How do I use json variables in a yaml file (Helm)

Question

I have a HELM values file which looks like so:

service:
  environment: dev
  spring_application_json: >-
    {
      \"spring\" : {
        \"boot\" : {
          


        

Answer 1

There's an example a bit like this in the docs for spring cloud dataflow but the format in their documentation has the quotes escaped.

I was able to recreate the error and get past it by changing the values file entry to:

service:
  spring_application_json:
    {
      "spring" : {
        "boot" : {
          "admin" : {
            "client" : {
              "enabled" : "false",
              "url" : "http://website1",
              "instance" : {
                "service-base-url" : "http://website2",
                "management-base-url" : "http://website3"
              }
            }
          }
        }
      }
    }

And the deployment entry to:

    - name: SPRING_APPLICATION_JSON
      value: {{ .Values.service.spring_application_json | toJson | quote }}

Notice no quotes around this part as that is handled anyway.
