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!
Here is one solution, in the values.yaml put
zookeeperServers: |
[ "abc.2181", "cde.2181"]
solves the problem.
Try this, servers=[{{ .Values.config.zookeeperServers | join "," }}]
. Quoting could get weird if you put TOML metachars in those values, but for simple things it should work.
