helm toJson function orders list alphabetically

Question

I have defined an object with a few attributes in my values.yaml file:

serverOptions:
    defaultUrl:
        p1: abc
        p2: def
    cpu_request:
        p1: abc
        p2: def
    mem_request:
        p1: abc
        p2: def

I am saving these data to a server_options json file in configmap.yaml using this code:

data:
    server_options.json: |
        {{ toJson .Values.serverOptions }}

It works but the initial "list" of attributes gets alphabetically ordered. This is the file's content

{"cpu_request":{"p1":"abc","p2":"def"},"defaultUrl":{"p1":"abc","p2":"def"},"mem_request":{"p1":"abc","p2":"def"}}

Is there a way to keep the original ordering?

Json dictionaries aren't ordered, so no that's not possible. They may be alphabetically ordered when printed but that's only for readability.

Theoretically, one should not count on ordering when working with Json dictionaries, but I was curious about this specific implementation. I guess the ordering here is not for readability purposes but for other technical reasons. – Naigel Sep 18 '19 at 13:10
