all '(select(fileIndex == 0).root.[] *+ select(fileIndex == 1).defaults)' './master.yaml' './update.yaml'

但结果是：

name: First
some_value: One
other_value: true
one_more: Three
name: Second
some_value: Two
other_value: true
one_more: Three

Answer 1

您也可以使用load function 将第二个文件与第一个文件合并。即

yq '.root[] *= load("update.yaml").defaults' master.yaml

OP 似乎在 Windows/Powershell 上运行 yq。在其上执行命令行程序需要额外的引号层。见Quotes on Windows Powershell
