关于helm yaml语法

Question

the configmap.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ include "test.fullname" . }}-config-map
data:
  brokerConf: |
    {{ .Values.configmap }}

下面的values.yaml是正确的。

configmap: |
  key=values

但是values.yaml错了

configmap: |
  key=values
  key2=values2

helm模板的核心内容是

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-config-map
data:
  brokerConf: |
    key=values
key2=values2

误差

Error: YAML parse error on test/templates/config-map.yaml: error converting YAML to JSON: yaml: line 9: could not find expected ':'
helm.go:84: [debug] error converting YAML to JSON: yaml: line 9: could not find expected ':'

怎么修呢？

Answer 1

您可以按以下方式更新configmap：

apiVersion: v1
kind: ConfigMap
metadata:
  name: config-map
data:
  brokerConf:
    {{ .Values.configmap| indent 4|trim }}

导致此错误的原因是data.brokerConf中的第2行没有正确缩进。如下所示，在yaml世界中，key2=values2是无效语句，正确的是key2: values2。

configmap: 
  key=values
key2=values2

要修复它，我们必须使用indent，但是它还会缩进第一行。对于寻址，使用trim。
