关于helm yaml语法

Question

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

表示以下值。Yaml是对的

configmap: |
key=values

而是值。Yaml是错误的

configmap: |
key=values
key2=values2

模板核心内容

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 ':'

如何修复它?

Answer 1

您可以按如下方式更新configmap:

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

由于data.brokerConf中的第2行没有正确缩进而导致错误。如下所示，其中key2=values2在yaml世界中是无效语句，正确的是key2: values2。

configmap: 
key=values
key2=values2

要修复它，我们必须使用indent，但它会额外缩进第一行。为了解决这个问题，使用trim。
