insert at beginning of section

[DrissiReda]

Hello,

I'm trying to modify some files that are later used by templates. I want to know if there is a possibility to insert values at the beginning instead of the end of the section:

Original file

spec:
  containers:
  - name: c

Command:

yq e ' .spec.volumeMounts.name = "data"' file.yml 

Output

spec:
  containers:
  - name: c
  volumeMounts:
    name: data

Desired output

spec:
  volumeMounts:
    name: data
  containers:
  - name: c

I need it to be inserted at the beginning, so that if the template modifies it, I want it to ignore my entry.

Is there any way to achieve this?

I don't understand why it would matter where the position is - regardless, it can be done by creating your map first (which places the property at the top) and then merging in the file:

yq e '{"spec": {"volumeMounts": { "name": "data" }}} * .' data.yml
