yq 使用其他 yaml 文件的数组更新 yaml 数组

Question

I dont have any detail knowledge on yq. template1.yaml

spec:
 template:
   temp:
    vars:
      - name: first
        env: []

template2.yaml

env:
 -name: "first"
  value: 1
 -name: "two"
  value: 2

I want to add env array of template2.yaml to template1.yaml's env array using yq. How can we do this??

Answer 1

Which tool called yq are you using?

Using mikefarah/yq (tested with v4.20.2):

yq '
  .spec.template.temp.vars[].env += load("template2.yaml").env
' template1.yaml

Using kislyuk/yq (tested with v3.0.2):

yq -y '
  .spec.template.temp.vars[].env += input.env
' template1.yaml template2.yaml

Output:

spec:
  template:
    temp:
      vars:
        - name: first
          env:
            - name: "first"
              value: 1
            - name: "two"
              value: 2

Note: This assumes, your template2.yaml looks more like this:

env:
  - name: "first"
    value: 1
  - name: "two"
    value: 2
