How to call toYaml and exclude particular key?

Question

Inside the template I have a fragment like this:

props: {{- toYaml .Values.myApp.container.props }}

currently props contains 4 children:

...
    container:
      props:
        a: ...
        b: ...
        c: ...
        d: ...

But I want to exclude c on the fly. Is there way to do it ?

Answer 1

Try:

{{ $myProps := .Values.myApp.container.props }}
{{ $_ := unset $myProps "c" }}

Then you can use it, for example:

props: {{ $myProps | toYaml | nindent 2 }}

which leads to:

props: 
  a: 1
  b: 2
  d: 4
