I have a configmap which contains a toml file

something like

apiVersion: v1
kind: ConfigMap
data:
  burrow.toml: |
    [zookeeper]
    servers=[abc.2181, cde.2181]
    timeout=6
    root-path="/burrow"

When I am trying to create a helm chart to generate this configmap, I was putting something like:

apiVersion: v1
kind: ConfigMap
data:
  burrow.toml: |
    [zookeeper]
    servers={{ .Values.config.zookeeperServers }}
    timeout=6
    root-path="/burrow"

and in the values.yaml, I put:

  zookeeperServers: [ "abc.2181", "cde.2181"]

However, the rendered value became:

apiVersion: v1
kind: ConfigMap
data:
  burrow.toml: |
    [zookeeper]
    servers=[abc.2181 cde.2181]
    timeout=6
    root-path="/burrow"

The comma is missing. Is there a good way to template this correctly? Thanks!
